Lehigh Defense pioneered Controlled Fracturing Technology, designing bullets for maximum terminal performance. Crafted from solid copper and pre stressed at specific points, these bullets deploy razor-sharp petals after a predetermined depth of penetration, releasing an energy spike before separating and radiating outward from the primary bullet path. Meanwhile, the bullet shank, reduced back to bore diameter, continues to penetrate deeply and straight along the original impact route. Unlike traditional expanding bullets that mushroom and limit penetration, Lehigh Defense's Controlled Fracturing ammunition creates multiple wound paths, intense energy transfer and deep penetration, with a sharp cutting-edge for extreme terminal performance.
