[QUOTE="IdahoCTD, post: 1782863, member: 13110"] With that method your assuming the bolt raceway is perpendicular to the chamber/bore and when your locking it down its not moving. That's not generally the case with factory guns. If you use a long stem indicator on just the muzzle end you know the bore is straight. Just because a barrel is turned between centers from the factory or from a aftermarket company doesn't mean the bore is centered anywhere else between those 2 points and the odds of it not being perfectly centered are way higher. Take a 27" blank and cut it to 24, 22, or 20" and see if its centered. How many factory actions have the threads and action face perfectly centered and square to the bore? Short answer is almost none. Add in a sandwiched recoil lug, like a Remington, that isn't parallel and your action is pointing a different direction from your barrel. I would love to see you make a split, bolt together, bushing and turn it true in your set up. Then remove the barrel and put it between centers. Measure the bushing and see if it runs true. My bet is it doesn't, especial if you measure it in multiple spots on the bushing. [/QUOTE]
