Well, got out an fired just 20 rnds with my bolt AR. Trying new ammo. I bought a couple of cases of Federal GM .223 that uses Berger 73 gn otm which is advertised as 2800 fps at the muzzle. Left the scope with setting from handloads that were running the same. First 2 shots clean cold bore were dead center on my sight in target then creeped up slightly. Dropped the elevation 2 clicks and moved onto an MR-31 and shot a 100-9x. First two shots on the MR-31C were at 11 oclock. Left the scope setting alone because they were Xs and the rest were down near 6, go figure. One thing I noticed with this ammo is it produces tons of white smoke. Almost like shooting black powder. I like the 7 rnds through the one 1/4" hole at 6. Now if I could get over being exhausted it would be a lot more fun. Whatta Hobby!
