[QUOTE="Fiftydriver, post: 35912, member: 10"] JR, If you use a live piloted crown cutting tool there is no chance to get teh crown out of alignment with the axis of the bore as long as you use the correct bushing to fit the bore perfectly and use a floating reamer holder to drive teh crown cutter. If the cutter is sharp, there will be no burrs and with the use of the correct sized bushing, it does not matter if the bore is centered in the barrel, the cutter will center of the bore perfectly anyway. I have rarely found mild pitting in the grooves to effect accuracy over 25 shots or so. If the lands are pitted badly this can be a different case but since the rifle was shooting very well for a factory rifle, I feel the pits were a cosmetic flaw more then an accuracy flaw. Just my opinion, as you said, I am sure the boys at PGW's had a good reason to do what they did to the barrel. Its just hard to guess about it without all the information they had when they had the barrel in front of them. Good Shooting!!! Kirby Allen(50) [/QUOTE]
