The 0.32-20 Winchester is a rimmed, brass case with a slight bottleneck, Boxer or Berdan primed. A variety of bullets can be found, lead, jacketed soft point or full metal jacketed, but almost always with the nose flattened to improve terminal effects. Shot loadings have also been made in this calibre. Some loadings are 'rifle only', too heavy for use in a revolver; the specification data given below are for use in revolvers or rifles, unless otherwise indicated. This cartridge appeared in 1882 for a 0.32 calibre

Winchester lever-action rifle and was thereafter used in rifles by various makers and in revolvers made in the USA and Europe. The large cartridge case gives a useful amount of power for hand gun use, and as a rifle round it was long popular with farmers for dealing with vermin and small game. Compatible platforms include suitably chambered revolvers and sporting rifles.
