Gamo broke the mold when it released the original Swarm Maxxim, the first successful multi-shot breakbarrel in over a decade.  Now comes the Gamo Swarm Magnum the most powerful Swarm yet.

The Swarm Magnum is sure to become the definitive Swarm, taking everything shooters loved about the original and dropping in a revved-up IGT Mach 1 gas piston and Whisper Fusion technology to deliver next-level power as quietly as possible. 

Featuring some of Gamo’s best technologies, the Swarm Magnum has all the benefits of gas-pistons including easy cocking, smoother shooting, and the ability to fire in cold weather. Once shooters load up their 10-shot rotary magazine, the Magnum can spit .22 cal. pellets at speeds up to 1,300 fps, a  full 300 fps faster than the Maxxim. After every shot, simply break the barrel and the magazine automatically loads the next round into the breech.  This perfected system has been left unchanged for multiple shots as fast as you can cock the barrel.  By upgrading the suppressor system from the Whisper Maxxim to the Whisper Fusion, the Magnum benefits from Gamo’s quietest noise dampening technology to date. 

The Magnum’s stock has changed for the better as well.  Featuring a glass filled nylon synthetic thumbhole stock, the Magnum provides shooters with a comfortable hold in all-weather conditions.  Resting atop the stock is an 11mm Dovetail Recoil Reducing Rail System (RRR), designed to reduce recoil stress on your included 3-9x40 scope.  For crisp trigger pulls, the Magnum features Gamo’s Custom Action Trigger (CAT), an independently adjustable 2-stage trigger.

If you want the most powerful, most quiet version of this revolutionary multi-shot breakbarrel available, choose the Swarm Magnum!

Things I liked: This rifle has very good knock down power and very accurate but I upgraded to a different scope the scope that comes on it is good quality but not top notch and I definitely like to trigger pull and it will take out up to Raccoon size game with no effort with the h&n Hornet pellets or the copper spits kugels

Things I would have changed: The only thing I would change on this rifle is put a better quality suppressor

What others should know: If you're a small game hunter and on a budget this is a perfect rifle and it's not very heavy to carry around out in the woods and does have plenty of knock-down however to take any small game

Things I liked: I like everything about the rifle especially the ten round magazine, but the scope was a little disappointing.. very accurate, powerful and light weight! Worth buying for the money!

Things I would have changed: I would rather have a removable suppressor but I guess it has to be permanent to be legal. I did change to a different scope .

What others should know: Like any other air rifle, you have to shoot quite a few rounds thru it before it settles down to group...

  • Jeff from USA asked:

    I just purchased the Swarm Magnum. Now that everyone has had a chance to shoot this gun quite a bit....what are the best all around pellets I should buy for accuracy and still have fairly good velocity???

    • Tyler from USA:

      Best luck I had with mine was Predator GTO pellets and JSB 18.13 grain, though the heavier pellets are not as consistent as the GTOs for some reason....must have a barrel that just likes them a lot

  • Jason from USA asked:

    Can you use any brand of .22 pellets with this gun? Like the Crosman Premier destroyers?

    • Tyler from USA:

      Crosman Destroyers should be just fine in this rifle. Not all pellets will fit the magazine though, so keep in mind that the longer pellets pay not fit

  • Tom from USA asked:

    I know the magnum is new in 22 cal but i own a bone collector .177 cal for three yrs and it is as good now as it was when I got it. How as the maxxim 10 shot repeater held up to the uses over time.

    • Tyler from USA:

      Have yet to have any issues with mine, had the gun since it came out
