My friend goes over there twice a year, and shoots nosler b-tips out of a 30 hart/7mm hart, and has almost all game drop in its tracks!, on bigger game he has stuck with the triple shocks, and swift a-frames, in bigger bore guns! with great sucess!, bullet placement is more important than the bullet on the smaller game animals! he has used the b-tips on Zebras, and says they drop in there tracks!, has a Full size mounted one in his living room!, along with a ton of other animals!
good luck, on your hunt!
