Recently purchased a 1982 model 70 in 270win and started developing a load for it. Did my ladder test, picked the rounds that shot tightest eliminated the outliers and procedded to shoot a five round grouping with each potential powder wieght. The tightest of these potential recipes was 52gn with 145gn eld-x bullets. The problem was the gouping was split (see picture). 3 tight rounds on the right shot first and last 2 on the left. Was hoping someone could tell me what this means? Is this most likely human error, maybe the rifle bedding was loose? Im thinking the round is in tune with the rifle but maybe an outside factore effected the shots. All other recipes in this test shot 1moa or over. Usually i shoot sub moa with my other rifle.
Thanks
