10mm Auto

Ideal for hunting game at medium range and well-suited for tactical defense, the 10mm Automatic packs exceptional power that rivals the average .357 Magnum round, providing the shooter with a greater range and flatter flight trajectory. Often known as a caliber with a niche following, the 10mm Automatic remains the choice caliber amongst several U.S. law enforcement agencies.

Drawn from American-made premium brass cups, each casing undergoes rigorous in-line and post-production quality assurance testing to ensure a flawless casing of unparalleled durability and dependability.

Standard casing dimensions and tolerances have been modified to achieve maximum performance. Jagemann™ Technologies’ in-house tooling and engineering capabilities provide the ability to customize casing dimensions for use with specific projectiles. If you have a custom request, we will meet your needs.
