Some of you might remember the story I told about the guy in my squad at ROTC advanced camp who filled a 7.62 blank all the way up to the tip of the "bullet" extension with powder from other blanks. I saw the round with a twig in it and the guy said "I had to put that in to hold the powder." After he had told me this I did my best to try to talk him out of firing it but he pretty much dismissed my advice. Oh yeah the rifle had a BFA on it.
We were doing a night raid patrol and after we "attacked" the objective he came walking up holding the three main groups of the rifle and he had shrapnel wounds on his left forearm. The magazine was not found, the fiberglass stock was split. The lower third of the bolt had been blown out of the bottom of the receiver. The gun was totally frozen.
Just found the photo. Not perfect but it is what I have. I think I took it with a Minox 16mm.
He simply told the TACs that it blew up and he did not know why. Nobody ratted Mitch out but he sure took out a nice new M-14.
