The .22 CHeetah is essentially a Remington 308 BR, modified to fit the 22 caliber.[4] Two custom gunmakers, Shilen Rifle Company and Wichita Engineering, are now making rifles specifically for the cartridge.[5] The cartridge's 50-grain .22-caliber bullets have a muzzle speed upward of 4,300 ft/s (4,250 according to some[6]), 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.[6][7]
