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
Nickel plated casings with our new nickel plating process provides
several key benefits, not limited to but including; improved feeding in
all actions of firearms, enhanced corrosion resistance over traditional
brass, improved cosmetics, and ease of cleanup during reloading. Nickel
plated casings will not tarnish like brass during storage or when in
contact with foreign materials such as leather, moisture, and other
Until the development of the Ducta-Bright 7a process, nickel plating
casings often limited the number of reloads as compared to raw brass. It
was claimed that nickel plated brass casings embrittled the brass
therefor making it less desirable for reloaders despite the ease of
cleanup that nickel plating offers. In addition, ammunition engineers
raising concerns of using nickel plating in very hot +P or magnum loads
found that traditional nickel plating often cracked deep-drawn cases, or
worse, lead to a total failure. This new process eliminates any
concern, to the shooter or reloader, of hazard or ability to re-use the
