Load data for caliber ".243 Win."
The .243 Winchester is a popular centerfire rifle cartridge that was introduced in 1955 by the Winchester Repeating Arms Company. It is based on the .308 Winchester cartridge case, necked down to accept a smaller, 6mm bullet.

The .243 Winchester cartridge typically fires a 55-105 grain bullet at a muzzle velocity of around 2,700 to 3,200 feet per second, depending on the bullet weight and powder charge. It is a versatile cartridge that is well-suited for hunting varmints and small game, as well as larger game such as deer and antelope, especially at medium ranges.

The .243 Winchester is a popular choice among hunters and target shooters due to its flat trajectory, mild recoil, and excellent accuracy. It is widely available in both factory-loaded ammunition and in reloading components, making it a convenient and flexible choice for a wide range of shooting applications.

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.
