CorBon DPX 357MAG 125 Grain Barnes X Bullet - 20 Round Box

CorBon DPX 357 Magnum ammunition delivers proven stopping power for defensive handgun use. Built around a homogeneous solid copper projectile engineered for barrier-blind performance, the DPX is purpose-built to perform when it matters most. Whether your .357 Magnum serves as a defensive sidearm or backup weapon, this 125-grain load prioritizes terminal reliability through obstacles and structural barriers you hope never to encounter—but can't ignore in a defensive scenario.

The DPX's design centers on a 100% solid copper bullet with internal serration geometry rather than external cuts. This architecture enables controlled, full-diameter expansion with six distinct cutting petals on impact. CorBon claims the bullet maintains its full weight through intermediate barriers like auto glass and steel, addressing a critical gap in defensive ammunition performance that traditional jacketed rounds often fail to handle.

Each box contains 20 rounds, sized for shooters who want to practice with their carry load and defenders who stock reliable duty ammunition. The 357 Magnum platform offers proven stopping power in a compact, controllable package—ideal for both snub-nose revolvers and mid-frame handguns used for personal protection.

Frequently Asked Questions

Will CorBon DPX ammunition work in any .357 Magnum revolver or semi-auto?

Yes. The 125-grain DPX load is standard .357 Magnum ammunition and will function in any firearm chambered for .357 Magnum, including revolvers and semi-automatic pistols designed for the cartridge.

What does "barrier blind" mean, and why does it matter?

Barrier-blind performance refers to the ammunition's ability to maintain stopping effectiveness after passing through intermediate barriers like auto glass, steel, or heavy clothing. CorBon states the DPX maintains 100% of its bullet weight through such barriers, preserving the projectile's integrity and terminal performance when defensive encounters occur in real-world environments rather than ballistic gelatin.

Is CorBon DPX ammunition suitable for target practice or only defensive use?

While DPX is engineered as a defensive round, shooters often practice with their defensive load to ensure familiarity and reliability. A 20-round box supports both training and duty carry, though cost considerations may lead some to practice with standard ammunition and reserve DPX for carry.

What is the difference between CorBon DPX and traditional jacketed hollow-point ammunition?

The DPX uses a solid copper construction with internal serrations instead of a lead core with external hollow-points. CorBon emphasizes that this design maintains full weight through barriers and delivers controlled expansion with six cutting petals, contrasting with traditional jacketed rounds that may shed weight or fail to expand predictably when encountering intermediate barriers.
