The .32 Winchester Special / 8.2x51mmR (or .32 WS) is a rimmed cartridge created in October 1898 for use in the Winchester Model 94 lever-action rifle.{{cite book

History

The .32 Winchester Special cartridge, like the .30-30 Winchester cartridge of 1895, is necked down from the .38-55 Winchester cartridge of 1884. The .32 Winchester Special (.321 in) differs from the .30-30 Winchester (.308 in) 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.{{cite book | orig-year = 1965

The ''.32 WS'' cartridge

Performance

Ballistics are similar to the .30-30 cartridge and its .308 caliber (7.62 mm) 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 has a greater sectional density, and correspondingly greater penetration. According to Winchester's original claims, the .32 WS has 5-10% more energy than the .30-30 at close ranges, and less at longer ranges due to increased drag due to the .321's greater diameter and reduced sectional density.
