The .22 CHeetah (both C and H are upper-case,[1] referring to Carmichel / Huntington[2]) is a .22 wildcat cartridge developed in the 1970s or 1980s by Jim Carmichel and Fred Huntington.[3]

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]
