Try Robert Ruark:
After 1950, Ruark began spending time in Africa, publishing Horn of the Hunter: The Story of an African Hunt (1953), about an African safari, and Something of Value (1955). Based on the Mau-Mau uprisings against British colonialists, this latter book took its title from an old Basuto proverb: "If a man does away with his traditional way of living and throws away his good customs, he had better first make certain that he has something of value to replace them." The book was a major success, earning the author more than a million dollars from royalties and the film rights.
Or James Rand. Run For The Trees
Description: The savage adventure of two lusty giants struggling for possession of an incredible African slave empire
Comments: Despite the above description there a great amount of hunting/adventure included. However Shooting lions with a Thompson SMG may not be to your liking.
