You can deduce from the previous posts that bigger is better, as long as you can shoot it well... lots of experience above. You have also learned, what everyone before you discovered... once you hunt Africa, it gets in your blood and you will be plotting and planning a return as soon as you get home!
Something yet to be clearly articulated, at least in what I have read above, is the difference between "Hunting" a buffalo, and "Tracking" a wounded buffalo. For hunting, any legal cartridge with proper bullets (A-Frame, TSX, Bonded Woodleigh's, TBBC's etc...) will work. If you end up in a scenario, like the one described by Longwalker, above, I would prefer to not be carrying the bare minimum, although in a charge scenario, you will not be the only one shooting, in fact, you may not even get off a shot before it is all over... even still, I am a fan of a versatile, handy .458... in Carbine form. The "little" .458 Win Mag, will do pretty much as well as the Lott when set-up properly... I have both. My Lott is in a heavy RSM, which is less wieldy than the Win Mag Carbine that was purpose built for your exact scenario, which, for the time being is whacking bears prior to its journey to Zim. The scope is an illuminated 2-7, with a good field of view and is very quick to get on target... it also pops off in 5 seconds and the irons are sighted at 50 yards, but just as good at 5. Building what you want is a reasonable and relatively affordable option.
