The simple truth is that ordinary “deer” cartridges in the hands of ordinary hunters work to terminate ordinary African game. African farmers, ranchers and sportsmen have been hunting native impala, oryx, blesbok, warthogs, kudu, wildebeest, waterbuck, and all the rest (even buffalo, lion, and elephant) with medium caliber, medium power cartridges for more than a century. We’d consider many of them perfect for whitetails, mule deer, caribou, elk, and moose. Like most pragmatic country folk, Africans make do with inexpensive rifles shooting inexpensive, commonly available ammunition in average cartridges such as .303 British, .30-06 Springfield, and 7x57mm Mauser. Which strongly suggests we visitors might succeed in Africa with our own deer and elk rifles.
