The Underwood Ammo 941 Xtreme Penetrator Platinum 10mm Auto 140gr Solid Monolithic round is engineered for consistent penetration and reliable feeding. Built around Lehigh Defense’s Xtreme Penetrator bullet, this load uses a solid copper projectile paired with a nickel-plated brass case to deliver repeatable performance and clean cycling.

This 10mm Auto load is well suited for hunting medium to large game and for defensive use where deep, straight-line penetration is desired. Its supersonic muzzle velocity and carefully machined nose profile help create large permanent wound channels while remaining safe for use with suppressors. Underwood Ammo’s focus on precision manufacturing and quality control results in ammunition that serious shooters trust for demanding applications.
