Load data for caliber ".33 Win."
The .33 Winchester, also known as the .33 WCF (Winchester Center Fire), is a centerfire rifle cartridge developed by the Winchester Repeating Arms Company in the early 1900s. It was designed for use in lever-action rifles and was based on the same case as the .32 Winchester Special, but necked up to accept a larger, .338-inch bullet.The .33 Winchester cartridge typically fires a 200- or 225-grain bullet at a muzzle velocity of around 2,100 to 2,300 feet per second, delivering moderate energy and stopping power at medium ranges. It was designed as a hunting cartridge for use on medium to large game such as deer and elk, and it gained a reputation as an effective and versatile cartridge for hunters.
However, the .33 Winchester was not as popular as some of Winchester's other cartridges, such as the .30-30 and .38-55, and it was eventually discontinued in the mid-1930s. Nonetheless, it remains a historical and collectible cartridge, and is occasionally still used for hunting by enthusiasts of classic lever-action rifles.

C.I.P.
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.
