Ok heres a difficult situation to pose........ I have a remington 700 5R, the bolt is tight on opening, even after dry firing. It seems as though something is rough in the bolt/firing pin area. I oil it and it smooths for a few cycles then grows tighter. Any ideas? I have had the bolt apart numerous times and lubricated it. Still goes back to tight after a few cycles. Any help would be appreciated. Its probably something silly that a rookie like me is missing, but I know there are more than a few experienced shooters that can lend some insight. Any help would be appreciated.
