I could not choose for my buff hunt in 2013, so I took my 375 H&H and my 416 Rigby. Always good to have a spare gun...

i would strongly recommend having two guns. things happen... scopes can break or lose zero, scope rings can break, and ammunition can get ruined or lost. having one or both rifles set up to use iron sights is also a good plan.
a good combo in my opinion would be one medium bore and one large bore. example: 375 H&H and a 458 Lott. this way both rifles are legal for DG in the event your large bore gun has trouble. both the 375 and 416 are perfectly capable of taking PG if loaded with lighter bullets.
