German quality and loaded with features, the Hammerli 850 AirMagnum is so much fun to shoot that you'll have a hard time putting it down. Let's start with the all-weather stock. You can take this gun anywhere and not worry about a fragile finish, because it's made from a durable polymer. It's ambidextrous, too, with a raised cheekpiece on both sides of the Monte Carlo stock!

This CO2 rifle uses an 88-gram AirSource cartridge, giving you about 200-250 shots before you have to change cartridges. The fiber-optic sights will help you acquire your target, but feel free to mount a scope on the 11mm dovetail rail. (Umarex also makes a dovetail-to-Weaver mount) The checkering on the pistol grip and forearm will help you get a good grip while you plow shot after shot from this 8-shot repeater. This gun is everything you ever hoped for in a CO2 repeater!

The fun never stops with this rifle! Ideal for plinking, shooting targets and spinners.

Hammerli/RWS is known for standing behind their guns, and their warranty has always been viewed as the best in the business. Made by Umarex for RWS.

What Are You Buying? German Quality & Accuracy!
May 17, 2012
My 850 .22 arrived today and I am blown away (pun intended). I own over 30 air pistols and air rifles (not to mention more than a dozen firearms) and the 850 quickly rose into my top 5 favorites. Here's why: PROS: The all-around general feel of the weapon is superb. It looks, acts and feels like a quality product. And it is. The best OEM trigger of any of my 30+ air guns. I actually had an NG (negligent discharge) as I was bringing the rifle up to my shoulder to fire (still hit the target, but I wasn't ready to fire). I am very used to hard triggers on these <$1000 guns, but the 850 trigger is very light and crisp. It is a true joy to shoot. The action appears to be all metal, aside from parts of the safety knob and the magazine is partially plastic, too. The rest, however, is all high quality, well-painted steel. The bolt operates and slides smoothly. I haven't had a jam or issue yet with 100 shots fired so far. The magazine is easy enough to load and insert into the weapon. The sights are great! They are glow in the dark and provide great ease in identifying your target. Accuracy was spot-on, right out of the box, at 50'. This is my first purchase involving 88g AirSource rifles. I'm pleased with it. A high shot count with consistent fps. CONS: I personally can't stand synthetic stocks. Yes, they have their advantages, but give me a good old wooden stock any day. Had the 850 been offered with a wood stock variant, I would have gladly spent $100 more on it. You can adapt a wooden stock to this, but you often lose the AirSource cover functionality. The sights sit pretty high on the barrel. This is the first rifle I've ever found, I think, that would benefit from a cheek riser for me. Folks are complaining that the butt stock feels hollow and flimsy. Some have filled theirs with expanding foam from the hardware store. I may end up doing exactly that. A little more weight on the rear wouldn't hurt anything, anyhow. The safety engages after every shot. It's a politically correct, unnecessary, pain in the butt. I'm sure that can be modded out, but it's a frustrating "feature" to have out of the box. I don't expect any manufacturer to offer both left- and right-hand bolt action pellet rifles, but it'd be nice. If I could get this with a left-hand bolt, I'd pay $1000 for it. OTHER: Despite my CONS, which are more personal grievances and peeves than anything, you should 100% buy this rifle and now. If you are looking for a quality, recoil-less, extremely accurate bolt action repeater, you need not look any further.

September 19, 2019
I don't have a lot of experience with weapons, other than my time in the Air Force.

I decided at my ripe old age to pursue one of my bucket list things, and that is target shooting. I purchased this because I could shoot without having to cock a lever or handle. I don't have the strength to constantly be doing that.

I like the fact you can get over 200 shots from one 88 gram CO2 cartridge. It was very easy to install the CO2 cartridge.

Shooting it is so easy. You just pop in the pellet magazine, throw the locking mechanism, throw the bolt, release the safety, and squeeze the trigger. I like the fact that the safety is engaged after each bolt cocking. It helps prevent an inadvertent shot while getting set on the target.

I am shooting bench rest, at 25 yards, using 10 meter targets. For the most part, I am hitting inside the outer target ring about 40 percent of the time, and in the black about 60 percent of the time.

At age 69. my skills are not like they were when in my 30's. My aim tends to wander in bigger circles than back then.

From what I have read and experienced, this CO2 rifle is pretty accurate. I am sure that with more experience, my shot groups will improve.

I can't really evaluate all the technical parts of the rifle. I just don't have the experience. The trigger seems fine for me. It seems easy to squeeze, unlike what I remember of some powder burners that required a heft squeeze. The one thing I am disappointed is the stock. I wish it had some kind of adjustable cheek piece. I also wish it had the two different types of scope mounts. Since I have Picatinny scope rings, I had to purchase an adapter which has caused my scope to be higher than desired. Of course, that can be fixed by purchasing different scope rings.
ProsEasy to set up and use. Good trigger. Accurate at 25 yards
ConsNot really Cons, but these would be nice. Picatinny and 11 mm combo accessory rails. Adjustable cheek piece. I used foam and animal leg bindings to create a higher one. Wood version replacing the synthetic

After conducting much research and comparisons (I was looking specifically for a CO2 repeater), I selected the Hammerli 850. Everything seemed to be as advertised until about two months later when I would begin experiencing situations where the bolt would not retract far enough to charge the gun. I went on line hoping to gain some insight and found a chat room where several owners were experiencing the same thing. Some of the recommended 'fixes' actually involved taking out and cleaning the entire trigger assembly -- ridiculous. This is obviously a systemic problem. As a result, I'm about to find out how well AirGunDepot's Customer Service department is as I want to exchange the rifle for a different brand.

March 27, 2019
This is a very accurate Air Rifle. The multi-shot capability makes it really fun to shoot. I've paired the rifle with a taped Compensator and the noise level is very low, which is highly desirable in my Southern California suburban neighborhood. I'm using the Walther CO2 adapter which utilizes two-12gm CO2 cartridges. I'm getting over 60 shots out of the 2 cartridges. So far, I have no negative issues with this gun.
ProsVery accurate Very economical using 12gm CO2's
ConsIt could be a bit lighter in weight, but that's only a concern to old guys like me

I got the version with the wooden stock and 12oz co2 adaptor, and silencer. Very accurate and easy to use. Got this as it is not easy to own firearms in the UK, this is possibly the next best thing. The kit came with bipod and scope and is good value for money. Great for shooting rabbits on my son's farm land.

