I was using a Ruger 77/50, 85gr FFFg T7, 250 gr SST, Harvester short black sabot, CCI #11 cap and Nikon ProStaff 2-7x32mm. When I put in the time, I get good groups but that was the best ever. I had to walk up to the target to figure out where they went cause my cheap spotting scope could not focus well enough. On a good day, that rifle and I can keep them around an inch at 100 yards.
