I recently chronographed a box of the "new" Corbon .38 Spl. DPX (lot no. 20180101). I used an S&W Model 642, a 638, a 1975 Colt Agent and a "modern" Colt Police Positive Special. While the advertised velocity is 1050 fps from a 2" revolver, I got an average of 949 fps from the snubbies. Only two of the short barrel launched bullets broke 1000 fps of the 16 rounds fired. The extreme spread on the two S&Ws was 119 and 102 fps. The 4" Positive averaged a respectable 1105 fps. I found that reliable expansion occurred above 960 fps. I am waiting for an email back from customer service at Corbon. Any thoughts from the brain trust?

Thanks for the report! An average velocity from the snubbies that runs below the reliable expansion threshold of the bullet doesn't sound too encouraging. Even at the advertised velocity there's not a lot of margin for error. What was the test medium for the expansion?

Please keep us posted on the company's response. It may tell us a lot about the new management and their product line going forward.

The test medium was three plastic gallon milk jugs full of water in a row. I covered the front with two tee-shirts, an old layer of denim and a piece of sweat shirt. I call it a "hill-billy' clothing barrier. Around here, you don't get even two layers of denim in a row unless you shoot 'em through their "overhauls" pencil pocket. The bullet stopped in the third jug. It was 55 degrees F.

Wilco on the response from the "new" Corbon.

I should have know when Corbon added outlandish shipping costs to their "HERO" accounts for military and LE veterans that some negative things might be going on at the new company. Corbon emailed me on March 21 saying someone would contact me soon on my "velocity deficit" issue . After another prompt from me and a three week wait, the crickets are still chirping here in Tennessee. Quality control has definitely taken a "nose dive" from the old days. Will let you know if they do wake up and tell me they want to resolve my problem.

Until then, I am steering away from anything Corbon. Production Quality Control and Customer Service were the hallmarks of the old company. Apparently, no more.

I met Mike Shovel at the NRA 2018 Annual Meeting in Dallas last Saturday. He is the national sales manager under the new management. He said for me to contact him this week. He said he would look into my low velocity issue with the new 2018 lot of Corbon .38 Spl. 110 gr. DPX (+P). I am hopeful I will finally get an answer as to what's going on with the "slow" DPX.
