The Xtreme Defender is based on the popular Xtreme Penetrator product line. The XD ammunition has an optimized nose flute total weight and velocity to achieve a penetration depth up to 18 inches* with a permanent wound cavity (PWC) that is just simply enormous; no other expanding hollowpoint comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100% larger than any other expanding bullet expansion is achieved despite being shot through barriers. The solid copper body ensures that wallboard sheet metal and automotive glass will have no effect on the Permanent Wound Channel.

Underwood Ammo™ combines our trademark power and precision with Lehigh Defense masterfully designed Xtreme Penetrator bullets – the result is one jaw dropping round. This round is solid copper and features a unique nose that maximizes penetration and facilitates consistent and reliable magazine feeding. This round offers: Solid Copper (Lead Free) precision CNC machined design. Good for the environment bad really bad for the target Unique nose that increases the hydraulic velocity creating high pressure spikes resulting in a larger permanent wound column and over twice the penetration than most expanding bullets. Blunt nose for initial energy transfer and straight deep penetration while allowing for reliable magazine feeding. Solid copper construction and cutting edges to punch through entry barriers without deformation or deflection.
