Fond as I am of the .338/06's ancestor, the .318 Westley Richards, I must admit that for practicality's sake, the 9.3 is the better choice. Ammunition availability, though far from universal, is much better. The bullet choice is just as outstanding as the .338. You will get basically the same number of rounds in the magazine with either one and for both North American and African game the greater punch of the 9.3 will be greatly appreciated around big bears, big antelopes and the occasional big problem. Admittedly, for a safari rifle I consider it a "heavy light". In the hands of a truly exceptional shot it will do as a World Rifle like the sainted .375 H&H, though I would be reluctant to use it as such. However, for the bulk of the planet's hunting where 250 kg animals are the norm (or at least really common), it's hard to beat.
