RE: Guns and loads for Africa.
I'd want a beefed up Mauser action in 416 Rigby and my second rifle would be the same action but in 375 H&H.
Both with solid one piece scope mounts with irons also on the rifles. The irons would not be for use unless the scopes malfuntioned.
But, I'll never go to Africa to hunt. Just ain't in the cards for me.
