A straight-taper, rimless cartridge case in brass, Boxer primed. The 10 mm Auto cartridge was developed with the 10 mm Bren Ten automatic pistol in 1980 to 1983, by Dornaus & Dixon Enterprises (now defunct) in co-operation with Norma AB. The object was to provide a pistol round with recoil, comparable to the 0.45 ACP but with greater velocity and energy. The bullet may be hollow point or full metal jacket with lead core. The Bren Ten pistol failed, but the ballistics of the cartridge were sufficient to keep

firearms manufacturers interested. Colt eventually took the lead with its 10 mm Delta Elite, although this pistol is no longer produced. The FBI then decided upon the 10 mm as its service round. This gave it a degree of official approval, although the 10 mm was quickly supplanted by the 0.40 S&W in FBI service. The 10 mm continues in law enforcement use in the Western hemisphere, although the widespread adoption of pistols in 0.40 S&W and 0.357 Sig by numerous law enforcement agencies has caused its popularity to wane. Compatible platforms include suitably chambered Glock, SIG, Smith & Wesson, Colt and Heckler and Koch pistols, Heckler and Koch MP5/10 sub-machine gun, Steyr Tactical Machine Pistol (TMP).
