Lehigh Defense Xtreme Defense Ammunition features the proven Xtreme Defense bullets. This high quality ammunition is perfect for hunting or pest control. The lead free projectiles are safe to use in any environment with no risk of lead contamination. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases. The Xtreme Defense (XD) Technology is based on the popular Xtreme Penetrator product line. The design goal was to achieve the same barrier performance and massive permanent wound cavity and reduce the penetration depth to coincide with an individual's personal comfort level. It was a goal Lehigh did not meet; it was a goal they blew out of the water!
