I am planing to replace the Barrel on my .308 to a better quality one. the action was already blue printed/lugs were done and just about anything I can think of. QUESTION?...If I switch my Barrel is there any other work that must be done to the action? I can keep all work @ tolerances of of better than NASA close. We have a Machine shop/tool and die, with grinders and Machines that would make any one go WOW!
