If it takes a 577 NE to hunt a 150 lb. African leopard, then what's it take for a 12,000 African elephant?

I've got the feeling that this 577/12 gauge idea isn't exactly founded upon on a background of actually hunting leopard. Client-hunters almost never wade into the brush in order to hunt leopard, and PHs only do so themselves when a client wounds one. The VAST, VAST majority of these hunts involve baited cats that are shot early and late in the day out of trees, and again, the precise, scoped, bolt-gun of moderate caliber is tailor-made for this sort of hunting. Some big double would be more of a hindrance than a help, and might actually lead to someone getting badly hurt............
