Based on experiences in the african bush, research with dummies and theoretical investigations a dicussion is presented on the suitability of the big game cartridges (factory loads and wildcats) for hunting dangerous game in africa. It is shown that an improved .458 long cartridge, e.g. .458 Lott, .450 Watts, .450 Ackley, is highly recommended with respect to efficiency, penetration, availability of bullets, loads for big game and also plains game. These cartridges offer easy reloading and affordable rifles by converting and customizing normal equipment. The mechanism of bullet penetration in game and a new concept: the SuperPenetrator is presented. Other topics are: elephant hunting; hunting areas in africa; bullet recommendation; value of indexes.
