The question real boils down to how many safaris will you be going on in your life time? My guess you will be shooting more White Tail sized game in your life time than anything else and with the costs of hunting in Africa and in general, buying a second rifle is not a major expense. Buy a good 30-06 or 7mm RM and yea it will be a little to much for some and a little light for others but it will get the job done, the 7 x 57 is a good one, but its pretty much a hand loaders deal these days, as for brown bear and such, that too is maybe once in a life time for most!
