Underwood Ammo produces this ammunition with the Lehigh Defense Xtreme Penetrator bullet. Precision CNC machined from solid brass, this bullet is good for the environment and really, really bad for the target. The unique nose creates high pressure hydraulic spikes that make a huge permanent wound channel while achieving twice the penetration of expanding bullets. The round is loaded with flash suppressed powder to preserve your night vision should you need to take a critical shot at night.
