I am recommending that you use extreme caution if you are reloading any 40 cal. PMC cases. The cases that I had were of two part case construction and the base had been expanded into the side wall portion. I recently had two cases come apart when fired in my S&W Mod. 4006 pistol. I was firing a batch of 100 mixed brand cases that had been once fired and reloaded with a conservative load of 4.7 gr of Red Dot behind a 180 gr LSWC.
The two PMC cases blew apart upon firing, sending a tremendous blast down and out of the trigger area and along side the clip. Both case walls remained in the chamber and both case bases were found directly below the gun, at my feet.
I have since sorted out more than 3000 rounds of cases and thrown out every one of the PMC's. I have dissected several once fired PMC's in 40 cal and 45 auto to take a closer look. The seam joint is very obvious in the 40's, but the 45 ACP's were found to be made by standard one-piece construction.
I would recommend that you check any 40 cal PMC's in your supply and take the appropriate steps. In 45 years or more of reloading, I have never seen this type of case or experienced such a separation and scare.
