[QUOTE="Edd, post: 1369235, member: 30592"] The print shows 2.045" from base to front of neck. The print shows the step from the neck diameter to the freebore diameter goes from .319" to .2845". That is .0345". If the angle is 45°, most of them are, that will add .01725" to the length. The print shows .180" freebore. The print shows a 1.5° throat angle. To get from the .2845" freebore diameter to a .284" diameter at a 1.5° angle adds .00955" of length. 2.045" + .01725" + .180" + .00955" = 2.2518" I'm guessing you are measuring your bullet at some diameter less than .284". The distance from the front of the bearing surface to the point where your measuring tool contacts the bullet will be determined by the shape of the bullet. So your measurements won't be the same with all bullets. [/QUOTE]
