[QUOTE="Country Bumpkin, post: 1374409, member: 92230"] Hello All, I'm not sure what's going on here and was hoping you could help. I traded my custom rifle and am waiting on a new one to be built . . . so in the meantime I bought a project gun just to see what happens. Attached groups are at 300 yds with my Ruger American Predator in 6.5 CM at 300 yards, not very much wind (maybe 3-5, I’m not practiced at estimating wind yet). Cold bore shot is always to the right of shots 2-4. I just noticed while posting this that my sighting group (low and to the right) did the exact same thing and I didn’t capture in my group measurement. Look to the right, off the cardboard and just nicking the plywood. Anybody else having horizontal cold bore displacements? I would have assumed that cold bore would typically vary vertically more than horizontally. You will see I measured one group twice (if I could eliminate the cold bore variation I’d have a 1/2 min Rifle). Explanations, Resolution, comments, flaming....? Thanks everyone. [/QUOTE]
