Underwood Ammo 10mm 180gr XTP JHP - 20 Rounds Per Box

The Underwood Ammo 10mm 180gr XTP delivers maximum stopping power through Hornady's proven XTP (eXtreme Terminal Performance) bullet design. This premium jacketed hollow point ammunition transforms the 10mm Auto cartridge into a formidable defensive and hunting round capable of taking down medium-sized game while providing reliable expansion in defensive scenarios.

What Makes This Different

Underwood's loading philosophy pushes the 10mm to its full potential, generating velocities that standard manufacturers rarely achieve. The 180-grain XTP bullet expands reliably across a wide velocity range while maintaining structural integrity for deep penetration. This combination of controlled expansion and weight retention makes it superior to lighter, faster bullets that may fragment or fail to reach vital organs.

Key Features

• Hornady XTP 180-grain jacketed hollow point bullet for controlled expansion
• High-velocity loading maximizes the 10mm Auto's ballistic potential
• Nickel-plated brass cases resist corrosion and aid extraction
• Flash-suppressed powder reduces muzzle flash in low-light conditions
• Consistent powder charges ensure shot-to-shot velocity uniformity
• Premium components including CCI primers for reliable ignition
• Compatible with all 10mm Auto firearms including Glock, 1911, and revolvers

Field performance demonstrates the effectiveness of this loading across multiple applications. Law enforcement agencies favor the 180-grain weight for its balance of expansion and penetration through barriers. Hunters appreciate the bullet's ability to anchor wild boar and deer-sized game with proper shot placement. The nickel-plated cases cycle smoothly through semi-automatic pistols while providing the corrosion resistance needed for duty carry.
