10mm Auto
Handgun Cartridge



The 10mm Auto is one of the more powerful pistol cartridges on the market today. For this reason, it is one of the few pistol cartridges that is capable of efficiently taking big game animals, with proper shot placement of course. If you choose to use the 10mm for hunting applications, we would recommend using either our 180 or 200 grain JHP Sporting Handgun Pistol bullets.

Like most pistol cartridges, the 10mm headspaces on the case mouth. When loading for this cartridge, bell the case mouth just enough to reliably guide the bullet into position and then secure the bullet with a taper crimp. Using this seating and crimping technique will help ensure proper headspacing.

The S.A.A.M.I. overall cartridge lengths for this cartridge range from 1.240” min. to 1.260” max. Seating to anywhere in this range is acceptable, but there may be a depth at which your particular firearm performs the best.
