The only true way to know is by velocity. Chrono the loads and adjust accordingly. Load data is a GUIDE designed to get you close. It's impossible to replicate lab results in the field. Decide on a how fast you want them, study the data and build some loads. Then, shoot them from YOUR gun and check the velocity! YMMV
