I bought a lot of brass that was supposed to be once fire and it turned out to be a lot of junk, but that is another story. I found some interesting cases in there. Take a look.
The blown one is a 9mm, almost certainly fired out of a 40 S&W. The others are 45 acp with bulges that match 1911 type barrel cuts.
