I don't understand the point of one for Africa. However cartridges like the Weatherbys, the .330 Dakota etc how much different is the velocities for these sorts of cartridges.

No doubt a 300 gr .338 could kill buffalo, elephatn etc

A wankie sniper looking rifle, no way. A nice safari classic .338 Lapua with say a 26 inch barrel, who would notice the difference?

So why not a .50 BMG for Africa?!
