RE: Only one caliber for the rest of your life.
Only one gun for everything,[:@][:' (] I would have to go with the .338 WIN. I could load it down for smaller game and still be able to hunt everything except for the cape buffalo. I think it would be able to cover a much broader range of animals better than the 30-06 and I would " feel" better having a bigger slug if I were to hunt grizzlies.