Well made rifle, design is excellent. I use RWS or JSB domed pellets , feed and loading has been
perfect with these pellets. No jams. When cycling bolt, make sure you bring it back all the way to
ensure rifle is cocked, If it wants to spring forward you havent got it cocked yet. The bolt is a little
stiff but it should smooth out with use. Load mags by pushing in until oring catches pellet around waist

Best Usestarget shooting
By Scott S.
Southern Louisiana
a popular option for more than 10 years because it's a great gun
March 27, 2018
I bought the Hammerli 850 .22 and I absolutely love shooting this gun. I researched different options for days and settled on this one because there's no cocking or pumping required. I feel shooting targets should be enjoyable and not a workout. And being in Louisiana where it's often warm and moist the least amount of effort required to shoot the better. This gun is accurate and is a breeze to shoot. Out of the box the sights are perfect. At 30 yards I'm knocking down the rat on the run - (awesome target BTW) a good bit and rarely miss the rat when not hitting dead center. This may not sound impressive on the surface but at 30 yards that sweet spot is merely a blur of a yellow dot. Another reason for getting this gun was because it comes with open sights and not a scope. When searching I sought out guns that had open sights because I think there's more challenge to it. I've shot one air cartridge in 2 shooting sessions so far which yielded plenty enough shots. I used Pelgun oil on the tip and threads of the cartridge when installing it. I shot 130 pellets the first session and didn't want to waste the Co2 so I left the cartridge in the gun. The intention was to shoot the second session the following weekend but that turned into three weekends. The gun fired perfectly for another 50 shots or so until the air loss was getting noticeable. Even then the accuracy was good and it still had enough oomph to knock down that stinkin' rat. Four other family members also shot this gun (novices) and after a few attempts were decent shots. But most importantly they were smiling the whole time and enjoying themselves without breaking a sweat. And to me that's what this is all about.

Airgun Depot was also awesome. The gun shipped extremely fast and arrived before its expected time. UPS didn't show until 8 or so and I was pacing the house anxiously awaiting the arrival of my new toy. I was not let down.
ProsSo far everything. The quality of this gun is outstanding. There's a reason it's been around as long as it has. No pumping or breaking barrels (perfect - if you're kind of lazy and just want to shoot let the Co2 do the work) 8 shot magazine Extremely comfortable Excellent open sights I bought the Benjamin 400 count pellet assortment and they all shot well
ConsBeing VERY picky I'd have to say loading the pellets into the magazine. You cannot push the pellets in far enough if you've got normal human sized hands. No problem though, I cut a few pieces of a wooden dowel which is perfect to seat the pellets all the way in. Again - this is really really looking for something. It's not a big deal at all. Just know you might need a tool to seat the pellets completely.
Best UsesEverything you'd realistically want to do with an airgun.

I wish I'd known about this gun!
March 27, 2018
With the name Hammerli, I should have expected an accurate rifle, but this thing is crazy! I use targets with ten bulls eyes, so I don't have to change them as often, and after three shots I go to the next one as the pellets are going through the same hole. I mounted a high end scope on it because the gun is more accurate than my eyesight is. All of my other pellet guns are single shot, so having an eight shot clip is really nice. If I had only known how great this gun was, I could have saved a lot of money buying other ones that are more expensive, but not as "user friendly". I did have to modify my pellet trap as the power level was damaging the steel deflector plate. Great gun!
ConsIt makes you look stupid for spending all that money on high end guns.
Best UsesTarget, hunting, plinking, or anything else you can think of doing with a pellet gun!

Hammerli 850 air magnum .177 cal
December 20, 2017
I purchased this rifle from AGD on 12/11/17 in .177 cal and it shoots almost as straight as a pcp at up to 40 yds. That is amazing considering outside temperature was about 48-52* F. I was hitting close to 1/2 inch ctc consistently at about 60-70 shots until the wind picked up to about 15-26 mph then the pellets started to drift a bit. After the wind died down a little I was getting 1/2 inch ctc again for about 40-45 more shots. Because of its accuracy and consistency you tend to forget you a shooting a co2 gun and not a pcp despite velocities at around 745 FPS with 7.3gr JSB pellets.

The gun feels excellent to hold and aim and you feel you can hit your target at any distance. This gun thinks it is an FX Impact. Just mount a good scope sight in your target at about 35-40 yds wait till outside temperature hits 80-85* F and there is no way you can miss. Only downside is its low 8-9 ft lbs of energy to kill sparrows and chipmunks but probably not squirrels.

When warmer temperatures rise to 80-85*F as it is in the warm months of July and August and light winds I know I can confidently take out sparrows and chipmunks at up to 40 yds with this rifle. All you need to do is stock up on plenty of 88g co2 canisters and fire away and mostly likely you will be bagging pounds of chipmunks and sparrows.

ProsExcellent aim and shouldering Lightweight Accuracy at up to 40 yds with no wind High consistent velocity and shot count at up 150 shots flying at 700-750 FPS if you wait about a minute between shots No gun powder residue to clean of barrel Excellent bang for your buck when compared to shooting gunpowder and ammo
ConsIf only it can House a larger co2 canister so you dont have to change it after about 150-160 shots Why didnt I discover this sooner

Just got this gun in 2days ago. I had been wanting to purchase this gun fora while now but was hesitate on pulling the trigger. I read all the reviews and decided, what the heck. Now im very very very happy i did. I got the .177 refurbished version and the gun is flawless. Im getting dime sized groups at 25 yards with the 8.4gr air arms pellets. This thing is a killer. I shot a squirrel yesterday and took it out no problem. The squirrel as a real problem for me. Tearing up my patio chairs stealing the insulation padding. Guess I don't have to worry about that now. But if you're on the fence about this gun, i suggest that you just go with the reviews and just buy it. For a gun to have this many 5stars, it has to be a good reason behind it

June 16, 2017
My review is not much different than the others , this gun is a joy to shoot and with the right pellets it is a tack driver ( I am talking same hole shots at 20 yards ! )
Be sure to buy the 12gram C02 adapter tube so you can be ready to shoot anytime ! I also purchased the compensator and put tape over the holes as talked
about on YouTube ,the neighbors cant hear a thing .... very quite .
ProsSuper accurate and fun to shoot , the product is well made and should last a lifetime if taken care of.
ConsThe only problem that I have had with this rifle is with the revolving pellet holder , it does not advance to the next pellet when you pull the bolt back like you think it would ?

