[QUOTE="Greyfox, post: 1339306, member: 10291"] My 6.5x284 at 3000FPS and 6.5x47 at 2880FPS using Retumbo and H4350 respectively will register a 5-6FPS change in velocity per .1gr of powder variation of my loads. This velocity change at 1000 yards is approximately a .1-.2 MOA point of impact change. I control my charge weights to +/- .05grs. I like my overall ES to be under 12 FPS for hunting and Tactical/PRS competition. [/QUOTE]
