[QUOTE="Mikecr, post: 1002420, member: 1521"] There is no way to input all the factors accurately until determined with testing. This, with either QL or PT. We guess to begin. Also, there is nothing predictable about primer-powder ignition today. A change in flash hole makes a big difference, load density, temperature, primer seating/crush, pocket tightness, striker forces, brand to brand differences, lot differences. I agree fully with what Ridgerunner665 posted. Just consider how many ways a 'load manual' could be wrong, and then how advanced QL is w/resp to load manuals. We're very lucky to have as much.
