Load data for caliber "10 mm Auto"
The 10mm Auto is a pistol cartridge developed by Jeff Cooper and introduced in 1983 by the ammunition manufacturer, Norma. It was originally designed as a high-performance cartridge for the FBI, which sought a round that would offer improved penetration and stopping power over the 9mm Luger.The 10mm Auto uses a rimless, straight-walled case with a bullet diameter of 10.16mm (0.400 inches) and a maximum case length of 25.4mm (1.00 inch). It typically fires a 180-grain bullet at a muzzle velocity of around 1,200 feet per second, delivering high energy and good accuracy at medium to long ranges.
Despite its promising performance, the 10mm Auto struggled to gain widespread popularity in its early years, as many shooters found the recoil too harsh and the ammunition too expensive. However, in recent years, the cartridge has enjoyed a resurgence in popularity, with many shooters and law enforcement agencies turning to the 10mm for its excellent performance in both self-defense and hunting applications.

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.
