Lehigh Defense pioneered Controlled Fracturing Technology, designing bullets for unparalleled terminal performance. Made from solid copper and pre stressed at key points, these bullets deploy razor-sharp petals after reaching a predetermined penetration depth, releasing an energy spike before separating and radiating outward from the primary path. The bullet shank, now reduced to bore diameter, continues penetrating straight and deep along the original impact path. Unlike traditional expanding bullets that mushroom and limit penetration, Lehigh Defense's Controlled Fracturing ammunition delivers initial energy transfer, multiple wound paths and a deep penetrating base with a sharp cutting-edge for extreme terminal impact.