hammerli 850
June 6, 2017
Purchased my .177 Hammerli 850 in May 2017. Gun is of very fine fit and finish. What else, its German. Fiber optic sights are bright and usable. Trigger pull arrived at 1#, I reset it to 3# which was the maximum adjustment. Weight and balance seemed right on. New 88 gram bottle provided 650 fps at 62 degree/45 rh. 8.2 grain wad cutter. Mounted a scope rather soon and shot 1 groups from sand bag at 20 meters. Mags easy to install. I put a hash mark on them so I knew when they were finished. Bolt requires very firm pull to rear to reset safety and trigger. A reset safety does not mean the gun has been cocked. Ive experienced quite a few failures to cock. (to many). This situation requires removal of the mag to avoid loading two pellets into chamber as you recycle bolt. Time will tell if this is due to stiff action on a new gun, or a design flaw. This is my first experience with the 88 gram CO2 canisters. Im disappointed. Puncture a seal to use, discard when empty is antiquated technology from the 1950s. On a cold day they are underpowered, on a hot day must be protected from overheating. Central Valley of California is 100+ most days of summer. It is recommended that the 88s not be left in gun after shooting. Unless your shooting session is 150-200 pellets, you need to dry fire the gun till bottle is empty. Second choice is unscrewing a bottle that still contains pressure. Unscrewing means you are freezing the O ring that seals the CO2 cartridge. When it fails, removing stock from gun is your means of access to seal. It only stands to reason that these bottles have valves for shut down and removal. The ability to recharge the 88s is only logical too. Why should they end up in the trash? Im sure these options were solved years ago by the manufacturers. Alas, more money can be made selling disposable bottles. Love this gun though not likely to ever again buy a gun reliant on 88-CO2 bottles.
ProsVery accurate. Cosmetically great.
ConsOccasional failure to reset trigger. Co2 system.

This is a great air rifle!
April 5, 2017
This is my first CO2 rifle but I've owned several pistols. I have shot break barrels up to this point and have been frustrated with their accuracy. Out of the box this rifle felt good and shot accurate, even with open sights! I put a scope on it that same day I received it and have been hitting like a pro. The accuracy is amazing and it will be hard to go back to my break barrels again! Because of this, I purchased another one for the females to shoot so they don't mess with mine! lol German quality is hard to beat in products like this and similar. Hammerli 850 Magnum .177 with 3-12X44 Hawke Vantage! A very accurate combination!
ProsEverything about this gun is good
ConsJust a little on the physical heavy side. But then I bench rest it!

This should be your first air rifle...
March 31, 2017
Like many of us, I have a pretty diverse collection of air rifles. My first foray into the air rifle world were a couple of break barrels simply because they were fairly inexpensive, easy to use and seemed to be the way to go at the time. Then, a Benjamin 392, a 1377 a 1322 and now the Hammerli 850.I have to say that I wish this had been my first air rifle. It is incredibly accurate out to 25 yards. And I mean pellet on pellet. Im using a UTG Bug Buster scope and RWS super domes. Im not a particularly good offhand shooter so I was thrilled to get such tight groups. Some complain about the trigger and safety but the trigger is actually very crisp on my unit. The safety? I'm never too picky about making something safer. You'll get over it. Im using 88gr cartridges but have purchased a 9oz adaptor to extend the shot count. The simple fact that I have an 8 shot repeater (with an upgraded spring) that will exceed 650fps (.22) and hold a group the size of a dime for under $300 is amazing. You could always covert these to HPA but why? It's a great rifle. You will NOT be disappointed.
ProsExtremely accurate, easy to use, nice trigger, RWS pellets easy to acquire, upgradable. Did I mention accurate?
ConsLower fps for Co2 in colder weather but Im in Texas so... Upgrade the hammer spring to eliminate valve lock in hot summer months.

Very Impressive Weapon
February 13, 2017
I know the Airgun Depot attorneys will cringe on seeing the word weapon, but this .22 rifle is one impressive weapon. About the size of an M-4, it has impressive weight, heft, and accuracy. I've been putting shots on target from 12 yards out, but it feels like I could be accurate from 30 yards out. This weapon just wants to put rounds on target and get them there in a hurry. The amazingly large 88 gram CO2 cartridge lasts a long time and doesn't appear to leak at all. This is the first time I've used a fiber-optic sight and it really helps me sight in to target - especially since I don't have the world's greatest vision.

Lastly, a shout out to John, who did a great "Under Pressure" video on the Hammerli. Sorry you lost the shoot out!

ProsThe eight round magazine gives the weapon great functionality. No single shot here. The slide needs to be engaged each shot. But it has a nice feel and gives each individual shot a purpose. I was a little concerned about the need to take the weapon off safe each shot. But the safety is in such a perfect location that it's not an issue at all. I wanted a .22 caliber rifle to go with my .177 Sig Sauer pistol. I wanted power and accuracy and I got it. A great .22 rifle - it feels like an old friend.

December 24, 2016
I got this rifle with expectations of a 1 inch 5 shot group at 10 yards. The first thing I did when I got it was mounted a scope, then started shooting. I shot a 8 shot group at 10 yards and noticed it was pellet on top of pellet. So I backed up to 20 yards. I got the same results. I also noticed it had more than enough power to take a squirrel or pest. I kept testing out to 50 yards and was amazed with the results. So I decided to keep moving out. What I found is that the rifle has the power and accuracy to take pests and small game out to 70 yards. Very impressed with this rifle. You should pick one up!!!!
ProsGreat barrel, great 8-shot rotary mag, amazing quality. In my opinion best rifle under 300$. Pcp features accuracy and quality. Great shot count.
ConsCo2 isn't the best in cold weather. 88g Co2 tanks are hard to find in store, easy fix with 12g adapter.

Perfect for eliminating varments
November 4, 2016
We have an iguana problem here in Florida. The Hammerli 850, 22cal is perfect for this. The construction and balance of the rifle is exemplary. The lizards are basically no more than 25-30 feet away. It is nice to have an eight shot rifle. On one say I was able to eliminate 3 of 4 iguanas in a few seconds. The accuracy of the rifle is excellent. After mounting a scope from an older dysfunctional rifle it was even better. Iguanas are not indigenous to Florida. They destroy allot of different plants by eating the new leaves as they come out. My Hammerli is curing the problem of the uninvited guests.

