I have a friend that has decided he wants to use my 460 on a hunt in Africa. for Cape buffalo,Hippo,Crocks and Lion. He has decided after talking to the PH that bullets in the 450-500 class will work best. So i'm thinking that the 450 and 500 gr Barnes Triple shocks might work pretty well I've got about 7 lbs of VV-550 that I think would work well in this case. Anybody have any helpfull info on the load data?
