Underwood Ammo 10mm Handgun Ammo - 100 Grain | Xtreme Defender

The Underwood Ammo 10mm Handgun Ammo - 100 Grain | Xtreme Defender is a high-performance ammunition designed for maximum penetration and stopping power. This ammunition is based on the popular Xtreme Penetrator product line, featuring an optimized nose flute, total weight, and velocity to achieve a penetration depth of up to 18 inches.

What sets this ammunition apart from others is the enormous permanent wound cavity (PWC) it creates. No other expanding hollow point comes close to achieving the diameter and volume of the PWC created by the Xtreme Defender. Even when shot through barriers such as wallboard, sheet metal, and automotive glass, the solid copper body ensures that the PWC remains unaffected.

The Xtreme Defender offers a PWC that is twice the size of any expanding bullet, reducing recoil and increasing effectiveness. CNC machined from solid copper, this ammunition overcomes barriers to penetration with its radial flutes that force hydraulic energy inward and build pressure. The minimal surface area increases force at the point of contact, and the sharp cutting edges effectively defeat barriers.

To enhance its functionality, the Xtreme Defender is loaded with nickel plated casings using the new Ducta-Bright 7a process. This provides several advantages, including improved feeding in all firearms, enhanced corrosion resistance, improved aesthetics, and ease of cleanup during reloading. Unlike brass casings, nickel plated casings do not tarnish during storage or when in contact with foreign materials.

Furthermore, the nickel plating in Underwood Ammo™ rounds eliminates any concerns regarding embrittlement or failure, making it safe and reliable for reloaders. The ammunition also utilizes flash suppressed powder, ensuring clear vision during low-light situations.

As with all of Underwood Ammo's products, this ammunition undergoes rigorous field testing using real firearms in real-world scenarios. If, for any reason, the ammunition fails to meet performance expectations, Underwood Ammo stands by its product and ensures customer satisfaction.

This high-performance ammunition is new production, non-corrosive, and uses boxer primed, reloadable brass cases. With a muzzle velocity of 1825 fps and muzzle energy of 740 ft. lbs., the Underwood Ammo 10mm Handgun Ammo - 100 Grain | Xtreme Defender offers superior ballistics and a penetration depth of 18 inches.
