Since I first went to Africa in 1978, I've hunted with something like 20 PHs, and not one of them used a double rifle. Every one of them carried a bolt gun of .375 H&H on up. Part of it, of course, is the scrotum-shriveling expense of a decent double rifle, and the other part I got a look at last Saturday, when the club I belong to staged its annual African shoot. There are three events: running lion, rising buffalo, and standing elephant. The first is as many shots as you can manage, the second six, and the third five, and you have only a few seconds to get off each round.