PCP accuracy without the price
October 20, 2016
Just received my 22 cal 850 today - 10.20.2016. Having squirrels climbing on the side of my home to get to the roof, I needed something to eliminate them without fear of injury/property damage to neighbors. I needed the accuracy of my pcp's with the lower power of a plinking co2. Distance of 35 yards shooting at 30 degree elevation. Since I'm shooting at their silhouettes along the side of my home and not directly at my home, there's a chance of missing or over penetration. So, after much research, I decided on the Hammerli 850. I've spent the better part of three hours putting it through some tests. At 30 yards, I can get 150 shots on one tank with less than a 3/4" difference in original POI and shot #150. After that, it tends to drop off in clusters of 16 shots or so. I also ran that test prior to barrel cleaning or mounting a scope. While it came with a free refurbished CP, it has not arrived. I put a Burris 2-7 Rimfire on it and started shooting again. I'm currently at 32 shots that I can cover with a dime. Again, this is 30 yards. I'm taking it to the range next week and will see how it does at 50. The action is extremely smooth. The only adjustment was to the open sights and reducing the trigger travel. Trigger is light enough to do what I need and more. Weight is good and the cheek weld/LOP fit is solid. I'm just really impressed with this air rifle. Never written a review before but this one definitely deserves it! I'll be picking up a couple more for my kids. They've outgrown their 1077's and I'm sure they'll love this one. Nutshell - Very accurate, high shot count, smooth action and powerful enough to take care of pests safely and humanely.

Quarter Target - Breezy with Open sights (front rest only) @ 30 yards, JSB Diablo pellets, 225 shots total. Target includes sight adjustments. 16 shots at center of diamond. Last 8 shot group at bottom of center diamond. Notice that even after velocity drop off, groups are still pretty tight.

Dime Target - Breezy with Scoped (6x power, front rest only) @ 30 yards, JSB Diablo pellets, 32 shots so far. Target includes scope adjustments.
ProsInexpensive for the accuracy and shot count. I've spent 3x's as much on pcp's with the only difference being significantly more power but with less shots per fill. However, every rifle has it's purpose and this one fit my particular need perfectly.

Right out of the box this rifle showed quality workmanship. Nice easy to see fiber optic sights. Easy to load clip and easy action. Almost dead on out of box.

I love everything about this rifle. It has a beautiful appearance that "shouts" quality, and it shoots just as accurately as it looks. I've shot about 250 rds of .22 14gr RWS Meisterkugeln wadcutters through it at 10 mtrs and it is almost boringly accurate, I'm talking shot after shot through the same hole, this gun will shoot as accurately as your technique allows. I've also shot it at up to 25 yds and it has plenty of power to group well at that distance. If you buy this gun, you will love it!
ProsWonderfully smooth trigger!
ConsNot really a con, just a couple of tips. Make sure that you pull the bolt all the way back, that will insure that the magazine rotates properly as you push it forward. Short stroking the bolt will chew up the magazine. Also, the Air Venturi pellet pens work really well for loading and seating pellets in the magazine.

Refurbished now good as new...
March 1, 2016
I snapped up a refurbished Hammerli 850 .22 cal as soon as I saw the ad. I was initially disappointed with a slow leak from the cylinder and less than 500FPS with 14.5g Daisy wadcutters. Then I contacted Umarex and they sent a new o-ring to seal the cylinder and now I'm seeing 585FPS (~11FPE) with less than 70 degree temps outside. I'm sure I'll see more than 12FPE when the warmth kicks in. Besides that, I put five of those cheap pellets within a half-inch center-to-center at fifteen yards. All I can say is the pests better stay away.
ProsDecent power. Amazing accuracy.
ConsAGD doesn't repair this model so refurbs may require a bit of knowledge and TLC to get 'em up to spec.

Good purchase
February 18, 2016
Bought this for squirrel hunting because a recent elbow injury makes cocking my break barrels less than enjoyable. Surprisingly this 850 was shooting 1/2 inch groups at a measured 25 yards to point of aim right out of the box.

I notice there were complaints about pellets falling out of the magazine and about the magazine not indexing and allowing pellets to fall into the action. The rubber band can't grip some short pellets unless you seat each pellet into the magazine with a pellet seater (or ball point pen, or dowel or any object small enough to do the job your finger is to large for). This seats the pellet deep enough that the rubber band can hold it. The ONLY WAY I could duplicate Patsy's problem with the magazine not indexing and pellets falling from the bolt was if I did not push the magazine retaining lock forward to lock the magazine into the breech - operator error.
ProsGreat trigger ( about the best out of the box I have encountered ), decent open sights in an era when many rifles come without sights, plenty of full power shots per CO2 cartridge plus cartridge adapter option ( although the adapter is more than a little overpriced )
ConsThe only con I can honestly come up with is that I didn't get a Hammerli 850 long ago.

Outstanding Value
February 17, 2016
I was incredibly impressed with the accuracy and range of this rifle. I bought my father the .22 and myself a .177. I'm still kicking myself for not getting the .22. My father was able to take down a crow at about 100 yards. The rotary mag functions flawlessly and the bolt cycles quickly. For the price, it's an outstanding value.
ProsHi accuracy. Good range and power. Smooth mechanics.
ConsCO2 can be costly and hard to find sometimes. The .22 is prone to jamming with some pellets. The .177 eats anything.

If you want accuracy, this is the one
November 19, 2015
First, the good. It is very accurate. At the indoor range at 60 feet, it took about 8-10 shots to adjust the 3-9X32 scope. Since the scope has 3-9X variable power, after settling on 7X using the full length of the range, I could see the pellets were hitting exactly at my point of aim. So, the rifle is accurate which is it's biggest selling point. The trigger is excellent. I didn't touch it from the factory setting. The CO2 adapter is also excellent. Easy to load, at least 65-75 shots on two cartridges with consistent power. The adapter can be left 'loaded', and it unscrews easily from the rifle. If the gun is shot regularly it will pay for itself quickly.

