The .22 long rifle, also known as the .22 LR or 5.7×15mmR,[4][5] is a type of .22 caliber rimfire ammunition from the United States. It is used in a wide range of firearms including rifles, pistols, revolvers, and submachine guns.
Despite being called "long rifle", the cartridge is actually one of the smallest calibers actively made by factories today.
