Underwood Ammo combines its power and precision with Lehigh Defense Xtreme Penetrator bullets. This round is solid copper and features a unique nose that maximizes penetration and facilitates consistent and reliable magazine feeding.

The manufacturer lists these features:

  • Solid copper (lead free), precision CNC machined design.
  • A unique nose that increases hydraulic velocity, creating high pressure spikes the manufacturer says result in a larger permanent wound column and more than twice the penetration of most expanding bullets.
  • A blunt nose for initial energy transfer and straight, deep penetration while allowing reliable magazine feeding.
  • Solid copper construction and cutting edges meant to punch through entry barriers without deformation or deflection.