The rifle handles well. It is heavy compared to some others I have, but with a rest it is very stable. It's also seems quiet, even without quieting the muzzle even more with tape or heat shrink. The bolt is relatively easy to cock, but it does take a good pull and push to operate it. Once I started using the palm of my hand, it was fine. If you don't let it know who's boss, you will be rewarded with either an apparent jam or a misfire. It only happened a few times to me early in the game. My fault, I didn't cock it properly with enough authority.

I think it's pellet sensitive. That fault can be overcome easily but I think guns should eat up all pellets. The Ham would not allow me to cock it consistently with one of the Crosman round-nose pellets I used today which immediately put the pellet on my 'do not use' list for this gun. Loading the cartridge requires gently pushing of the pellets with a plastic pen tip until they sort of 'lock' into the clip. Not a big deal, but if you don't lock the pellets in you risk a jam if one falls out into the gun's action.

On the second set of cartridges I was tearing the bulls eyes out of the targets with the occasional flyer because I pulled the trigger instead of squeezing it. The gun will reward tight groups if you do your part consistently.

German engineering gets a good grade on this gun. All the parts fit, it looks nice, the clips slide right in and lock OK every time. Finicky pellets need to be watched. I have more RWS pellets on order.

Overall, I'd give the gun an A-. It has a personality. I'm happy to have it. It's nice quality and I'm glad I bought it. The Hammerli is an accurate gun, quality trigger, quality features, probably will be durable in the long run, and well-engineered. The Ham is heavy.

I would be remiss if I didn't mention the two QB78 rifles I have, one a 22, one a 17. These are also quality guns, bolt action, one pellet at a time loading. Accurate, maybe as good as the Ham even. Easy to handle. Weigh about the same or a bit less. Not pellet sensitive. Quality, adjustable triggers. Nice looking guns with wood stocks. And the best part... $112 DELIVERED from Air Gun Depot!

ProsTrigger, quality engineering, accuracy.
ConsEight pounds fully loaded, long gun with the suppressor installed, pellet sensitive (likes RWS), has a personality you need to figure out.

Fantastic rifle after some work.
September 22, 2015
First problem is that when the CO2 gets hot the gun will not fire or lose power. Out of the box it shoots 550fps 14.3gn. On a hot day it will drop to 430. The reason is valve lock. The hammer spring can't hit the valve hard enough to open the valve. The trigger is very light but it's NOT a 2 stage trigger! I wish ALL these companies would quit lying about the triggers. 88gram CO2 is too expensive. $5 a bottle for 200 shots.

First thing you need to do is tear it down. Don't even bother to fire it out of the box nor put on a CO2 tank. Remove all the grease and lightly lube it with a light quality grease. Polish the valve hammer. It scrapes in the action housing. You'd think we'd get better for a German made rifle. Add three small orings inside the hammer where the spring sides in. This adds .2" preload on the spring to hit the valve harder. If want a two stage trigger now is the time, I think it's a 5/32 drill bit glued onto the trigger to hit the sear first.

Now you have a good rifle that fires 650fps to 700fps. If you want to save some $, get the 9oz bottle adapter. Pack the rear stock with foam since it's hollow. Now your ready to go.
ProsSuper accurate. Repeater.
ConsNeeds work out of the box.

This air rifle is a real sweetheart, a real tack driver. With the Hawke scope I can easily hit 1/4 moa @ 25 yards. It is not hold dependent and easy to shoot. The trigger breaks easily and is crisp and clean. I added the TKO Hammerli suppressor and it is now whisper quiet.
ProsClean trigger break, Accurate, Not hold dependent, lightweight
Conspower is a bit low. Loud without a suppressor
Just the best Co2 air rifle - period!
October 4, 2014
This may be the best air rifle on the market for a regular guys price point. I originally wanted to find the wife a gun she could not complain about. You know... this one's too hard to cock, this one's too heavy, this one feels or looks weird, etc. I determined this rifle would be the best for her needs and I was right. She loves it! Especially the easy bolt action vs. break barrel (she can't manage any of them). What surprised me was how much I enjoy it too. It surpassed all my expectations and is the most fun to shoot. Working the bolt to fire all 8 shots loaded in the cylinder in about 15 seconds is a lot of fun. However, the best attribute of this rifle is stunning accuracy. I'm talking inside a dime at 25 yds with the RWS Meisterkugeln pellets. There's certainly less power than some other rifles on the market but you won't mind when you virtually can't miss the bullseye. The only thing I'd change is the 88g CXo2 cartridge. I get well over 200 shots before the pellets begin to drop. That's a lot more time than I typically can devote in one sitting. There is of course the available adapter for $100 which will pay for itself eventually. Check out the videos and all the reviews on this fantastic rifle and then just get one. I love it.
ProsEasy to use and deadly accurate. Best stock trigger I ever tried.
Cons88g cartridges get expensive.

Great squirrel gun.
July 10, 2014
I haven't used an Airgun since I was a kid some 40 years ago. How they have changed! I read many reviews and narrowed my choice down to 3 and asked Airgun Depot support for their help in deciding the best gun for my squirrel problem. The Hammerli 850, Benjamin Discovery & the Hatsan AT-4410 all .22 cal. The other choices were great guns in their own right, but the Hammerli 850 fit my requirement for ease of use using the 88gr. CO2 cartridges and the 8 shot rotary clips. I equipped mine with a Centerpoint 4-16x44mm scope and compensator. Not only is this gun deadly accurate at 35 yards it's quite as well. This gun may not have the fastest fps rating at 650 fps, but paired with the RWS 14.5 gr lead pellets in dome, s-point or hollow point it has plenty of knock down power. Thanks for recommending the Hammerli 850 Airgun Depot!

This Gun Is Fantastic
June 12, 2014
While my more expensive PCP's spend more time traveling back and forth to AGD because of problems (thanks AGD for making the process as painless as possible), I just keep shooting, quite accurately with open sites I might add, and enjoying my 850. This gun is the Honda that sits out in the driveway while the Ferrari stays in the garage. Sits in the driveway and gets driven every day with no problems. This gun cycles smoothly, is very accurate, not to heavy, and with a couple of not to expensive items from the 850 store, I'm able to refill the used 88 gr. bottles of CO2 for about $1.50 a bottle. And with about 200+ shots per bottle, it's very inexpensive to shoot. Oh, nice crisp light trigger. Under 2lbs!

