I loaned my .44 mag. lever gun to a friend, he brought down a whitetail at 50 yards with one shot of XTP.
However, Elmer Keith liked the hard cast SWC. Who is to argue.
Basic thing with a pistol round is do not try to overextend the range. It is still a pistol round. Unless you have practiced extensively and know it's drop, do not try over about 50 yards.
