Frequently Asked Questions

Why does CorBon DPX use a solid copper bullet instead of a traditional jacketed hollow point?

Traditional jacketed hollow points rely on a lead core surrounded by a copper jacket, which can separate on impact or clog with barrier material — causing inconsistent expansion. The Barnes X bullet used in CorBon DPX is machined from a single piece of solid copper, so it never sheds weight regardless of what it passes through. Internal serration cuts replace traditional external grooves, allowing the nose to peel back into six uniform petals that nearly double the bullet's diameter while maintaining 100% weight retention for reliable deep penetration.

Will CorBon DPX 357 Magnum work in my revolver or lever-action carbine?

Yes. CorBon DPX 357 Magnum is loaded to standard 357 Magnum SAAMI specifications and functions reliably in any firearm chambered for 357 Magnum — including revolvers from Smith & Wesson, Ruger, and Colt, as well as lever-action carbines from Henry and Marlin. The all-copper bullet's smooth profile also feeds smoothly in semi-automatic pistols chambered in 357 SIG, though this load is specifically for 357 Magnum firearms only.

How does CorBon DPX perform compared to standard 357 Magnum self-defense loads?

CorBon DPX consistently outperforms conventional jacketed hollow points in barrier-blind scenarios. Standard JHP ammunition can fail to expand after passing through auto glass, heavy clothing, or sheet metal — common real-world threats. The DPX bullet's solid copper construction and internal serration design ensure reliable expansion and deep penetration (typically 12–16 inches in ballistic gelatin) regardless of intermediate barriers, making it one of the most trusted 357 Magnum defensive loads available today.
