Fracturing ammunition, like the new home defense and hunting rounds produced here at Engel Ballistic Research, are designed to fracture into several pieces after the projectile impacts soft target. The base of the projectile acts like a normal bullet and penetrates through soft targets by creating a single wound cavity, just like when a traditional round hits the target. However, fracturing ammunition is designed with other fragments, known as petals, that break away from the base creating separate wound channels in order to increase the lethality.
In hunting scenarios, the fragmentation that takes place results in a devastating transfer of energy and multiple large cavities around the multiple fragments. This results in an increase in bleeding and a high probability of a fatal shot, by creating a target zone around the vitals that is larger than with normal projectiles. This makes it popular with hunters who want to ensure that they make clean, relatively painless, and humane harvest of game, especially those that don't trust themselves to fire a perfect shot every time.
