[QUOTE="Pudgy, post: 2747250, member: 124264"] I usually dont respond to these types of questions as there tend to be lots of conflicting answers, however, i have test over 1,000 rounds in the last 4 months. There is more to the subject then I can write here, so here briefly is my observation. Low ES/SD is about consistent ignition Percentage of case fill doesn’t impact ignition. Doesn’t impact es-Sd Use high end brass eliminates a lot of issues. Sorting brass and primers has little to no impact on ES/SD Anneal-trim every time, (while I mandrel, have not noted impact ES/SD Bullet of consistent weight & bearing surface Measure powder to .02 (V4 or SuoerTrickler make this easy) Find right powder - primer combo. For PRC changing from fed 215 to 210 primer SD when from 26 to 4 over 10 shot strings with PRC find a node at least .4 grains wide with little velocity change. Hope this helps and doesn’t add to the confusion. [/QUOTE]
