The new firing pin hoe was drilled at an off angle and he made up for it by welding on and undersized pin. The primers would flow back into the firing pin hole and the new firing pin broke off at around 50 rounds. He was out of business when I went back to complain.
I wish I could remember his name so I could ad mouth him on the net...
My plan is to braze up and redrill the firing pin hole one of these days when I'm feeling brave. I've bought all the drill bits I need to do the job.
