Last week I finally obtained two boxes of CorBon .38 Sp DPX ammo. On the packaging the velocity is cited as 1200 fps, which is impressive. However, there is no +P designation. This I find curious as I have never seem +P ammunition not clearly labeled as such. What do I have? Thanks.

Corky, I'd go directly to Corbon & ask them. I'd think they're the ones who'd know the pressure level & whether it's safe in your gun. Just my 2 cents, JD45

Mr. Camp: Checking the CorBon Web site has produced more confusion. DPX38110/20 is listed on their ballistics chart as a +P load at 1200 fps. This is what I purchased w/ the exception that the +P designation is absent on the packaging, which is of the new design. And as your review points out, the older standard velocity DPX is also a 1200 fps load. What's going on here? --c

Hello. I'm not sure, but it was originally released as a standard pressure load and then later that one was no longer offered, being replaced with the +P designated one.

You might contact Mr. Mike Shovel at Corbon: [email protected] and I'll bet he will know the answers.

Best.

I have both the original and +p and only the recent box is marked +p. Look at the case head. If your load is +p it will be marked as such if it isnt then you have the original load. Nothing wrong with that at all. Both the +p and original load are in the newer packaging.

Thank you, xcop. I'm still wondering, however, why a standard load and a +P load are both cited as 1200 fps, and why the +P ammo (so marked on my cases) is not indicated as such on the box. Could be a problem if fired in my old, and I mean old, S & Ws. --c

I've got news for you anyway...neither one of those will do 1200fps from any standard length barrel. I have chrono'd the DPX 110+p out of a 3 inch sp101 and it did an average of 1056 fps. The regular CorBon 110+p did 1207fps from the same gun. I dont see my notes from the non +p right now but memory says it was just over 1000fps from a 2/18 barrel. The +p dpx is controllable and low flash and is travelling faster than other loads..except CorBon from a snub barrel. It is a good load and lower pressure than the Winchester +p+ you were asking about even though velocities are similar. 1056 vs 1076 from the 3in. The bullet is a better design.

The initial lot of 38 Spl DPX was designated as standard pressure and velocties were obtained using a 4" barreled Ruger GP100. The initial lot showed signs of not stabilizing the bullet, so we increased the velocity and pressure and that problem seems to be resolved. Our new test gun is a 4" S&W 686 and the velocity reads with it are 60 fps lower than the GP100. Hope this helps to clear up some of your questions here.
