[QUOTE="Fitch, post: 376028, member: 19372"] I've used start pressure in a gross way to set up powder tables assuming the bullet was jammed into the lands but not to fine tune velocity results. I'd never messed with the Weighting Factor at all. I'll experiment with those to see how it works for me. I have played with powder models a bit to see if I could improve Lil'Gun in a Hornet but gave up on that. It was getting to be hard to maintain a baseline and I don't really need QuickLOAD for that powder in a Hornet anyway - just fill the case and push a bullet in after it isn't much of an exaggeration. 13.2g is almost level full in the brass. Thanks. These I knew about. I measure the H2O capacity of all the brass averaged over 5 cases. Different brands can be quite different. Remington and Federal are different enough in my 7-MAG that one requires 0.4g of powder than the other to get the same pressure and velocity in the model - a difference that proves out on the chronograph at the range as well. Roger that! Thanks. I'll play around with start pressure and weighting factor to see what I can learn. Fitch [/QUOTE]
