Oh, the horror! The horror!
After four decades and countless thousands of CCI rounds fired, it finally happened. I got a dud. A true dud, since the gun has a firing pin strike like the hammer of Thor.
I'm torn between mounting it in a shadow box on the wall, or disassembling it to see whether it has no primer compound at all, or just has a gap in it.
I think I'll mount it. After all, it's so rare that it may have collector value.
