I would recommend a classic express rifle style bolt action Mauser in 375 H&H or 416 Remington for general use and dangerous game hunting. If a person were dead set on a double rifle of larger caliber, I’d say you couldn’t really go wrong with a 450/400 3”, 450 3.25”, 470 3.25”, or 500 3” as long as it fits you well and is of sufficient weight for caliber. Anyone can learn to shoot these rifles if they are motivated.
