With rough barrels, you do what you have to do, there is no getting around it. I have a Savage 116 in 7 Mag with beautiful wood. The barrel would shoot 1/4" and less for 9 shots, then went to 1.5". The barrel on this rifle looked like an old washboard road.
I can help you with your situation but would rather do this though PM's.
