Will do, but I'm struggling with why that would matter.. measuring the BTO would tell me if some bullets are longer or shorter than others, right? If my brass is in the piston and the bullet is being pressed down from the top, it shouldnt make much difference if one bullet is longer than another one - there would just be more or less of the rest of the bullet in the brass - right?
Not arguing that it wont help since you guys have obviously seen a difference, I just don't conceptually get why it would.
