The .22 CHeetah is essentially a Remington .308 BR (empty .308 Winchester cases[4][5]), modified to fit the .22 caliber.[6] Two custom gunmakers, Shilen Rifle Company and Wichita Engineering, made rifles specifically for the cartridge.[7] The cartridge's 50-grain .22-caliber bullets have a muzzle speed upward of 4,300 ft/s (4,250 according to some[8]), and the cartridge is known for its long-range accuracy and velocity.[2] Its high intensity is notoriously hard on barrels, which require constant cleaning.[8][9]
