Dixie, I agree. That was one of my thoughts. But what could be settling. Everything is tight. I know the action and bed are clean and tight. I'm wondering if the action is still trying to, for lack of better term, settle into the aluminum beading in the stock. I was beginning to wonder if there may be factory crud in the threads of the barrel and action but it "seem" to be tight and I believe it would cause a constant inconsistency in accuracy. In fact with 168 gr. SMK it was not grouping well. 175 gr. SMK took care of that concern.
