The .32-20 Winchester, also known as the .32 WCF (Winchester Center Fire), is a centerfire rifle cartridge developed by the Winchester Repeating Arms Company in the late 1800s. It was designed for use in lever-action rifles and was based on the same case as the .38-40 Winchester, but necked down to accept a smaller, .312-inch bullet.

The .32-20 Winchester cartridge typically fires a 100- or 115-grain bullet at a muzzle velocity of around 1,200 to 1,400 feet per second, delivering relatively low energy and stopping power at short to medium ranges. It was originally designed as a pistol cartridge for use in revolvers, but was also adapted for use in lever-action rifles for hunting small game such as rabbits and squirrels.

The .32-20 Winchester was a popular cartridge in the early 20th century, and was widely used by hunters and law enforcement officers due to its relatively low recoil and quiet report. However, it was eventually largely replaced by more modern cartridges with similar performance characteristics, and is now considered a relatively rare and specialized cartridge. Nonetheless, it remains popular among collectors and enthusiasts of classic firearms.

The Commission internationale permanente pour l'épreuve des armes à feu portatives ("Permanent International Commission for the Proof of Small Arms" – commonly abbreviated as C.I.P.) is an international organisation which sets standards for safety testing of firearms. (The word portatives ("portable") in the name refers to the fact the C.I.P. tests small arms almost exclusively; it is ordinarily omitted from the English translation of the name.) As of 2015, its members are the national governments of 14 countries, of which 11 are European Union member states. The C.I.P. safeguards that all firearms and ammunition sold to civilian purchasers in member states are safe for the users.
To achieve this, all such firearms are first proof tested at C.I.P. accredited Proof Houses. The same applies for cartridges; at regular intervals, cartridges are tested against the C.I.P. pressure specifications at the ammunition manufacturing plants and at C.I.P. accredited Proof Houses.
