[QUOTE="Hydra6, post: 2782828, member: 125161"] I do not claim to be a reloading expert by any means. Hornady has a great podcast (#50, #54?) that discusses how they develop loads. PRS Tactical Class dictates for 223 max bullet weight and max velocity. TAC meters like flour in a Dillon press powder drop. There is a world of online load data for 223, etc. (use caution but you can tell the knowledgeable pretty quick). That led pretty quick to a 75ELDM over TAC powder in a 223 case. I loaded 75 ELDM over TAC from 24 to 25 grains to find a load that was close to 3000 fps. Once I got close to my velocity goal I tried in .2 increments until I got acceptable load. I do not adjust seating depths (heretic) - just needs to meet mag length and fit into the chamber. Note - there are gas gun loads vs bolt rifle loads (higher pressure) plus 556 vs 223 loads (556 higher pressure). I approach 65CM, 6Dasher, and 6BRA the same way. [/QUOTE]
