Shooting
The Crossman 622 is a .22 caliber side-action repeating pellet gun, which is fed with Crossman Super-Pells. The 622 comes with a detachable magazine, which can hold up to 6 pellets. The muzzle velocity when firing is 375 feet per second, and each .22 pellet weighs 15.5 grains. In addition to this, the Crossman 622 features both rear and front sights, and the front sights can be adjusted for elevation and wind.
Power
From 1971-1978, along with their air rifles Crossman sold CO2 cartridges, which Crossman re branded as "Powerlets". Each Powerlet can fire up to 30 rounds before a replacement cartridge has to be inserted. Failing to replace the cartridge causes jams, however, and may damage the rifle.
