10mm Ammunition

10mm ammo (10×25mm, officially designated as "10 mm Auto" by C.I.P. and "10mm Automatic" by SAAMI) is a high-powered semi-automatic pistol cartridge developed by Jeff Cooper and introduced in 1983 with the Bren Ten pistol. Designed to deliver greater velocity, energy, and penetration than standard handgun rounds, 10mm ammunition quickly became a favorite among law enforcement, hunters, and civilian shooters. Its versatility makes it ideal for self-defense, big-game hunting, and range training.
