Cor-Bon DPX .357 Magnum 125 Grain Solid Copper

Superior Defensive Performance

Cor-Bon's DPX ammunition represents a significant advancement in handgun defensive ammunition design. The foundation of this superiority lies in its homogenous solid copper projectile—a departure from traditional lead-core bullets that fundamentally changes how the round performs in real-world conditions.

Barrier-Blind Technology

One of the most critical performance metrics for defensive ammunition is its ability to function reliably after penetrating intermediate barriers. Most ammunition loses effectiveness after passing through auto glass, steel, or similar obstacles. DPX ammunition maintains 100% of its weight after barrier penetration, ensuring consistent performance regardless of what stands between you and your target.

Engineered Expansion

The DPX bullet employs internal serration cuts rather than traditional external serrations. This design allows the solid copper projectile to expand reliably and predictably, creating a double-diameter wound cavity with six razor-sharp petals. This expansion mechanism works consistently across a wide range of velocities and barrier conditions.
