That's good grouping Grouse. But quite frankly I don't seen any problem with the way the CVA shot either, even with the delay. Perfectly acceptable hunting accuracy for most PA hunting situations (except open field). That bullet should work fine.
But I'm sorry but I do have to say something about your comment about not using it in PA except maybe for doe. That comment makes one think you believe a doe's life is not equal to that of a buck's! I don't think that's what you meant at all but that's what it sounds like.
But in any event, IMO either rifle is easily capable of a clean humane kill up to 100 yards and beyond.
