Any one tried the twist rate change through quickload? I have in the past and I am pretty sure it predicted negligible if any pressure differences. I am in ND today and do not have Ql on this computer. I have shot hot loaded 55gr loads set up for my 14T 223 through my 7T 223 with out a problem.
STOP IT. Real world experience is not welcome here. It ain't near as humorous either....grin
