Hello all, I am attempting to re chamber a post '64 Winchester model 70. I have a take off barrel to replace the rusted out old one. My question is in order to align the sight screw holes in the new barrel I need to cut the barrel shoulder back approximately .055-.060. This also means I have to cut the tenon back and push the chamber approximately that much further into the barrel. Is it safe to do that or am I getting to far into the tapered portion of the barrel? Will the chamber walls end up to thin? I hope this makes sense. I know I could just plug the holes and use optics but would rather not if possible. Thanks in advance for the replies.
