So What Caused This?
I found these in a sack of range brass my son brought to me a couple of months ago. I don't know what gun fired them or when or if it was even one of ours. The brass was a mixed bag of different brands and the only pieces that have been this way so far are Winchesters.
I don't ever look at 9mm brass for bulges, much less blowouts, but I'm going to inspect every piece in this bag and I may just toss the whole thing and not worry about it.
What could have caused this?