ProsWell made Cycles very smoothly Very accurate even with open sites Feels good to hold and shoot Nice light trigger 8 Shot repeater Not cocking!
ConsA bit low on the power. The 850 store can give it a bit of a boost. I have the .22 and with the boost, it will be up to about 17 FPE. Definitely a 35 yard and under gun. But that's what it is and it does it beautifully.

Very solid accurate gun
May 3, 2014
Very solid gun, also very accurate. I have used RWS Superdome and Crosman Destroyer EX pellets and my groups are about 1/2" at 30 yards (crosman is 1/2" with a couple fliers). I mounted a Tasco 4-12x44 AO scope to the gun, you may think that is a little much, but it is not. The gun out of the box is good to about 40 yards with about 2 inches of drop (sighted in to 25 yards). I installed a heavier hammer spring and now I can shoot about 50 yards with 2 inches of drop. It knocks birds right over at 30-35 yards (I even shot one at 50 yards). The trigger is adjustable and is two stage. I get about 200 shots from one 88g co2. So far I have shot about 1000 pellets through the gun and am very pleased.
ProsQuality Accuracy Feel

Excellent gu that emulates real life sniper rifles
April 13, 2014
Hammerli 850 Air magnum is an outstanding rifle to practice sport shooting. I bought the caliber .177 and have been having a lot of fun. This is the first time that I own a pellet gun and I am having a blast.
- The rifle was really well designed. The bolt mechanism is intuitive and makes you fire a lot of pellets quickly and accurately. The weight of the gun is perfect. It doesn't feel like a toy (BECAUSE IT IS NOT A TOY, FAR FROM THAT, IT IS A GUN) and its not heavy to the point of bother.
- The refurbished version has an almost invisible "R" in the receiver, which I would never find out if I haven't read another review before the rifle arrive and, otherwise, is new fully functional rifle.
- I used Ai rsource co2 cartridge/Crosman pellets and has been working fine. The accuracy is as expected and the safety makes sure no accident will happen. The sight is really nice and I have tested between 10 and 50 m. It worked really well concerning small targets (not quarter size, but the size of a phone book). At 50 m I had a target of 2 x 3 feet and the top part was marked in white to give brighter reference. I shot under extreme conditions (54F, windy and 7am in a cloudy day with low light) and still could hit the target 100% despite been barely visible from that distance. The fact that all the pellets hit the bottom part means that I should adjust the sight for longer distances, not that the gun is inaccurate. I intend to purchase a scope for this gun despite loving its sight just to make my life easier to go from close to long distances and hit quarters.
- I REALLY recommend waiting the refurbished version and of 850 air magnum. This is the first time that I shoot anything and I am confident on my aim, so should you if you buy one of these...
Pros- High quality material, design and performance. - Accuracy and speed. - Sniper design. - Relatively silent weapon. - Great sight. - Safety is very safe.

1st use review
March 13, 2014
I ordered and configured my Hammerli 850 .177/4, 5 mm based upon good reviews on this and other sites. I bought the weaver scope adapter, compensator, 2 extra magazines, 3 tins 500 each - RWS R 10 Match 177 cal/4,5mm 7g pellets and 1 pkg of 500 - RWS assorted pellets for sight-in ., 1 box of 24 88g CO2 cartridges . I also bought and had the gunsmith mount a Nikon Prostaff Target 3-9X40mm EFR scope. Everything was in fine order. I have only fired about 24 pellets through the gun at this review. Later I may do an update.
I bought the Hammerli 850 for shooting starlings and black birds that come in flocks to overwhelm my bird feeders. I was using a 22 rifle with subsonic ammo, but felt it was too much for the job.
1. Some other reviews have complained about pellets falling out of the 8 pellet rotary clip. The Hammerli manual shows how to orient the clip and insert the pellets. The clip can be laid on a flat surface with the metal center facing up. The pellets are dropped in with the hollow portion facing up i.e. the back of the pellet, then just press them down with your thumb and the inside rubber holds them in place. They won' fall out, they won't hang up in the gun and the bolt action works fine, even if it is a little tight at first. Perhaps the rubber inside the clip is a recent design improvement.
2. Another review said to screw the CO2 cartridge in until it stops to get a tight seal, that is correct, but a bright Warning was included with my gun saying: "Screw the AirSource capsule into the valve thread until the end of the cap is pierced. Continue to turn until firmly tightened and then slacken by one quarter (1/4) of a turn in order to equalize tolerances between brands of CO2 cartridge."
3. The user manual must be read so you get the latest information for your weapon.
ProsNo complaints about the gun, it feels solid to me, even a bit heavy but well balanced. Some complain about the plastic stock, but I prefer them as wood stocks can occasionally warp.. In about 1-1/2 clips I had it sighted in pretty good and shooting quarter size patterns at 50 feet or 16.6 yards/16 meters. The indoor range I belong to, was too cold and had mechanical problems with the target return or I believe I could have had dime size patterns on sight-in day. I have only positive remarks about the gun, and online advice at this time. Thank you to those who took the time to leave a review.
ConsMy "cons" are not with the weapon. This is the first pellet gun I have ever purchased and I was confused by the lack of information and the layout of some internet sites. This may be just my individual problem. 1st I wanted a scope mount, but only an adapter was offered and it mentioned Weaver. I did not know that Weaver is a standard, and since I bought a Nikon scope I didn't buy the Weaver adapter until my gunsmith told me I needed it. So that delayed everything by more than a week, plus extra shipping cost. Also, I didn't want to buy a case of 24 88g CO2 cartridges, nor pay shipping, but I found later that I could not buy them locally and then had to go back and order them from AirGun Depot, 24 for $170. This added delay and increased my costs, which removed some of the fun from the initial research and purchase. I also worried if the Air-Venturi 88g CO2 cartridges would work in my Hammerli 850, or if Hammerli (RWS? Umarex?) required a proprietary cartridge. So, for me, who knew nothing of pellet guns, to feel comfortable and not make mistakes that resulted in long delays and unexpected costs, I needed more basic and advanced information about what I was buying, why I might want it and what it would work with.

I bought mine from Airgun Depot as a refurbished unit after reading good reviews on this rifle. I'm sure glad I did!
Gun looked BRAND NEW when I received it. After mounting a scope I started testing to see which pellet it preferred. I was amazed at how many types and weights that shot accurate from it. I still haven't decided which one the gun likes the best, (I tend to stick to premium pellets and NO alloys).

