Hornady 91224 American Gunner 10mm 155gr XTP Hollow Point Ammo

The Hornady 91224 American Gunner 10mm ammunition delivers proven stopping power with 155-grain XTP hollow point bullets engineered for consistent expansion and deep penetration. This factory-loaded ammunition combines precision manufacturing with Hornady's legendary XTP bullet design to provide reliable performance across multiple shooting applications.

What Makes This Different

The XTP (eXtreme Terminal Performance) bullet features controlled expansion technology that ensures reliable mushrooming while maintaining bullet integrity. Unlike standard hollow points that may clog or fail to expand, the XTP design incorporates precise serrations and a swaged core that promotes consistent performance across varying velocities. Factory-loaded to optimal specifications, this ammunition eliminates the guesswork of handloading while delivering match-grade consistency.

Key Features

• 155-grain XTP hollow point bullets with controlled expansion design
• Brass cases sized and inspected for consistent chambering and extraction
• Factory-loaded to SAAMI specifications for reliable ignition and pressure
• Nickel-plated cases resist corrosion and enhance feeding reliability
• Precise powder charges measured for consistent velocity and accuracy
• Boxer-primed cases suitable for reloading applications
• 20 rounds per box, 10 boxes per case (200 total rounds)

Field testing demonstrates consistent accuracy potential of 2-3 inches at 50 yards from quality firearms. The 155-grain weight provides an optimal balance between velocity and energy transfer, making it suitable for personal defense, hunting medium game, and competitive shooting. Weather-resistant primer sealing ensures reliable ignition in adverse conditions, while the nickel-plated cases reduce fouling and facilitate smooth cycling in semi-automatic platforms.
