The Underwood Ammo 232 XTP 10mm 155gr Jacketed Hollow Point is a high-performance handgun load built around Hornady’s proven XTP bullet. Each round uses a 155-grain jacketed hollow point projectile paired with nickel-plated brass cases to deliver consistent feeding, reliable expansion, and deep penetration. With a listed muzzle velocity of 1,500 feet per second and muzzle energy of 775 foot-pounds, this 10mm Auto load is engineered for serious performance while maintaining controllable recoil in modern pistols.

This ammunition is well suited for personal protection and medium-game hunting, as well as dedicated training and range use with your 10mm sidearm. Flash-suppressed powder helps preserve sight picture in low-light environments, and the non-corrosive, reloadable nickel-plated brass cases support long-term storage and easy cleanup. Underwood Ammo’s focus on real-world testing and carefully formulated loads underscores the brand’s reputation for precision, reliability, and thoughtful engineering.
