The .22 Extra Long is a .22 in (5.6 mm) American rimfire rifle and handgun cartridge.
Background
[edit]Introduced in 1880,[1] the .22 Extra Long was used in Remington, Ballard, Wesson, Stevens, and later (1916) models of Winchester's M1902 and M1904 single-shot bolt-action rifles,[2] as well as in Smith & Wesson revolvers.[2]
Using the same 40 gr (2.6 g) outside-lubricated bullet later adapted for the much more common .22 Long Rifle,[2] the Extra Long was loaded with 6 gr (389 mg) of black powder.[2] Originally, it slightly outperformed the .22 LR, but was "not noted for great accuracy",[2] while later smokeless loads achieved about the same muzzle velocity as the .22 LR.[citation needed]
As with the .22 Winchester Automatic[3] and .22 Remington Automatic,[4] the .22 Extra Long will not chamber correctly in .22 Long Rifle weapons.[2] Because it is very dimensionally-similar, however, the shorter .22 Short, .22 Long, and .22 LR will chamber in weapons designed for it[2] (in the same way a .38 Special cartridge can be loaded into a .357 Magnum revolver, or a .44 Special cartridge can be loaded into a .44 Magnum) revolver.[citation needed]
The power of the .22 Extra Long is comparable to the standard velocity .22 Long Rifle,[2] which is much more commonly chambered and sold.[citation needed]
The .22 Extra Long ceased to be offered commercially in 1935.[2]
