XD technology is based on Fluid Transfer Monolithic dynamic. The design goal was to achieve barrier performance and massive permanent wound cavity.
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 hollow-point comes close to achieving anywhere near this diameter of volume. Not only is the PWC over 100% larger than any other expanding bullet, it is near barrier blind, ignoring wallboard, sheet metal, and automotive glass
