The Lehigh Defense 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.
The XD ammunition has an optimized nose flute total weight and velocity to achieve a penetration depth range of 18 inches with a permanent wound cavity (PWC) that is just simply enormous; no other expanding hollowpoint comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100 percent larger than any other expanding bullet it is near barrier blind ignoring wallboard sheet metal and automotive glass.
Lehigh Defense was able to accomplish this quantum leap in terminal performance at the same time while reducing recoil. The terminal performance achieved is quickly approaching that of 5.56 rifle performance and that is an incredible feat.