ProsVery accurate and mine is not pellet fussy. Also, plenty enough power if you hunt to take rabbits and squirrels. Very quiet gun as well. Loved the fact it came with two magazines.

Perfect for Eliminating Rat Problem
December 11, 2013
This gun is great! It is exactly what I was looking for. Every shot is accurate. I was hunting rats with a Gamo Whisper Deluxe .177, but the pellets kept going through the rats giving them the opportunity to escape and die in a impossible to reach location. The Gamo is a little loud and has tons of kick. It was difficult to place the pellets at the rats' heads from a distance because of the recoil. The .22 cal Hammerli 850 solves these problems. It has no recoil, so shots are dead on every time. Also, the .22 cal pellets inflict more damage for better results. The trigger is also much better than the Gamo. I love shooting this gun.

I just got mine a week ago from Airgun Depot.. It is very very much like a real rifle!!! I also have Crosman 1077 which I still love.... (It will put holes in metal roofing from 20 feet!!! I sighted my 850 rifle in with a Center Point bore laser and my cousin fired it and tweaked the scope live. My cousin has a break barrel air gun but he was really very impressed by the Hammerli 850!!! NO noise from the gun or recoil !!!! You hear the hammer and the impact PERIOD. I got the Umarex co2 adapter from Airgun Depot and it works great. Do place the penny between the 12 gm cartridges but if you don't that is OK... the one will supply all you need but for less time as that is how co2 works!!! I got the RWS 6x42 IMR scope...awesome. UTG Dragon Claw bipod. The Umarex compensator is great with electrical tape wrapped finely from back to front and it DOES quiet the gun!!! This rifle is quite light and fun. Get all the extras and you will have a blast !!!! You will feel like a sniper that can not miss !!!!

Good bang for the buck, don't use in sunlight!
November 6, 2013
So the Hammerli 850 is a great co2 gun. Very simple to open up and clean, modifications I can see can be easily made to make it a bit more powerful and accurate. Throw a scope on it and you will be grouping very well at 30-40 yds.

My one major complaint: prone to locking up in the heat. I have difficulty with the gun over 80 degrees in the backyard and that has soured my enjoyment of it. The easy fix is to install a slightly heftier spring to make certain that the gas gets released.

Fantastic rifle
May 10, 2013
This rifle is truly amazing. Solid, well built and not too heavy. I am using RWS Meisterkugeln pellets and the accuracy is impressive. At 25-30 yards, you will always hit the bullseye. I am using Walther CO2 cartridges and you can easily shoot 30 magazines before noticing any pellet drop. Attaching a bipod on the plastic CO2 cover can be tricky, but you will not regret it.
ProsAccurate Well made 8 round magazine is great when you hunt and need that quick second shot
ConsToo much oil on the metal parts when I received it, but nothing to worry about.

The 850
October 18, 2012
When this gun shoots it is a great accurate and powerful shooter. However, it has a major design flaw. The rotary magazine does not always line up with the chamber, which limits the bolt from going forward. Also, when you pull the bolt back it can grab a pellet and drop it into the trigger housing causing the gun not to operate. They need to have the rotary magazine click into place to prevent this problem.

After only two months of use we had to send this gun back to the manufacturer because the bolt kept grabbing the pellets and dropping them into the trigger housing causing the gun not to operate. This is a major design flaw but Umarex\Hammerli does not cover it under their warranty. They call this an "operator error." The issue with this gun is that it is hard to tell when the magazine is lined up with the chamber. If it is not properly lined up the bolt can grab the pellet when you pull it back making the gun useless and in need of repair as the pellets will drop into the trigger housing. The cost for repair is $60 shipping (total both ways) and $54 for Umarex to fix the gun.
ProsGreat feel and great accuracy.
ConsMajor design flaw where pellets can fall into the trigger housing making this gun inoperable. This problem is not covered by the warranty.

I'm glad i chose this one.
I was originally trying to avoid the 88gram deal, but this gun changed that. I like the bolt and the left handed hold of this rifle. Debri can get into the action, i dropped a pellet in it, and it wouldn't close till i discovered the problem. This gun shoots and works fine. I must say i like this gun better than any at this point. Still lookng for a better solution than 88gram though.

Maybe best airgun for money yet

RWS/Hammerli 850 is quality throughout...
July 22, 2010
Simply put, this is the finest and most accurate airgun I own. With Beeman FTS 14.6 grain pellets it will print 3/8" groups at 25 yds. Probably better with a little practice and more powerful scope. I was using a 3-9x32.

The action and mechanical build exudes quality in all areas.

A couple minor complaints. The stock feels/sounds flimsy at the butt end and the magazines seem a little expensive for being plastic. I guess they are this new high tech composite but still, plastic is plastic.

I was so happy with this gun I purchased a second one.

Best value pellet gun for serious pest control!
February 10, 2010
Purchased this little 'jewel' about a year ago and it just seems to get better with time. In the past couple of weeks, I have taken out 13 House Sparrows out of 13 shots from about 25' using the .22 caliber Hobby pellets that come with the rifle. Never before have I shot with that kind of success ratio at that small a pest bird. This .22 caliber pellet rifle can also take out pesky wascal wabbits from 20 yards or less and European starlings from the same range. Use a good scope, sight it in, and I must agree with the sales video that it is highly unlikely that you will miss your target. This pellet gun is amazing, fun to shoot, and great for taking out the "Trash"! This quality RWS Hammerli 850 air rifle is a great value and worth every penny!
May 3, 2009
Plain and simple, I love this gun and the squirrels don't !!!

I am very happy with this purchase. Before purchasing this gun I had trapped and relocated over 130 squirrels away from my Mom's bird feeders. It was a pain in the butt driving them over 5 miles away so that they would not find their way back, but more would just replace them.

Now I just sting them with RWS 850, and they have a new found respect for our front yard and my Mom's Bird feeders. And I am having FUN!!

Buy the scope as well, you will not be disappointed.

Exceeded Expectations
March 2, 2009
I have/had a squirrel problem living in a space in the attic where it wasn’t accessible, even exterminators threw up their hands and decided the only way to possibly eliminate them was to trap’em at $75 an extraction.

