I was just watching some netflix and reloading and ran into a strange problem. The 9mm case I was trying to load kept locking up in my RCBS lockout die. I checked the powder and it was right on 3.4gr which is where it should be. I re-dropped the powder and it did the same thing. I rechecked my lockout die with a different normal case, empty case, and double charge and it was working perfectly. I rechecked the case and it had a fresh primer and was marked 9mm. Upon holding it up next to another case, I realized it was too short which was throwing off my lockout die.
Upon further inspection I realized it is actually marked 9mmBr.C. After some googling apparently Br.C. stands for Browning Corto or Court in Italian or French. It's apparently 380 although normally if I get a stray .380 round in my 9mm brass it usually jumps through my shellplate (Hornady Lock-N-Load) when I go to prime. It was all very strange. Now the bastard ate one of my primers and I don't shoot .380. Just wanted to post this in case anyone hadn't heard of this. It was a first for me.
