Something to keep in mind: Taylor, Bell, Blixen, Sutherland, and others who killed thousands of elephants professionally preferred, believe it or not, 318 Westley Richards with its puny 250 gr .330 bullet. Wally Johnson spent a lifetime hunting elephants with his Model 70 in 375 H&H and Harry Selby advised 416 Rigby as a stopper for PHs and 375 for clients. And all would have been shooting old fashioned bullets and powder technology (though admittedly solids tech probably hasn't changed that much). Furthermore, all but Johnson would have been shooting standard action Mauser rifles, not double rifles (Selby's 416 was built on a standard action, though typically they are on magnum action, and Johnson's rifle was almost certainly magnum length).
Moral of the story: Don't overthink it ... unless you want to. We all need a hobby.
