Shooting at a match today, one guy switched his glocks over for a minute and we noticed a very discolored case showed up in the brass pile. He fired a couple of others from that gun to confirm, and each case ejected from that specific gun showed very heavy carbon on only one side of the case.
He was shooting fiocchi 9mm ammo, and his other glock did not produce cases like that.
The theory was that the chamber was misshapen, but I'm not convinced that would cause it. In my mind, if there wasn't a good seal on the chamber, the entire case would have shown burn marks.
I'm just curious as to what this indicates. Any ideas?
