[QUOTE="Blackhawk, post: 1796151, member: 105459"] When anything is machined there always will be manufacturing allowable tolerances.For the sake of argument lets say that your your barrels lug is not exactly square but has a little taper in it. Now carrying that one step further lets say that your stock to barrel fit, or your stock to action fit is poor and is either too loose or slightly rubbing up on the receivers bottom or sides.Or that the barrel lugs fit in regards to your stock is slightly binding. Or perhaps your action screws are not tight enough.Or the barrel nut to barrel fit is not tight enough or not true and square with the receiver.How about the barrels chamber face and walls . Are they true and square with your action? What i'm trying to say is what you may have is a combination of stacked tolerances that even though each individual part is within factory tolerances do to a combined tolerance stacking any one of which to lead to accuracy problems. In my opinion you have to examine everything. Only then can you take steps toward correction of these issues. Now I have not even touched on the head spacing issues that a barrel removal will cause. Unless a quality set of go -no go caliber specific chamber gages are used your rifle will never be correct. I myself would find another gun smith and have him examine and subsequently repair your rifle. Personally I would be leary of a smith that did not promptly return your phone call.as his/her reputation is now in question. I speak as a retired tool and die maker with over 45 years experience.
