I would be glad to help you out but to be honest with you I am not a bolt gun guy to that degree. There are folks whose entire Smithing business is dedicated to precision rifles. They are worth every penny.
Westwind Rifles in Erie comes to mind. Long turnaround but nationally renowned work. I have seen some of his work and it is first rate.
Caleb Rutledge in Thornton is another one. I have not seen his work but I have heard good things of him.
Bighorn is first rate.
