Corbon Dpx 10mm 155gr Brns X 20/500

CorBon DPX 10mm 155-grain Bonded solid copper ammunition delivers barrier-blind performance engineered for defensive applications where reliability after penetrating intermediate barriers is non-negotiable. The DPX round maintains 100% weight retention after passing through auto glass, steel, and comparable obstacles—a critical distinction that separates this load from conventional hollow-point designs that may fragment or shed core material under barrier conditions.

The 155-grain DPX projectile is manufactured from homogeneous solid copper rather than lead-core construction, eliminating the core-jacket separation that undermines performance when rounds encounter vehicle glass or sheet metal. Internal serration geometry controls expansion without compromising structural integrity, a design principle CorBon refined through extensive ballistic testing. At 10mm velocity levels, this bullet weight and construction deliver consistent expansion paired with deep penetration—key metrics for defensive scenarios where barrier defeat is a realistic consideration.

This 20-round box format suits shooters who prioritize defensive load consistency for duty carry or serious sport applications where the 10mm cartridge is the chosen platform. Law enforcement agencies and armed professionals who have adopted 10mm chamberings typically rely on barrier-blind ammunition to ensure point-of-aim accuracy and stopping energy regardless of intermediate obstacles present at engagement distances. The CorBon DPX 10mm 155-grain load is purpose-built for that demand.

10mm ammunition represents a segment where velocity and powder charge are substantially higher than 9mm standards, making ammunition selection critical for reliable function and performance. CorBon's reputation in the defensive ammunition space rests on manufacturing ammunition that performs in real-world conditions, and the DPX line is the company's flagship offering for that purpose.
