Yes.
Possibly the .460 Weatherby Magnum, the .577 T-Rex, or the .700 Nitro Express.
Never deviate from published reloading data. You risk injury or death if you do.
460, no. 470, yes. See the Hornady website, where they list current production ammo.

There are thousands of elephant cartridges out there from bore diameters ranging from .366 all the way to 1.2 inch bores. The most popular is the 375 H&H, but I have seen elephants soak up 10 or more rounds of 375 weatherby so here is a very, VERY short list of the most famous elephant cartridges of all time... 375 H&H Magnum Nitro Express 416 Rigby Nitro Express 450 Nitro Express 470 Nitro Express 505 Gibbs Nitro Express 577 Nitro Express 600 Nitro Express and last but not least the mighty 4 Bore blackpowder I would recommend the 416 rigby as an absolute minimum
The 475 Nitro is a low pressure cartridge. The 460 Weatherby is a high pressure cartridge. They use different powders. No, you cannot reload a 475 Nitro to 460 pressures because a gun chambered for 475 would not take the higher pressure.
No, the .600 Nitro Express is more powerful. Also, there is a .700 Nitro Express round that is designed for a rifle, but there is one handgun that will fire it.
Elephants have been traditionally hunted with bolt action rifles, most of which were either military or derived from military designs, or with purpose-made African game rifles such as high-end double rifles from manufacturers such as Holland & Holland.Common military calibers from the colonial times in Africa were 7mm Mauser (7x57) and .303 British. Hunters today no longer favor those and generally use the larger calibers made just for hunting.Common specialty hunting calibers are 9.3x64, .375 H&H Magnum, .404 Jeffery, .416 Rigby, .450 Nitro Express, .458 Winchester Magnum, .458 Lott, .460 Weatherby Magnum, .470 Nitro Express and .500 Nitro Express. .600 Nitro Express and .700 Nitro Express are also not unheard of.Poachers not concerned with ethics of hunting may use any of the myriad surplus military arms floating around Africa from the many conflicts. This can literally be any caliber from 7.62x54 to .308 to 8mm Lebel.
Largest standard caliber is likely the S&W .500 Magnum, but revolvers HAVE been built in .600 Nitro Express.
.700 Nitro Express
