[QUOTE="Darkker, post: 1078628, member: 81406"] Bore and Grove diameters, and the corresponding differences in the amount that the bullet obturates and how that effects accuracy and bullets; which is the root of your question. Otherwise, for a general answer, it doesn't matter. A 5r 308 barrel, vs my pull button rifled, vs my poly hammer forged barrels all have the same amount of "adjustment" in any ballistic calculator.
