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.
