I know diddly about hunting Africa.
I do know, with buckhorns it is easy to shoot high under stress. If I were setting up a rifle for irons (I have a couple set up that way), it's a ghost ring rear and fiber optic front, all the way. That works much better- for me.
(I shot buckhorns my whole childhood, so it was an unpleasant surprise for me to find out that push come to shove, I wasn't as good at getting that post into that notch as I thought I was, under stress...)
