Call me prudent.....the body of the case is already up to spec. so it shouldn't be worked by the FL die. Are these the same brand of cases that you worked up your "above max. load" in? I make it a point to not work above max. unless it is a cart. that is loaded way below max. I just don't like what you're doing with max. loads new cases or not. I seldom get my best accuracy with near max. loads. When dealing with max. pressure, a hot day can put you further over and you could get into press. trouble, if out hunting, you could get a case stuck in the chamber or a case separation, tying up your gun, while bullwinkle runs to the next province. I'd fall back and regroup IMHO....
