Corbon DPX ammunition in .300 AAC Blackout brings serious stopping power to a platform prized for its versatility. This 200-grain subsonic load pairs the caliber's inherent subsonic velocity advantage with solid copper hollow-point construction designed to deliver controlled expansion and deep penetration—whether you're running a suppressed SBR for home defense, training on a private range, or working in hearing-protection-required environments. The DPX line is engineered around barrier-blind performance, meaning it maintains terminal effectiveness after passing through common obstacles like vehicle glass or steel, so your shot placement matters more than your backstop.

The 200-grain subsonic load is a sweet spot for .300 Blackout shooters wanting reliable performance at close to moderate ranges without the supersonic crack that announces itself downrange. Corbon's homogenous solid copper projectiles are built to stay together through barriers and tissue, avoiding the fragmentation or weight loss that compromises some other defensive rounds. That's critical in any scenario where over-penetration or deflection could be a concern.

This product ships as a 20-round box in a 500-round case, making it suitable for stocking a defensive rifle or working up loads for a new platform. If you're building a quiet, effective .300 Blackout rifle for defense or tactical training, the DPX subsonic load deserves a spot in your selection process.

Frequently Asked Questions

Is this .300 Blackout ammunition subsonic?

Yes. The 200-grain DPX load is loaded to subsonic velocity, which makes it well-suited for use with suppressors and keeps the report signature lower downrange.

What does "barrier blind" mean on this ammunition?

Barrier blind refers to ammunition that performs consistently even after passing through heavy barriers like vehicle glass or steel. The solid copper construction of the DPX allows it to maintain its weight and terminal effectiveness after penetrating these obstacles, rather than fragmenting or losing performance.

What are the solid copper bullets designed to do?

Corbon's homogenous solid copper projectiles are engineered to expand in a controlled manner and penetrate consistently through tissue and barriers. Unlike some ammunition that fragments or sheds weight when hitting barriers, the DPX maintains structural integrity for reliable terminal performance in defensive scenarios.

How is this ammunition packaged?

This product is sold as 20-round boxes packed into a 500-round case (25 boxes total), giving you flexibility to stock and use the ammunition as your needs require.
