How do you measure to the ogive? Doesn't the ogive vary in diameter from the OD of the bullet to near zero? Unless your comparator measured from the same diameter point as the seating plug it seems you'd still be chasing bullet variance.

Or is there an accepted standard ogive diameter for each caliber?
