I think you are thinking of 2 different things. There is the pour and then the compression. Compressing the powder is not the same as beating on the butt to unsettle powder.I like to push till bottom.. then give it my shoulder weight for packing. A few packing rod drops to feel is down nothing crazy.. just to feel bottom.
I don't know what's better... im more about whatever as long as it's down all the way.. most my packing is just checking that it feels seated.
I've seen some people on video pick the rod up and throw drop it down hard on the wads packing.
