Underwood Ammo Xtreme Penetrator Platinum 10mm Auto 140gr Solid Monolithic - Box or Case

The Underwood Ammo Xtreme Penetrator Platinum in 10mm Auto is a hard-hitting defensive and hunting load built around a 140 gr Solid Monolithic copper projectile. The Xtreme Penetrator is a solid-shank bullet designed for deep, straight-line penetration on tough targets, making it well suited for medium-large game and dangerous-game defense applications.

This load drives the 140-grain bullet to a muzzle velocity of 1500 fps and produces 700 ft lbs of muzzle energy from a 10mm Auto handgun. Rated Supersonic, the Xtreme Penetrator is a popular choice for hog, deer, and bear-defense scenarios where barrier penetration and energy retention matter most.

Each cartridge is loaded in nickel-plated brass cases for smoother feeding, corrosion resistance, and improved visibility in low light. This is new production ammunition from Underwood Ammo's Platinum line, packaged in a 20-round box with 10 boxes per case (200 rounds total).

Your purchase options:

• Box - 20 Rounds
• Case - 200 Rounds (10 Boxes)
