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

The Underwood Ammo Xtreme Penetrator in 10mm Auto is a hard-hitting hunting and self-defense load built around a 140 gr Solid Monolithic bullet machined from solid copper. Rated for medium-large game, this round is designed for deep penetration and is equally at home on a hunt or carried for personal defense.

Pushing the bullet to a 1500 fps muzzle velocity and delivering 700 ft lbs of muzzle energy, the Xtreme Penetrator sits firmly in the supersonic class and runs cleanly in modern 10mm Auto pistols. The solid copper monolithic construction eliminates jacket-core separation, while the bullet's engineered nose profile is built for consistent terminal performance.

Each round is loaded into premium nickel-plated brass cases and assembled to tight tolerances on Underwood's production line, delivering a clean-shooting, accurate 10mm Auto load for shooters who want repeatable results from their handgun.
