Winchester Ammo Incident

If you scroll through the thread they show a picture of the brass case. If you go to near the end, the HK reply to the guy is "our firearm was not the issue" while Winchester tells him they will be sending him a new pistol and complementary ammo, suggesting that Winchester's round was the issue.

It was first, a 40 cal S&W, a cartridge known to operate at high chamber pressures. It blew out at the feed ramp and extractor cut, the unsupported portion of the barrel/chamber. High pressure? Maybe. Another possibility is a poorly formed and drawn case, with a defective web. I don't buy into the "double charge" theory. A double, in my experience, would have caused more damage at the chamber. This blew the case, and vented into the magazine well, cracking the plastic frame, and popping some other parts loose. I think it was a bad piece of brass.
