I have not read the book you champion treblig1958. However, looking at the synopsis, I would say it doesn't quite address Gr8days original request, which seemed to be for recommended books about English guns, as opposed to good hunting stories.

Your book sounds interesting: "Five years of a hunter's life in the far interior of South Africa. With notices of the native tribes, and anecdotes of the chase of the lion, elephant, hippopotamus, giraffe, rhinoceros, &c" Not much mention about the history, development, patents, technological advances over several decades and so on that I suspect was what was behind the request.

Either way, I shall have to get 'your' book and read it for myself if it is as good as you say!
