Re: FP Bushing Question
The more I think about it, the more I come to the conclusion that the action should be trued first. My thinking likewise has to do with squareing the boltface. If in fact the boltface requires machining, the FP hole could theoretically be "oblonged" in the process--assuming the FP hole was orginally drilled perfectly perpendicular to the "unsquare" boltface.
By bushing after truing, when the new hole is drilled in the now bushed bolt, everything hould come out square.
Probably overthinking this one...
