22 rimfire--as stated--cheap to shoot
220 Swift for varmints, small game--anthing up to and through deer and still the ultimate p-dog gun
300 or 338 Win mag--for larger plains game, elk, moose, etc..
375 H&H or 416 for Africa--personally I would take the 416--
12 gauge shotgun--needed to hunt pheasants, ducks, etc..

I have used the 300 and 416 battery on several trips to Africa and have been very, very pleased--in fact my next trip I plan to take 3-excessive I know--but I plan to take a 338, 416 and 470 Nitro--some might say why?? because I can...
