Underwood Ammo produces personal defense ammunition that uses the Lehigh Defense Xtreme Penetrator bullet. This is a CNC-machined monolithic solid copper projectile with radial flutes designed to force hydraulic energy inward, resulting in a permanent wound cavity twice that of any expanding bullet. The optimized design of the bullet maximizes penetration up to 18". This defensive ammo is loaded with flash suppressed powder to help preserve night vision, and is designed for reduced recoil.
