Hello...I picked up my first big rifle recently. I've notice that when i chamber a round into the gun that the feed ramp seems to scratch the cases a bit.. I have put 40 rounds through it and was thinking perhaps i should have the ramp polished. I have searched and search and found no information on this. I am worried about the cases being scratch because i intend on hand loading and I'd prefer the cases not be marked! The Model of the gun is a Remington 700 sps .308 . I appreciate any and all advice. -Joey
