.22 Winchester Centerfire (.22 WCF) / 5.8x35mmR is a small centerfire intermediate cartridge introduced in 1885 for use in the Winchester Model 1885 single-shot rifle.
Factory manufacture of ammunition was discontinued in 1936.
The .22 WCF was loaded with a 45 grain bullet with a muzzle velocity of about 1550 feet per second, similar to the performance of the .22 Winchester Rimfire (.22 WRF) designed in 1890.
[2][3][4][5] Experimentation with the .22 WCF among civilian wildcatters and the U.S. military at Springfield Armory in the 1920s led to the development of the .22 Hornet cartridge.
