Underwood 45 ACP+P ammunition with 200-grain solid copper projectiles. High-velocity +P loading delivers superior penetration for defensive and hunting applications. 20 rounds per box.
Underwood ammunition has earned a reputation for delivering performance-driven loads that exceed standard specifications. The Xtreme Penetrator line represents the pinnacle of their engineering philosophy.
The solid copper construction eliminates the jacket-core separation that can limit penetration. This monolithic design ensures consistent, deep penetration through intermediate barriers—a critical consideration for defensive ammunition. The 200-grain weight in a +P loading strikes an excellent balance between velocity and momentum, delivering the kind of terminal performance serious shooters demand.
This is ammunition for those who understand that performance matters.
