Description
Cor-Bon's DPX line represents purpose-engineered ammunition rather than a one-size-fits-all approach. This .300 AAC Blackout load uses a 200-grain solid copper projectile running subsonic at 1,060 feet per second, making it an excellent match for suppressed rifle systems. The subsonic velocity keeps the crack out of the round, allowing your suppressor to work at peak efficiency.
Deep Penetrating X Bullet Design
The DPX bullet is a homogenous solid copper hollow point that handles barriers the way defensive ammo should. Unlike traditional jacketed hollow points that can fragment or separate when hitting automotive glass or steel, the solid copper construction maintains 100% of bullet weight after penetrating barriers. This barrier-blind performance means you don't lose stopping power if your first shot has to go through car glass or a windshield. The hollow point is generous and designed to expand consistently in soft tissue while the base of the bullet stays intact for penetration depth.
Tactical and Hunting Performance
At subsonic velocities, this cartridge sits in a sweet spot between traditional handgun ballistics and full-powered rifle rounds. The .300 Blackout is known for performing well in short-barreled rifles, and this load takes advantage of that. It's particularly effective for hunting medium-sized game like whitetail deer and hogs within typical engagement distances. The 200-grain bullet doesn't require a suppressor to work, though suppressed setups make it even quieter. Whether you're running this suppressed or unsuppressed, the round cycles reliably in AR-pattern rifles with standard magazines.
Construction and Reliability
Each round is loaded in brass cases with Boxer primers, so if you're into reloading, the brass is reloadable. Cor-Bon uses quality control that's tighter than commodity ammunition, and this DPX load is no exception. The ammunition is lead-free, which works well in certain jurisdictions and reduces exposure concerns during extended shooting sessions. You get 20 rounds per box, with larger case quantities available for folks who shoot regularly.

Frequently Asked Questions
Does this DPX load work without a suppressor?
Yes, the 200-grain DPX cycles reliably in standard AR-15 rifles with or without a suppressor. The subsonic velocity is optimized for suppressed use, but it functions fine in unsuppressed platforms. You'll get more sound signature without a suppressor, but reliability and performance remain consistent.
What makes the solid copper bullet different from regular hollow points?
Solid copper bullets maintain their structural integrity better than traditional jacketed hollow points, especially when penetrating barriers like automotive glass or heavy clothing. Because the entire projectile is copper, there's no jacket separation or fragmentation. The DPX specifically achieves 100% weight retention even after barrier penetration, which means consistent stopping performance in real-world scenarios.
Is this suitable for hunting deer and hogs?
The DPX 200-grain load is designed for hunting medium-sized game including whitetail deer and hogs at close to moderate ranges. The heavy bullet and consistent expansion work well for ethical harvests. Performance drops off significantly beyond 150-200 yards due to subsonic velocity, so match this load to your typical hunting distances.
Can the brass cases be reloaded?
Yes, the ammunition uses Boxer primers and brass cases that are fully reloadable. This makes it a practical choice for shooters who reload, since the component cost per round can offset the premium price of factory DPX rounds on subsequent reloads.
