The .32 Winchester Special (or .32 WS) is a rimmed cartridge created in October 1901 for use in the Winchester Model 94 lever-action rifle. It is similar in name but unrelated to the .32-20 Winchester cartridge (which is also known as .32 WCF).
.32 Winchester Special
This cartridge is based on the .30-30 Winchester cartridge of 1895, but differs from the .30-30 in bullet diameter. More significantly, Winchester decreased the rate of rifling twist in their Model 94 rifle, from 1:12 when chambered for the .30-30 to 1:16 when chambered for the .32 Winchester Special. Winchester used the slower twist to reduce fouling retention when creating a new cartridge for sportsmen who wanted to reload their own ammunition using black powder and cast bullets. It was also marketed as something more powerful than the .30-30 and yet had less recoil than the .30 Army. This new cartridge enjoyed only moderate success, and remained hampered by the small selection of available bullets in the .321 diameter. There is a wide selection of bullet types and weights for the .30-30, while the only commonly-available bullets in .321 diameter are 170 grain and 165 grain. Also, due to slow twist of barrel, accuracy suffered when barrel exhibited some wear.

Ballistics are similar to the .30-30 cartridge and its .308 caliber (7.62mm) bullet, but the larger diameter .321 (8.15 mm) bullet of the .32 WS will create a larger wound. However, given the same weight of bullet in both calibers, the .30 caliber would have a greater
