I"ve culled over 100 of the darn things from rancher/friends that hated the darn things and wanted them gone in the Trans Pecos region of W TX. Primarily used 7mag, 7-08, and even a 30/30 several times just to see how well it worked. As GregW and Ingwe said, any good bullet in the right spot takes care of business, just like any other animal. Their mythical "toughness" reputation, just like other African plains game I've shot, was greatly exaggerated.
