UA 646 45ACP+P 200GR XP 20/10

The Underwood Ammo 45 ACP+P 200-grain Xtreme Penetrator round is built for shooters who prioritize deep, reliable penetration through barriers and intermediate materials. Loaded with Lehigh Defense's solid copper Xtreme Penetrator bullet, this 45 ACP+P ammunition combines Underwood's reputation for power with a projectile engineered specifically to punch through obstacles without deformation or deflection. The 200-grain bullet weight and higher pressure load make this a serious choice for defensive shooters and hunters who demand performance beyond standard commercial rounds.

The solid copper construction of the Xtreme Penetrator eliminates the jacket-and-core separation that undermines many conventional bullets, instead delivering energy through consistent, deep wound penetration. The bullet's specialized nose geometry optimizes feed reliability across platforms while maximizing penetration in tissue and barriers alike. At 1,000 feet per second, this load generates 444 foot-pounds of muzzle energy—respectable power for a 45 ACP+P platform that won't run you out of ammunition quickly on the range or in a defensive scenario.

Each box contains 20 rounds across two 10-round packs, a practical quantity for testing, defensive carry rotation, or serious practice sessions. Whether you're evaluating duty loads, working up a defensive rig, or simply exploring alternatives to traditional jacketed ammunition, the Underwood Xtreme Penetrator offers a straightforward path to deeper penetration and more predictable performance under real-world conditions.
