Tony Sanchez is nearing his sixtieth year as a hunter in Africa, a record that is hard to equal. As might be expected from a man who likes the 'big' in big game, this book starts with the .375 and works its way up to the .700. All calibres in between are covered, which he breaks down into the calibres for bolt actions (a total of 16 calibres) and the rimmed cartridges for double rifles (a total of 14 calibres). He likes doubles as much as bolt actions, and it is refreshing to see no bias in his approach to these completely different types of weapons. He tells us which bullets and which actions work and which ones do not. With an almost unbelievable amount of elephant, lion and buffalo kills to his name, he can justly be said to have more experience with 'the African calibres' on dangerous game than any other person alive.
