jmho I use hard cast. got more than I'll need for years to come ( ok I'm cheap) and they do what i need doing. I have not shot a moose or have any want to do so. I have been in on a few of moose recoveries. Moose are stupid and spiteful. Too stupid to fall down and when they know they are about to they make a beeline to the thickest nastiest wettest spot for mile around. Then you get to spend all day and half the night, destroying 2 chainsaws, a 4 wheeler and a couple of 4x4 trucks till you get to the point of " I should have just sat down and eaten the S.O.B. in place." WE'RE HAVING FUN NOW !
And that is precisely why you need to put them down right now. None of that one-shot necessary nonsense. The moose needs to be shot until it crashes to mother earth and unable to get up on its own accord. I remember my guide in Maine telling me to empty my revolver in the moose and make sure it doesn't head into the swamp as that is where it's going if not killed quickly.
