Ill try to keep it short.
My model 700 remington 300 ultra mag got somewhat rusty before deer season. I decided I wanted it parkerized but opted to shoot a few deer with it first. Then I took it apart and cleaned the rust out and got ready to ship it. Unfortunately, I changed my mind and want to use it for the rest of the season.
Here is the problem. When I put the rifle back together. The cartridge seemed to big for the chamber. It is like the chamber shrunk in size or something. It would not even fit all the way unless I used exessive force. Anyway, I sand blasted inside the chamber and now the case fits again. Do you think my rifle is safe to shoot?