I had a better idea, did a lot of research, (reading reviews), over the past 4 months and made the decision to (A) purchase the RWS 850 AirMagnum .22 cal, (B) to buy it from Airgun Depot, both turned out to be great decisions. I ordered the gun with a CenterPoint Adventure 3-9x50mm scope, compensator, extra magazines, pellets, and cleaning pellets, (although the RWS manual doesn’t recommend cleaning pellets). As most other reviews have noted all arrived on time packed very nicely and no damage.

Prior to my rifle arriving I borrowed a friends single shot pump .177-cal air rifle. Only a third of my shots where successful, if I missed on the first shot by the time I pumped and reloaded a pellet the squirrels had enough time to escape in a wheel chair not to mention my arm being worn out by all the pumping. When I did hit one of the little buggers it took 2 to 3 more hits to put ‘em out of their misery.

So what’s the bottom line? I love the accuracy and power of this gun! I have now shot the little rats (with good PR) from 20 to 40 yds and if your aim is good it’s one shot one kill. This comes from someone who has not fired a rifle for over 30 years. The capacity to fire rapidly with ease allows the ability to make more than one kill before the vermin run for the hills. This gun now has 11 kills in the first 4 days of arriving, which makes it more economical than the exterminator’s price.

I read complaints about the safety resetting after each shot, don’t worry about it, your thump is sitting right on top of it and it works naturally with ease. I also have had no issues with the air canister cover. I did read how someone covered the compensator for additional quietness, which I did using the cardboard from a shipping tape roll, and it does make it very neighbor friendly. I also like the CenterPoint scope no doubt increasing my ability to make use of one shot. I really like the red-green illumination. Depending on the background color of what you are shooting at it makes it easier to put the crosshairs right on your target.

Hope this helps someone not spend as much time as I did making a decision. If it’s a co2 airgun you’re looking for look no more, and look nowhere else, you won’t find it for less and AGD provided great service.

Most accurate rifle i have ever owned
February 19, 2009
This is the best gun i have ever had. Accurate, powerful, beautiful! what else could you ask for??? I have the .177 version and ive been shooting it for aboout an hour a day, using mostly RWS DIABLO's. It is lite, and most of all accurate! I shot a dime sized hole at 25 yards after sighting in my leapers 3-9x50 scope. The next thing is power! This will go through a crow no problem at 15-25 yards with wadcutters. (the bad thing about wadcutters is that they lose all there power after 15 yards, thats why i use gamo pro magnums for hunting most of the time). I am still experimenting with different kinds of pellets. And when it comes to the desighn, there are the pros and the cons. The trigger and the bolt system is amazing! Though the only thing i didnt realy dig was the hollow stock. rws cut a corner on that. Other than that, this is the best gun i have ever had!!! i would reccomend this to anybody!!! If you buy it, you wont be dissapointed!!!!!

This rifle is sweet, light accurate and powerful. Only small issue was that some of the magazines were wobbly on the indexing pin and can cause jams when cycling the bolt. Just send the bad ones back to Umarex for replacements. Mine is power modded and is an excellent hunting rig. Over all I like this rifle alot, it make CO2 fun again. There are many mod options on the net like a 9oz co2 tank or HPA conversion that make it even more fun. Enjoy

A Must Buy!!!
August 28, 2008
I just purchased the RWS 850 .22 cal version, and all i have to say is WOW!!! The accuracy on this rifle is amazing..i mounted a NC Star Red Dot Scope on it and the groups are hitting each other at 21 yds! I have a Crosman 1000, and a GAMO Varmint Hunter, and so far the RWS 850 is my favorite rifle. Not having to pump after every shot is greatI shot a squirrel this morning at about 25yds and all it took was 1 shot..the litl bugger didnt even move, this rifle is powerful. Like it was mentioned before, i had ordered 6 items and all arrive together and fast. I highly recommend this product to anyone seeking out a great rifle!

RWS 850 22
November 29, 2007
This is an amazing gun for the price. Have been shooting air guns for over 40 years. Quality and workmanship equals guns costing three times the price. Mounted an RWS 3x9x40 scope, set up for
25 yards, using beeman silver bear pellets can group pellets hitting each other standing braced against a tree. Used it today squirell hunting. Took
one at 20 yards through the heart having to shoot
left handed. This rifle is a must have for any serious
plinker, target shooter or hunter. Just remember to
only use flat, round nose or hollow point pellets.
Groups well with other brand pellets also. Gun is
also very quiet and balanced well. The sales reps
at airgundepot are so nice.
Shoot Safe,

Good air rifle
November 22, 2007
This is a nice gun. I would buy it again. Lots of mods available on the web. With RWS superdome 14.5gr pellets I am getting 600fps. With RWS 11.9gr Hobby pellets I am getting 650fps. 3 shot groups at 10 yards are under 1/2 inch. But I need a better scope.

rws 850 airmagnum .22 cal air rifle review
October 24, 2007
First, excellent service. The product came fast, on time, and most importantly in excellent working order. All accessories were also included in same package.

Second, product performed as advertised. The airmagnum exceeded my expectation. I've been around airguns since age 8 and i'm 40 now. It's accurate, powerful, fun to shoot, and reloads fast. Mounted on a Winchester 3-9x scope, it is extremely accurate.

Overall, i would definitely reccommend purchasing this product from airgundepot on-line.

This is a quality air rifle that is well engineered from end to end. Beautiful sights and very accurate without a scope. The gun packs a powerful punch because of the efficient way that the product is leaky C02...etc. The gun has impressive looks, too. It would be great if the gun had a magazine clip so that you could shoot in the semi-automatic mode (comes with a bolt action, 8 round magazine) - and it would be great if the gun were a bit lighter. However, this is a great shooter, and these are minor complaints about a superb air rifle. For the money, this air gun is HIGHLY recommended.

This rifle is one of the best rifles I have shot in a long time very accurate and powerful. Both front and rear sights are adjustable on the fly (no tools required). The bolt action is smooth for the most part; when loading a new magazine it’s a little finicky but nothing to worry about. The CO2 is advertised as getting about 400 shots but you will be lucky to get half that. All and all it’s a great gun.

February 14, 2007
i hade the crossman 1077 rifle for a while but i think it would be more at home in a in a bb war than a hunting trip.i also have the smksx78 with a silencer, a bipod and a huge ass scope, that is the best rifle i have ever owned, however i need a mulishot rifle. the 850 is truly an amazing rifle. you want my advice GET IT!!!
