Please, a number or the like to characterize "overbore" would be handy.
While I would say that it is relative to what the individual building the rifle is comfortable with, I'd say that it'd be best characterized as a ratio of powder weight to velocity, or, to make it a comparison, how much powder weight one adds to get a certain increase in velocity.
Would you all agree that'd be fair, recognizing that everybody would have their own definition from build to build?
