I picked up a new redhawk rifle here are the specks . Remington 700 308 20" barrel 1 in 12 twist . Timney trigger set to 2lbs HS Presision stock . Load 178 Amaxs Winchester brass neck sized .002 neck tension Federal match primer RL 15 42.8 grains Ran them thru my chrono 2515 I had deviations from 9 to 11 FPS Here are my 100 yard groups this is a 4 shoot group at 100 yards I only loaded 4 for some reason don't ask why ? Went out to 400 yards and groups where still good under MOA . Doped to 600 yards could not hit the target ? I did notice that the last 15 loads I loaded and shot had .007 runout on them could this be my problem ? This baffles me ? I know that 180 grainer are about max for a 1 in 12 .
