Cor-Bon DPX .44 Magnum ammunition (brand part no. DPX44M225) loads a 225-grain Barnes XPB solid copper bullet for hunters and defenders who need performance after punching through a barrier. DPX stands for Deep Penetrating X-Bullet, and Cor-Bon builds it as a homogenous copper projectile rather than a traditional lead-core design. Internal serration cuts, instead of external ones, let the bullet expand to double its original diameter into six sharp petals while holding onto essentially all of its starting weight. Whether the barrier is auto glass, sheet steel, or heavy clothing, this .44 Magnum load is engineered to keep working on the other side of it.

Frequently Asked Questions

What does barrier-blind mean? It means the bullet keeps its shape and performance after punching through obstacles like auto glass or sheet steel, instead of breaking apart.

Why does Cor-Bon use internal serration cuts? Internal cuts let the copper bullet expand fully into six petals without the weight loss that external serrations can cause.

Is the DPX bullet made of lead? No, it is a homogenous solid copper design, so there is no lead core to separate from the jacket.
