    Benefits of IGT over Spring Piston:

    • Smoother cocking

    • Functions perfectly in cold weather
    • Lasts longer than a metal spring


    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 breach. 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 Magnum!

    Mendoza also sold a repeater breakbarrel a few years back (don't think they do anymore). From what I understand, it worked pretty well, but only with wadcutters. And it wasn't that powerful! I opted for the single shot version of that gun, so I can't vouch for its usability, but let us know if the magazine system works! If I recall correctly, the Mendoza system looks (looked) much different than this GAMO one, so I have no idea if they are the same design.

    Also, what is the real power? You know, with actual lead pellets... I can't keep track of all of GAMO's pellet technology...

    I got to shoot the Gamo this morning and after the 6th shot the scope twisted, crosshairs are loose inside scope, scope tight to rings mad.gif Now what do I do?? I emailed the supplier and they said they are thinking about what to do? confused.gif
    I thought that would be a no brainer???
    The chronograph adverage on the six shots was 868 fps, St Dev 35 and spread 112.

    Pyramyd Air should know what to do U would think??

    Ok What scope should I order to take the shock of the spring?

    I would go with a Hawke scope with Dampa mounts.

    What pellet weight?

    Lots of decent scopes for springers out there. My knowledge on the subject is obsolete, unfortunately.

    I received the Gamo Swarm Magnum from Pyramyd Air and the box didn't include the 10 shot magazine. WOW Pyramyd Air I'm starting to have my doubts about customer service???? They have had my money, paid thru paypal, since April 29th 2018. I have spent a few hours and miles to just get to this point and still can't enjoy the rifle. still shaking my head

    It's common for a new airgun to diesel, this effect should subside after 20 -30 shots and ES should drop down to around 20 FPS
    My Hastsan 87 QE .22 average velocity is 715 fps with the 14.66 H&N FTT, I have not been able to get the advertised 800 fps claimed by Hastsan with a lead pellets, the lightest pellet I've tried is a RWS WC 14.0 gr and those shoot very well as do the RWS Super Dome.

    I took it out and shot 20 rounds with out the scope and then ten rounds with the scope thru my chronograph.
    On the thirty rounds the adverage fps was 704, standard deavation 122, min 306, max 858, and spread 552. The last ten with the scope the adverage fps was 849, st div 14, min 837, max 858, spread 21. this was shooting H&N Terminator 16.36 gr. pellets.

    Minimum of 306?!? I'd throw out that one. Probably misread it, unless it's point of impact also was extremely low.

    Not a bad average velocity with those heavy pellets. I'm sure it will settle down eventually. My Gamo took more than 20 rounds to quit dieseling. I'd give it more like 150... You might want to pick up a pack of the cheap Crosman pellets and just shoot cans with them for a little bit.
