[QUOTE="Bart B, post: 686860, member: 5302"] Yes, truing up the receiver face square with the barrel tenon threads in it will true the action enough. Be sure the receiver's face will be square with the barrel tenon threads, not the boltway axis; that boltway's not always aligned with the barrel tenon threads. There's not enough stress from an 8-pound long barrel hanging off that receiver to get concerned about. When that .300 RUM barrel whips as its fired, the stress on the receiver where the barrel shoulder fits hard against it will be a lot more than what the weight of the barrel alone puts on it. Its muzzle will whip through a much greater vertical arc either side of zero when fired that what the barrel normally droops below zero at rest from its own weight. After the receiver's faced off, that's a good time to thread in a collet with a stopped end mill in it whose cutters are at the diameter of the bolt face. Using that setup will get your bolt face square with the barrel tenon axis and your fired case heads will be square. Otherwise, you'll end up with out of square case heads and that's a detriment to good accuracy. [/QUOTE]
