This round exploded and blew the magazine up and I caught shrapnel in the face and hand...thank god it wasnt a glock! This is a sig factory mag.
That is almost certain a double charge. I had exactly the same thing happen several years ago with pretty much the same results. Peppered my face with a blast of high pressure gas and shrapnel. It actually felt like something hard hit me in the face, at first I thought the slide had broken.
Trashed the magazine, bulged out the pachmeyer grips, and blew the spring plunger tube off the side of the gun (never did find that little bugger). Good news is the gun was fine. No damage at all to the barrel (Kudos to Nowlin barrels). Had a new punger tube installed, and straightened out the grips, and it was good to go.
Bad part is, it happened at a match with EVERYBODY watching... and it was my handload...
