Does anyone have any info [derived from actual shooting comparisons] of degradations in accuracy resulting from adding spiral flutes to a Rem 700 bolt in a modestly built custom .257 Roberts rifle? I didn't think it would affect it, but my smith [whose quite conservative about such things] has recommended against it for fear of introducing stresses into the bolt which might still affect accuracy even though the body resides aft of the locked up lugs. I know that PacNor does this as a service and it is performed by a few custom gunsmiths out there. But does anyone have any experience after making this enhancement to their firearm?
