Gamo Swarm Magnum 10X GEN3i, .22 cal

Pros
First - the service here is excellent. My third Gamo rifle, very powerful, 1 inch group right out of the box.

Cons
Magazine will not work with all shape pellets. Short skirt pellets fall out when cocking.

The magazine is nice your not dropping pellets everywhere and have not had any problems with cocking. The first time was a bit more then expected but after you get a comfortable position to break it you really do not feel the extra 11 lbs of pull.

Pros
I really like gamo air rifles this is my second one in .22 cal. The velocity is awesome.

Cons
The scope should had been upgraded to 100 yards.

Don't try to get away with cheap pellets that have no QC when made. Buy the good stuff and save a lot of time and money.

Pros
Overall nice. This will be one year I have owned this rifle. Last fall it was used for squirrel season. You must find the right pellet for the rifle. Like my .22 rimfires, only one type of ammo works. The same with this Gamo, find the pellet that works, than learn about it at the range. This fall I will be out with my Gamo for squirrels.

Cons
Nothing

I have the first generation of this in .22, and it is very close to the favorite rifle in my stable. It hits hard, is accurate, and is also surprisingly friendly to cock and relaxing to shoot an extended session with on the range. Because Gamo kept the weight down, it is also good in the woods, as it is relatively light for something with this quantity of smack. Smack it has. Great whomping beat-down power. Throw a heavy pellet in it, and it will trash your metal targets. For all that, it's quiet, or at least as quiet as you can make artillery. It's long. If you care for a carbine, you won't find it to your taste. I put the $9.95 search it on the internet trigger screw kit in, and spent an afternoon dialing it in. The trigger went from pretty good to outstanding. I have a short plateau followed by a clear wall, with a nice break at under two pounds. For the price on these, you cannot go far wrong. I haven't shot one in .177, but I hope to soon.

Pros
My go-to break barrel. They checked all the boxes. Very nice mag system.

Cons
Very little. A Picatinny rail as standard would be nice.

Changing the loading mechanism and magazine were really not necessary since the one i removed was okay. The new magazine Gamo sent in .177 had the word "updated" on the package but I could not see any difference unless the o ring and spring tension have been modified to better hold the pellets and stop the next pellet from jumping up following the recoil of the preceding shot. Be aware that the high 1200 plus fps ability of this rifle will break the sound barrier and cause a loud crack sound and loss of pellet accuracy. Recommend using above 8gr or heavier pellets in .177 to prevent this.

Pros
High velocity, comfortable stock, overall quality for price

Cons
Magazine and loading mechanism require more work by Gamo or at least better information on loading technique specifically: 1. Caution on inserting pellets in magazine because an o ring is used to hold the pellet in place and certain pellet skirts are held better than others. Pellets will fall out of magazine if pushed in too far. Pellets will raise up in magazine after firing on occasion so prior to breaking the barrel you must ensure next pellet has not jumped from proper seated position. The is a technique required to break the barrel to stop pellets from falling out. I place the end of the stock on my left leg with the rifle at about 45 to 60 degree angle then as I am closing the barrel I start to lower the barrel to nearly level. This method stops the pellet from falling out of the magazine which might happen if you kept the barrel tilted up throughout the process. The problem with the pellets falling out is known by Gamo, I changed the loading mechanism and a new magazine.

This is an adult level weapon, not suitable for pre-teens. needs swivel mounts and shoulder strap to relieve the weight issue (at ready-position).

Pros
Looks; it looks very nice; like the magazine clip feature

Cons
Heavy; Difficult to charge the weapon by pre-teens. Muzzle tip is too close to the shooters head when trying to cycle the barrel with the butt on the ground to stabilize the weapon; Scope is difficult to sight in, way off on initial attempts to zero weapon.

Also the swarm inserts the pellets to far in ,This reduces the velocity. Compared to a seated pellet... If u manually seat a pellet ,You will see and hear the increase power....

Pros
If you load pellets that have a coke bottle shape ,they will fall out..You need to use pellets that are more like a slug.That allows the band in the magazine to hold the pellet....

Cons
They should make a larger band in the magazine. This would hold the pellets better.

If target shooting is your primary purpose the cocking on this will be a workout, love the power this has though!

Pros
I bought the .22 cal. to use on squirrels and rabbits around the house. I'll also be using it for target shooting. I upgraded my scope to the BSA Optics Outlook Illuminated Mil-Dot Reticle Air Rifle Scope with Adjustable Objective, Black, 4-12x44mm (AIR4-12X44AOIRTB). Nothing was wrong with the scope that came with it, just wanted to upgrade. After firing it at paper to sight in the scope....took five shots...I fired it at a wooden 6x6 post 25 yards away. The pellets penetrated a good 1/2" (1/4" of wood showing behind the embedded pellet}. I'm confident this is indeed powerful enough for varmints. It took me five shots to sight it in because I had to familiarize myself with the reverse recoil...you gotta hold your sight picture after you pull the trigger and it does have a bit more recoil than a .22 rimfire, I'd say it compares to a .556 AR-15. It's a bear to cock...not something I'd recommend for a child and to be sexist, for a woman either.

Cons
The muzzle brake/compensator is a hollow plastic tube...worthless for anything except mounting the front sight. I will be removing and machining a functional metal replacement and remounting the front sight. The cheek rest is non-adjustable which is too bad as I would prefer it were.

I would never recommend this gun to anyone.

Pros
Good scope

Cons
I bought this gun which worked fine for the first fifty rounds or so. After that it consistently failed to load the pellets. I returned it and Gamo sent me another Gamo SM10X Gen. 2 rifle which did exactly as the first. I notified Gamo of the problem and this time got no response whatever. I'm not a novice shooter having hunted and shot recreationally for years. I had to take out the magazine in order to be confident that the rifle would shoot something. I now have an expensive and pretty ordinary pellet gun.
