  • Case – Nickel Plated Brass
  • Use – Self Defense
  • Quantity - 20 rounds per box

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.

*Falling within FBI guidelines

This round offers:

  • A permanent wound cavity (PWC)that is 2 times greater than any expanding bullet
  • Reduced recoil.
  • CNC machined from solid copper to overcome barriers to penetration
  • Radial flutes that force the hydraulic energy inward to build pressure
  • Minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers
