[QUOTE="jeff 300, post: 171893, member: 4145"] what is a good spread on your speed? mine is jumping all over the place. I'm shooting a kirbybuilt 338edge with retumbo and h1000 with 300gr smk's. both powders are doing it. the h1000 is not as bad but still. am planning on running just the h1000 and got a 8# can the other day. could this be a bad chronograph. i have the shooting chronoy F1. i know it's not the best but thats what i have. all of the groups where shot in good sun light about 10 feet in front of the barrel. a 3 shot group 92 gr of h1000 2856,2819,2834 92 gr retumbo 5 shot group 2846,2847,2860,2809,2821 93gr retumbo 7 shot group 2884,2828,2836,2867,2857,2854,2876 is this as bad as i think are am i just over doing it? i see some guys get only a 10 fps change but all of mine way over that?
