[QUOTE="Pdvdh, post: 190927, member: 4191"] I believe they are talking about the rifling land versus groove diameters of the bore. For example, the groove diameter of a 300 Win Magnum is the same as the bullet diameter (.308 inches). However the rifling lands in the bore are at a diameter of .300 inches. So no, the bullets aren't swaged down by 0.008 inches in diameter, but the rifling does imprint into the jacket of the bullets. Make sense? [/QUOTE]
