[QUOTE="SSgt G Cody, post: 3081792, member: 113303"] [B]Personally, with a highly desirable bullet, on a new loading project, I start with the upper 25% of listed loads, on its lower end. After full-length sizing and loading to standard specs, I find best node by 3-shot groups, increasing 1 gn at a time until pressure max appears.
