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.[2] It is similar in name but unrelated to the .32-20 Winchester cartridge (which is also known as .32 WCF).

[edit] History

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.[3] It was also marketed as something more powerful than the .30-30 and yet had less recoil than the .30 Army.[2][4] This new cartridge enjoyed only moderate success, and remained hampered by the small selection of available bullets in the .321 diameter.[2] 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.

[edit] Performance

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 [6]
