And that's the point - there's no need to reface the bolt. I suppose people think they are "blueprinting" the action by truing up one of the action parts. However, I see bolt faces trued all the time on actions which still have factory faces on the receiver. This means the receiver was never trued first, making truing the bolt face a wasted effort.

Don't get me wrong, I am all for blueprinting an action when building a rifle for exceptional accuracy. But if the process doesn't begin with bore-lining and truing the receiver, nothing you do to the bolt will make a difference.
