But they're not hunted with firearms, are you an RN or a lawyer?
It's not really a matter of too much for the deer but potentially too much for the shooter. I love all kinds of big bores but for me, they must be practical first. I just don't consider a 7lb revolver to be very practical. All I suggested is that if you don't "need" the range, you might not "want" to deal with the weight/blast/expense.
