There are some game in Africa that you either can't or it's inappropriate to not use a magnum. It's fine to say use medium calibers (medium meaning .270's, .308 etc in this context) on bigger game, but if you don't get used to using bigger calibers such as .375 H & H on game, then it makes it that much more difficult when you do need to shoot something with a big caliber. Secondly, if you do not like to twist turrets, the magnums can help (provided you can shoot them ok) when the large game are a long way out...more so in places other than Africa.
