Barrier-Blind Performance You Can Depend On – 357 MAG 125gr DPX
In self-defense, there’s no room for guesswork. You need a round that performs every time—no matter what’s in the way. COR®BON’s 357 MAG 125gr DPX is built exactly for that purpose. It delivers rapid expansion, deep penetration, and full weight retention through common barriers such as glass and steel.
Engineered for Reliable Expansion
This load uses our proven DPX® bullet, machined from a 100% solid copper slug. Unlike traditional hollow points that depend only on speed, the DPX is designed for controlled, mechanical expansion. Six sharp petals open on impact, nearly doubling the bullet’s diameter. As a result, you get a wide and permanent wound channel. The internal serration cuts also help ensure expansion stays consistent through clothing and other materials.
Tested Results You Can Trust – 357 MAG DPX Performance
During FBI protocol testing, this round reached 12–18 inches of penetration in soft tissue after passing through four layers of denim. In ballistic gel tests, recovered bullets kept 100% of their original weight and shape. This means no fragmentation, no surprises—just steady performance shot after shot.
Powerful, Lead-Free, and California Compliant
At 1300 feet per second and 469 foot-pounds of energy from a 4-inch test barrel, this DPX load packs serious stopping power in both revolvers and lever-action rifles. It’s also lead-free and fully California compliant, making it a smart option for carry or training in restricted areas.
Whether you’re defending your home or carrying concealed, this round offers dependable, real-world performance. When your life depends on it, trust the round that helped redefine modern defensive ammunition.
