[QUOTE="Dragoon300, post: 2031918, member: 115285"] I just fired 10 rounds I loaded yesterday. 6.5 PRC w/ 156 gr. Bergers and 64.0 gr. N570 COAL ref. 3.082" .010" off lands CBTO 2.400" 31" Bartlien 5R 1: 8.35 - 1: 7.35 gain twist. Average 3269 fps on Magnetospeed chassis mounted. 2 minute intervals. 50 degrees F, SD 7.4 fps, ES 21 fps. 7/8" moa. This is the first group I have fired in this barrel, anyone have any suggestions for improving my group? I shoot prone with bipod and rear bag. This is a Desert Tech SRS that I have been shooting in 338 Lapua for the last 5 years and have shot better groups than this. I am attaching a photo with data on it.[ATTACH type="full"]228192[/ATTACH] [/QUOTE]
