Here's the scoop.....Two 75's , been shooting them for about six months. No dry firing. very slight burr cropping up around the firing pin hole in the frame. Found this when the gun bound up in a shoot after three rounds. There is slight scraping on the cartridge base and across the primer. Took a stone to the face of the frame around the pin hole and this cured the problem.
However, its starting again.
Is this common to Remmies and is there a cure?
