The Underwood Ammo 243 XTP 10mm 180gr Jacketed Hollow Point offers a high-performance defensive and hunting load built around Hornady’s proven XTP bullet. Each round uses a 180 grain jacketed hollow point seated in a nickel-plated brass case, delivering consistent feeding, deep penetration, and controlled expansion at listed muzzle velocities around 1300 feet per second.

This 10mm Auto load is well suited for personal protection, duty carry, and medium game hunting where reliable terminal performance is essential. Flash suppressed powder helps preserve sight picture in low light, while non-corrosive, boxer-primed cases make the ammunition reloadable for extended training use at the range. Underwood Ammo is known for carefully engineered, real-world tested ammunition that balances power, accuracy, and dependable function.
