The .32-20 Winchester / 7.94x33mmR, also known as .32 WCF (Winchester center fire), was the first small-game lever-action intermediate cartridge that Winchester produced.[4] It was initially introduced as a black-powder cartridge in 1882 for small-game, varmint hunting, and deer.[5][6] Colt produced a single-action revolver chambered for this cartridge a few years later.[7]
The name .32-20 refers to the 32 caliber bullet of .312-inch-diameter (7.9 mm) and standard black-powder charge of 20 grains (1.3 g).
