Underwood Ammo is known for their power and precision, and they’ve joined forces with Lehigh Defense to produce the Xtreme Penetrator line of ammunition. Lehigh’s Xtreme Penetrator is a solid copper bullet featuring a specially designed nose to maximize penetration into the target, while also feeding reliably from a magazine. The Underwood Ammo Xtreme Penetrator round hits the target hard, the unique nose increasing the hydraulic velocity inside, resulting in a massive permanent wound cavity surpassing the performance of the competition.

  • Bullet weight: 140 grains
  • Muzzle velocity: 1,500 fps
  • Muzzle energy: 700 ft/lbs
  • 20 rounds per box

Computer designed and CNC machined, the Underwood Ammo Xtreme Penetrator is great for the environment, but real bad for your target.
