At a recent gun show, a friend and I were looking at clear plastic zip lock bags of fired brass in various calibers.
I was checking out a bag of 7.62x51 LC brass when a guy behind me said, "don't buy that brass. it's been fired from machine guns."
He was gone before I had a chance to ask how he knew.
Can anyone tell me how brass fired from a full-auto weapon appears and the differences compared to single-shot brass fired from, say, a bolt gun or semi-auto M1-A rifle?
