Tested some ammo today to get an idea what this rifle likes, 6.5 Creedmor Bergara Premier in a Grayboe Ridgeback stock, only the second time I have shot this rifle. Bought it primarily to try my hand at some long range, with
the intention to start loading for it, I have never loaded as of right now. Shot 3 types of ammo today at 100 yds, Hornady 140gr ELD Match, Barnes Precision Match 140gr OTM BT, and Copper Creek Cartridge loaded with 142gr Sierra Match King. I was surprised at the disparity in the results. I shot the Hornady first, and thought it was decent, the Barnes next, my barrel/chamber did not seem to like it, not a knock on Barnes at all, and was wowed by the performance of the Copper Creek. First 3 shot group was the upper left in the photo, adjusted the scope, and shot the center group. I figured their MOA at .233 and .317, respectively, for an average of .275. I am very much a novice shooter, and for a factory rifle, I am pretty darned satisfied with that result. My next move, I guess, is to attempt to back engineer the cartridge and see if I can replicate it.
