.22 Long is a variety of .22 caliber rimfire ammunition. It has the same case length as the .22 Long Rifle, but differs in that the Long Rifle has a longer overall length (the length including the bullet) and a significantly heavier bullet. The .22 Long is essentially obsolete; no new firearms are designed specifically to use it. Many .22 Long Rifle guns will chamber and fire the shorter round, though the .22 Long may not generate sufficient energy to operate semiautomatic guns. The one prominent survivor of the .22 Long is the .22 CB Long, a Long cased version of the .22 CB.
