[QUOTE="Mike 338, post: 1674332, member: 41338"] Didn't read the whole thread because of lots of pages so this is maybe a repeat. Just drop down about 5% below your max charge weight and load a single shot in .2 or .3 gr. increments all the way up to max charge weight. It'll be about 15 shots or so. Shoot them over a chronograph and record your readings. Chances are, two or three will be very close together. Load about 10 shots with a powder charge smack dab in the middle of where your test showed the best ES. Test for ES and accuracy. H-4350 and RL-16 are good powders in that caliber. Also, before I do any load workup, I do a rough seating test first. [/QUOTE]
