[QUOTE="climb-101, post: 1068657, member: 31921"] the comparator size is just for giving you a place to measure that is close to a given bullet diamiter and let you measure that same diamiter on all the bullets on that given size. the bullets can be different shapes though and that will move that given diamiter up or down on a bullet. here is a picture of 2 different bullets "A" and "B". the lines represent where the ogive is and also where a comparator would hit the bullet. if you had your press/die set up for bullet "A" to have a .010" jump to the barrel and switched to bullet "B" it would still have a ".010" jump but it would have a longer OAL because the ogive is further down the bullet because of the shape. if you measure just the bullets from the ogive to the base they will also be different even though they are the same length from base to tip.
