The .40-72 Winchester, also known as .40-72 WCF is a centerfire straight-walled rifle cartridge designed for black powder rather than smokeless powder.

It was introduced in 1895 for the Winchester 1895 lever-action rifle.

[1] With the introduction of superior cartridges designed for smokeless powder, the .40-72 Winchester became obsolete and was soon dropped from production.

Production of loaded cartridges by Winchester ceased in 1936.
