What is 32-40 win?

The .32-40 Winchester is a centerfire rifle cartridge developed by Winchester in 1894 for their lever-action Model 94 rifle. It is also known as the .32 Winchester Center Fire and is a cartridge designed for hunting medium-sized game, such as deer and black bear. The .32-40 Win uses a .321 inch diameter bullet, typically weighing from 165 to 170 grains, and has a muzzle velocity of around 1,900 feet per second. While it was popular in the late 19th and early 20th centuries, it has since been largely replaced by more modern cartridges with greater power and range. However, it is still used in some vintage firearms, as well as in modern reproductions of classic lever-action rifles.
