I have a model 70 Win. in 7mm Rem. Mag. I think this gun has excessive head space. I start getting case head seperation after 3 or 4 loadings. That is after full length resizing. This gun shoots real good. I just want to see what my options are. Can this gun be reamed to a 7mm STW? If so will the bolt and magizine work for the STW cases and bullets? I have another 7mm Rem, and I have dies and a lot of brass for the STW and no rifle at this time. The STW I had would not shoot accurate and it moved to a new home.
I know I could have the barrel cut, rethreaded and set back, or necksize to increase the number of loadings bofore wearing out the brass. What are my other options? What would you do if this was your gun?
