him,and guys have taken elephant (and everything else) wth a .44 mag revolver,and308 is twice as powerful as a .44, and 308 autorifle has twice the repeat hit speed of the .44, and 4x the repeat hit speed of the Mauser 7x57, with which Bell took many hundreds of elephant. Obviously, then, the 308 is plenty of rifle for anything, if you are even half man enough.
