Underwood Extreme Terminal Performance 10mm Auto Ammunition 200 Grain Jacketed Hollow Point – 246

Underwood Ammo's 10mm Auto ammunition featuring the Extreme Terminal Performance (XTP) bullet, renowned for its unparalleled power and precision. This innovative round combines the deep terminal penetration and controlled expansion capabilities of the XTP bullets with Underwood's meticulously formulated design, resulting in lethal efficiency suited for both hunting and self-defense applications. Nickel-plated brass casings enhance feeding, improve corrosion resistance, and simplify reloading—a feature ensuring your ammunition maintains its quality even in challenging storage conditions.

Features and Specifications:

  • Bullet Design: Incorporates Hornady's XTP bullets for deep penetration and controlled expansion.
  • Nickel-Plated Casings: Enhances feeding reliability and prevents corrosion, tarnish, and simplifies cleanup.
  • Powder Formulation: Uses flash suppressed powder to preserve vision in low-light situations.
  • Versatile Use: Ideal for both hunting and self-defense applications.
  • Reloadable Components: Boxer primed and non-corrosive for reliable reloading operations.

The design focuses on delivering exceptional stopping power and reliable terminal effects, providing confidence in scenarios where effectiveness is critical. Given its high performance, this ammunition is well-suited for various firearms that can chamber the 10mm Auto, enhancing versatility across sporting and defensive contexts.

History and Development

The 10mm Auto cartridge, developed in the early 1980s, represents a powerful standard in semi-automatic pistol ammunition.
