Ok guys got a barrel boring rifling machine and working up to do a 50-110 Winchester barrel. Got just about everything to get the job done. I'm going to do cut rifling and have my first cutter body done and will probably do one or two more before I do my barrel. I'm wondering about cutter dimensions....anyone done a 50 before and willing to share info or can anyone point me in the right direction for dimensions on it and other calibers?
