Lehigh Defense Xtreme Defense .429 160gr Lead-Free

Lehigh Defense Xtreme Defense Ammunition

The Lehigh Defense Xtreme Defense (XD) represents a fundamental shift in how modern self-defense ammunition performs. Built on proven Xtreme Penetrator technology, these bullets combine barrier performance with devastating terminal effects.

Design and Construction

Solid Copper Monolithic Build

• Lead-free construction for environmental responsibility
• Single-piece copper design eliminates separation issues
• Progressive nose geometry engineered for controlled penetration

Terminal Performance

The Xtreme Defense achieves what few expanding bullets can match:

• Permanent wound cavity exceeding 100 percent larger than conventional hollow points
• Controlled penetration optimized for 18-inch depth in ballistic gelatin
• Barrier-blind performance that defeats drywall, heavy clothing, sheet metal, and automotive glass without deflection or expansion failure
• Deep, straight penetration that creates a massive permanent wound cavity while maintaining structural integrity

Practical Advantages

Unlike conventional hollow points that lose effectiveness when passing through barriers, the Xtreme Defense maintains its terminal characteristics regardless of intermediate obstacles. This barrier-blind capability means your defensive load performs consistently whether the threat is behind clothing, vehicle glass, or structural material.

The ammunition also delivers reduced recoil compared to conventional magnum loads, making follow-up shots more manageable while achieving terminal performance approaching rifle-level effectiveness.
