The listed dimension is where the throat ends and bore diameter starts.
More significant is the point where the throat gets tighter than the OD so standard bullets. That would be the start of the throat. The shoulder of the bullet won't go further forward than about this point without engraving lands onto the bullet.
So I am assuming that you are referring to the point that the lands start at .256" diameter?
