.22 Extra Long

Introduced around 1880, 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,[1] as well as in Smith & Wesson revolvers.[1]

Using the same 40 gr (2.6 g) outside-lubricated bullet later adapted for the much more common .22 Long Rifle,[1] the Extra Long was loaded with 6 gr (389 mg) of black powder.[1] Originally, it slightly outperformed the .22 LR, but was "not noted for great accuracy",[1] while later smokeless loads achieved about the same muzzle velocity as the .22 LR.

As with the .22 Winchester Automatic[2] and .22 Remington Automatic,[3] the .22 Extra Long will not chamber correctly in .22 Long Rifle weapons.[1] Because it is very dimensionally-similar, however, the shorter .22 Short, .22 Long, and .22 LR will chamber in weapons designed for it[1] (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.

The power of the .22 Extra Long is comparable to the standard velocity .22 Long Rifle,[1] which is much more commonly chambered and sold.

The .22 Extra Long ceased to be offered commercially in 1935.[1]
