Badass gun with crazy powa

Pros
Incredibly strong and amazing consistent shot. I hit coins from ab 30yds repetitively. Scope is amazing cant ask for more. Not too heavy in weight but its hard to break just fyi. No weaks. Workout before buying this gun deadass.

Cons
Could be hard for some to break especially if shooting for a while so get strong lol. But its not a con cuz the gun is a beast.

This is my second rifle, and both of which have extreme lead buildup in the barrel making it almost useless to shoot accurately. I’ve tried multiple different pellets, all with the same outcome.

Pros
Good sight, pretty easy to cock.

Cons
Barrel design.

I have the Gamo magnum in .22 cal. This gun is a beast! The included scope is nice, but I replaced it with a Leapers 4-16X50 AO 36 color reticle with mil-dots. My longest shot so far is 98 yards and it makes a loud and clear smack on contact. I suggest a range finder for long shots to make better use of my mil-dots. The Gamo red fire 15.4 grain pellets are a killer in this gun. My second go to pellets are the H&N Terminator 16.36 grain. For short distance hunting, I use the H&N Baracuda match at 21.14 grain. I dropped a beaver at 30 yards with no problem. This is a man's toy here and not for the weak. Cocking force is right at 51 pounds and not meant for plinking unless you like to feel the burn from repeated cocking. My lowest FPE was 23.26 with the Baracuda match. I get 28.31 FPE with the RWS Hobby weighting in at 11.9 grain. This is not your average hunting rifle. I suggest a higher magnification on your scope because this rifle really reaches out and touch things. I was thinking of going up to a .25 cal, but there is no need if you use the right pellets in this monster. I am very impressed and pleased with this rifle.

Pros
Ultra magnum power, well built, light weight and in my opinion,, the ultimate .22 cal in it's price range.

Cons
Loud, very loud and very hard to cock ( but necessary for he amount of power produced). No silencer.

It's so powerful it ruined the scope in less than reason weeks. It's over 27 fpe. It's easy to handle. Solidly built. The sights are very nice. At 25 yards I made tight groups. H&N Terminator and Crow Magnum pellets did great. I bought mine refurbished. It's a bit loud. Mine is 22 caliber. Most pellets do well in the rifle that I have tried. Great for hunting

Pros
Light enough to take hunting. Accurate and powerful

Cons
Very much muscle necessary to break the barrel open!

Received my Gamo Magnum .22 four days ago, and I must say that I am thus far, VERY HAPPY with the purchase and quite surprised as well. I am at this point in my life literally addicted to air gun shooting, which at the age of 55 is like a second child hood for me, with the exception now that I can afford to pick and choose what I like purchase. This is now the 5th air rifle purchase that I have made within the past year and a half. I have been lucky thus far and pleased with all of my prior purchases, yet this Gamo, the second Gamo rifle of those purchases takes the cake in a lot of areas. The ergonomics of this rifle are amazing, very comfortable feel and weight to it, in all honesty, I was hesitant on getting a rifle with a thumb hole/pistol grip stock variation, I am amazed and surprised on the overall comfort and functionality of such a design. The polymer stock is ideal for toting around in my Mule to drive into my pasture, walking the fence line or running through the brush. Easy to maintain and no need worry about scratching up a nice wood finish. The power of this air rifle is very impressive. I did not bother to mount the supplied scope to the rifle, yet put on a 4x Center Point scope for the break in period. Within 25 shots, had it zeroed in at 30 yards. My incentive and reason I had gotten back into shooting air rifles simple was a result of my raising cattle and need for eliminating Feral creatures around my cow pasture. Within my area, there are feral goats, pigs, cats and dogs, not to mention Myna Birds, Rats and the over abundant Feral Chickens. Although I have just received the air rifle, have not run even a 100 rounds through it, broken in the air rifle nor learned its strengths and weaknesses, I did manage thus far to nail a feral rooster at 50 yards dropping it where it stood. This air rifle from what I have seen thus far, likes the 15.5- 18gr variation of pellets best. I like many others, have pretty much bough just about every .22 pellet currently available, with some worth their weight in gold and some just plain useless. Thus far I have gotten very promising results with the H&N Crow magnums, Gamo Red Fire and Crossman Pirahna's. Just a word of caution, particularly for those which are VERY concerned with a loud discharge because of neighbors or in urban areas... do not fire Alloy pellets in this air rifle. I fired a Gamo Luxor Alloy pellet in this thing, it cracked and sounded like firing a .22 LR or Magnum rim fire rifle. Surprised me, hell even laughed and did it a few more times, yet I live in a VERY RURAL area and could give a rip, for those living within a city.. well more than likely someones neighbor is going to be calling the SWAT team on you. The cocking effort is stiff, yet nothing a healthy individual cannot manage or do consistently for a plinking session. You can tell it is a serious system do to the increased difficulty of cocking compared to my Benjamin Jim Shockey air rifle, yet nothing to make anyone just wanna give up on it. Damn glad I made the purchase thus far, will mount a bona fide scope on it within a month, the amount of shooting I do daily, should have it broken in within a month.

Pros
Extremely powerful break barrel Air rifle, the ergonomics are very good and the trigger is just right, even with factory settings at 3.3 lbs.

Cons
Thus far I can detect none yet. The only complaint at this point is that with a rifle of this power, the intent that the manufacture has put it out for, is to why they did not mounts studs for a sling? seriously. Over came this with purchasing the Gamo sling buddy, yet a let down compared to my Benjamin air rifles with bona fide sling mounts on it. Important feature while busting through the bushes or disposing of feral creatures. I have read in some reviews that this rifle chews up scopes, am thus far NOT impressed with thee Gamo rail set up for scopes, stop pins and so forth. Will of course monitor the situation of the scope during brake in period.

