I'd say .375 or bigger and 4000 ft-lbs and premium softs (A-Frame, TBBC family, Northfork). 0.300 sectional density. That's specifically for bear - AFAIK there are no elk in Africa.
It's a continuum of course. Can you use a .30-06? It's way better than what Mark had (his client had the Glock 10mm apparently) but worse that the above. It'll do better if you use premium 200+gr bullets. But if you get to pick, the .30-06 is not the best thing to pick.
