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.
The original Winchester factory load consisted of a 300-grain (19 g) bullet at 1,420 ft/s (430 m/s) or a 330-grain (21 g) bullet at 1,380 ft/s (420 m/s).
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.
Besides the Winchester 1895 lever-action, the .40-72 Winchester was chambered in the Winchester 1885 single-shot rifle.
