I agree that using a shot drop tube like a MEC loader has on it is supposed to keep the wad's shot cup pushed out tight with the hull -- but, it just does not do that. Take a look in the end of your 1 1/8 oz. loads and see what is going on, before you start the crimp. Downrange will have shot on the outside of the shot cup pedals. It is just the way Downrange Wads are made.
