I've done the same thing as the original poster ,but now I also am trying to watch the published pressure readings, if available,plus coal vs bullet weight to get load densities for the available space in the cartridge as kind of a double check to what max should be.That is what I'm assuming some of the variances come from. When bullets are seated deeper, AKA less volume for powder, the charge weight has to go down too. Is my thinking right?
