If I had to shed my safe contents with the exception of three (not counting rim fires or shotguns), it'd be difficult but if I was practical I'd go with my Blaser R93 with scoped barrels in .25-06, ,30-06, and .375 H&H.

The alternative grouping would be 223 AI, .284 (as much for the rifle it's in as the cartridge), .375 H&H.
