Hornady XTP 10mm Auto 155gr Hollow Point Bullets - 100 Count

The Hornady XTP 10mm Auto 155-grain hollow point bullet delivers controlled expansion and deep penetration for serious defensive applications. These precision-manufactured projectiles feature Hornady's proven XTP (eXtreme Terminal Performance) design that has set the standard for hollow point bullet performance across law enforcement and civilian markets.

What Makes This Different

The XTP bullet construction uses a swaged lead core with precise jacket thickness variations to control expansion at different velocities. Unlike standard hollow points that may over-expand at high velocities or fail to expand at lower speeds, the XTP design maintains consistent performance across the 10mm's wide velocity range. The controlled expansion typically achieves 1.5x original diameter while retaining 95% of bullet weight.

Key Features

• Swaged lead core with precise jacket thickness for controlled expansion
• Deep hollow point cavity with serrated jacket edges
• 155-grain weight optimized for 10mm Auto ballistics
• .400 inch diameter with tight manufacturing tolerances
• Cannelured design improves bullet-to-case grip
• 100 bullets per box for reloading convenience
• Consistent ogive profile for reliable feeding

These bullets perform effectively across velocity ranges from 1,000 to 1,400 fps, making them suitable for both full-power 10mm loads and reduced-recoil applications. The XTP design has proven reliable in law enforcement duty ammunition and remains a popular choice for hunters pursuing medium game. Terminal ballistics testing shows consistent expansion in both bare gelatin and through heavy clothing barriers.
