If you look at Fed Prem group 1,you have 3, 3/4" groups within the overall mess. Shots 2,3,4. Shots 5,6+7 are almost identical to them. And shots 8,9 + 10 are also 3/4" and not too bad for zero. If you had shot either of those by themselves,especially the last 3 shots,you would feel pretty good about things. Possibly from a good rest you could print 3/4" 3 shot groups,with factory fodder no less. That particular target sure looks to me like you were inconsistently bedding the rifle at the bench.
