LeHigh Defense / Underwood .40 S&W 115 Grain XTREME DEFENDER UND-811

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:

• Flutes that force fluid inward to build hydraulic energy and expel it radially.
• Consistent penetration and wounding performance despite encountering barriers via monolithic material and non-expanding design.
• Lightweight – high energy, low recoil
• It does not rely on deformation for resistance in soft tissue, thus eliminating concerns of over-penetration resulting from a lack of expansion.
• Barrier Blind - minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers
• Lead-Free
• Streamlined manufacturing process over original CNC design.

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 metals.

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 brass.
