Does slop between barrel and action threads affect accuracy?

[QUOTE="birdiemc, post: 1788717, member: 29632"] I've been wondering this too. From a purely logical standpoint it seems the flat mating surfaces are what's providing the alignment. The threads would have to be pretty sloppy to cause any disturbance in the force. It seems the centerline of the bore and receiver would be coaxial/parallel as long as the mating surfaces are square. And I think the geometry of threads in general would prevent coaxial misalignment of the bore to the receiver. If there was .005 difference in the threads, would the barrel settle into the receiver threads while remaining square but misaligned? Or does the 60deg taper help to center the two? [/QUOTE]