Got the Gamo magnum in .22 from Airgun Depot (it arrived a day ahead of schedule, too) and I have to say: if you intend to shoot this beast a lot, you're going to end up with arms like Lou Ferrigno (the Hulk from the old TV series, if you didn't know.) Cocking this baby is, to put it mildly, an exercise in, well, exercise. This is the only air rifle that I have to cock by using BOTH hands on the barrel. Now....as far as performance and so on: It seems to digest the .22 Gamo Rocket pellets quite well, but I couldn't get much of a grouping because of the insanely unstable homemade tripod I cobbled together; when I could get a stable rest, it seemed to do a good job of putting the shots on the crosshairs for the most part. The CAT (Custom Action Trigger) was pre-set at the factory with not a hell of a lot of first-stage travel, so it was nice to be able to adjust that; the second stage is literally "right there" when you (gently!) squeeze through the small first-stage part of the pull, and the second stage breaks like glass---a VERY crisp trigger break. Very nice. The only "meh" part is with the scope: it doesn't seem to be as nice and sharp as the box scopes that have come with my two Benjamins, but that's about my biggest concern---and scopes are replaceable, after all. Plenty of power, that's for sure: it's said to be 200fps faster than my Benjamin Trail NP2 of the same caliber, and "Fat Albert" (my name for my Benjamin) has no problem punking out trash pandas (raccoons) with the Gamo Rockets, so the Magnum will undoubtedly be a fine performer too---and at about two pounds less than the Benjamin. Hey-hey-hey!

Pros
Good power, not grotesquely heavy, not terribly noisy, good accuracy (better accuracy with a good tripod, because I believe in cheating and taking as much of the human factor out of shooting as I can. Besides, if it was good enough for Colonel Sebastian Moran in "Sherlock Holmes: A Game of Shadows", then it's good enough for me.)

Cons
You pay for the extra power by having to work like a Government mule cocking this beast, but them's the breaks. As a wise man once said, "Suck it up, Soldier!"

I have the Gamo Air Magnum in .177. This rifle is extremely accurate and hard hitting, consistently grouping in the bullseye of my target set at 35 yards. I have tried many different pellets, and so far have obtained the best results with Crosman Premier Magnum Domed Pellets 10.5 grains and H&N Barracuda Match Domed 10.65 grains. Gamo Rockets, which are typically my favorite.177 pellets, do not perform well in this rifle because any pellet under 10.5 grains tend to fire at supersonic velocities.

Pros
The rifle is very accurate, once broken in, and hits very hard.

Cons
The iron sights are a little hard to get a sight picture with and the optics, while good for a combo kit, could be upgraded to match the quality of the rifle.

I have a gamo hunter extreme in .177 and it is a lot heavier than this gun. The thumbhole stock is very nice and different from my other gun. Like the extra knockdown power of the .22

Pros
Stated above

Cons

and they refuse to sell them to me unless I have an FFL license. A Federal Firearms License for some O-rings when I can buy an entire air rifle at Air Gun Depot without one? In effect, no replacement parts are available in the US through Gamo for their air rifles.

Cons
No replacements seals, springs or pistons available through GamoUSA

What is fps

asked Allen from USA

Meanings: feet per second (fps); foot pound energy (fpe); grams (g); grains (gr); FJB# (F^4 = 450,436.67979003). These are variables to calculate the efficiency of the output of a gun. The objective is to reach a velocity in fps that will give you the best accuracy AND power combination for hunting and plinking that will equate to the same wind push effect at 10 miles per hour (MPH) as the trajectory drop at 100 yards (yds.) then you just guestimate the range, drop, and windage effect to no more than a 45 degree angle offset from target for a quick shot; else, you got a lot of calculations to do such as trigonometric functions, air drag coefficients, which varies from the square of the velocity up to the knee of the sound barrier to the cube of the velocity at the peak of the sound barrier then it starts to drop down past the speed of sound, but then your pellet slows down and the coefficient of air drag is back at the cube of the velocity then drops below the knee of the speed of sound to the square of the velocity; in other words, stay at, or below the knee of the speed of sound, which is 78.1% Mach1 at 26 degree Celsius; thereafter, you can increase the velocity by 2 fps for every degree Celsius increase in ambient temperature, and vice-versa. In short form, get yourself a chronograph and on a break-barrel, increase or decrease the pellet weight until you get no more than 1.7529 fpe per grain of your pellet's mass. There you will have attained the BEST combination of accuracy and power, which can be looked at like a teeter-totter, as power goes up, accuracy goes down and vice-versa. Numbers do not lie, but you can lie with numbers, and the laws of physics are not just really good ideas.

asked Gabriel

Initial .22 caliber Magnum Accuracy:... This is my first airgun..., never shot a break barrel before.... Using .22 Gamo Hunter pellets, some pellets seem to fit great, others are nicely snug, some are 'fall out loose', others are so tight they won't load without extraordinary measures... (I've set these aside). 1) Is this kind of variation of "loading the pellet tightness" normal? 2) Should I discard the 'fall out loose' pellets or the others super tight pellets? 3) After about 50 shots, I'm getting group size of a medium apple / orange... is that group size normal considering new gun after 50 shots? 4) Can I expect improvement with the hunter pellets or should I go for a different pellet?

asked William Marker

I'm trying to balance pellet weight and pellet speed to obtain the highest FPE on target. I am the proud owner of the gamo magnum in .22 cal. The H&N hollow point lights at 12.65 grain, gives me good speed, good accuracy, but my concern is FPE down range due to the light weight of the pellets. I use the H&N baracuda match (21.14 grain ) for 20 to 30 yard shots. I'd like to find a good pellet weight for 50 to 60 yard shots that will give me the max FPE on target. All suggestions and advice is welcome. Thank you in advance.
