Hornady American Gunner 10mm 155gr XTP

Proven Performance. Every Round. Every Time.

When the stakes are high, you need ammunition you can trust without hesitation. The Hornady American Gunner 10mm Auto 155gr XTP delivers the kind of consistent, hard-hitting performance that serious shooters and self-defense carriers have relied on for decades. Loaded with Hornady's legendary eXtreme Terminal Performance (XTP) bullet, this round is engineered to perform when it matters most.

The XTP Bullet — Built for Controlled Expansion

The XTP bullet is one of the most respected projectiles in the industry, and for good reason. Its serrated cannelures control expansion across a wide range of velocities, ensuring reliable mushrooming whether you're shooting through heavy clothing or at extended handgun distances. At 155 grains, this 10mm load strikes an ideal balance between velocity, energy, and penetration — delivering deep, consistent wound channels with every shot.

American Gunner — Serious Ammo for Serious Shooters

Hornady's American Gunner line was purpose-built for the everyday shooter who demands more than bulk-pack performance. Each round is loaded to consistent, accurate specifications using select brass cases, reliable primers, and carefully measured powder charges. The result is ammunition that feeds smoothly, cycles reliably, and groups tightly — whether you're running drills at the range or carrying for personal protection.

10mm Auto — Maximum Versatility

The 10mm Auto cartridge is one of the most powerful semi-automatic pistol rounds available, offering flat trajectories and hard-hitting energy that make it equally at home in the woods as on the range. Whether you're packing a Glock 20 in bear country or competing in USPSA, this load delivers the power and precision the 10mm platform was designed for.
