I've seen a few clear gel tests on the new version of Corbon's DPX in 9mm. The new bullet has cuts for thicker loner petals. The bullets in the tests expanded to about .85 and penetrated to around 13 inches. This seems clearly to be something new on the market to at least consider.

It would be interesting to see a test with autoglass and also a comparison against HST.

What do you guys think? Have any of you tested this round?

I have tested DPX in 9mm, .357SIG, and .45 out of a short barrel and their results were outstanding. However those tests were with the original DPX. I went on Corbon's site and I don't see where you can purchase "new" DPX?  I tested Corbon's DPX not Barnes loads

They've moved to the new version on their website, at least in 9mm I would ask about other calibers. The 9mm will be the version that opens to .85.

Yeah I'm interested in how the new design does.

How did the dpx you tested do penetration-wise? Just 12-14in? Those who have tested it say it opens up more reliably than about anything.

The DPX rounds were all very consistent through 1)bare gel, 2)Winter wear consisting of Medium weight nylon outer shell filled with thinsulate. Cotton hoodie and 5.3oz cotton Tshirt. 3)4 layers of heavy denim and 4) one layer of 5.3oz cotton t shirt
All the 9mm, .357Sig, and .45 DPX expanded through all four of these media into a 10% clear ballistics gelatin

IN .45 Shield short barrel Corbon DPX 185+p is the most consistent with penetration to 13-14 1/2". Expansion .819.
Golden saber 185+p penetrated to 16-17" expansion .740".

In .357 Sig Corbon DPX 125gr penetrated to 17" and expanded to .680"
