CorBon DPX 10MM 155 Grain Barnes X Bullet - 20 Round Box

CorBon DPX 10MM ammunition is a solid copper defensive load built for shooters who demand reliable, consistent performance when it matters most. Each 20-round box contains 155-grain Barnes X bullets—the all-copper design that sets CorBon apart in the defensive ammo market. Whether you're running a 10MM pistol for personal defense or field carry, DPX rounds are engineered to deliver deep, predictable penetration paired with controlled expansion, even after passing through intermediate barriers.

What makes DPX distinctive is the construction: a homogenous solid copper projectile with internal serration cuts rather than external notches. This design lets the bullet expand fully on impact, creating a larger wound channel while maintaining its weight through barriers like auto glass or steel—a characteristic CorBon calls "barrier blind." The result is ammunition that doesn't shed velocity or energy when it has to work in the real world.

CorBon has built a reputation among serious shooters for ammunition that performs when other rounds fall short. The 10MM cartridge is no casual choice—it demands the same commitment to quality that a shooter brings to their platform. DPX pairs that power with bullet construction you can trust, whether you're training at the range or carrying for protection.
