Lehigh Defense has the audacity to redefine terminal performancethrough innovating bullet manufacturing processes. Audacity has led us to introduce a unique and innovative product, the Xtreme Penetrator (XP)product line, for both handgun and rifles. The progressive nose geometry allows for deep, straight penetration while creating a permanent wound cavity diameter exceeding that of most expanding bullets. To top it off, the bullet is solid copper or brass, and is able to overcome barriers to penetration; environmentally friendly, target unfriendly, very unfriendly, downright obnoxiously unfriendly.
The magic happens with the nose design where the radial flutes force the hydraulic energy inward and then as the energy is restricted, it accelerates outward creating high pressure spikes damaging surrounding tissue. Kind of similar to sticking your thumb over a garden hose. You can see the radial pressure spikes in the gel pictures. Each crack showing in the gel represents a permanent wound. The permanent wound cavity of the XP is from two to four times greater than what a flat or ball nose bullet generates and often larger than traditional expanding bullets. So what you get is exceptional penetration coupled with a larger permanent wound cavity. Look at the data chart, no other bullet gives you this wound volume.
