I've just finished his book, "my outdoor life", really enjoyed it, well worth reading.
He likes the Blaser R8 and favours .416 Remington magnum when around dangerous game...just a couple of snippets from the book.
Also he was on the last Desert Island Discs on radio 4. It was nice to hear someone down to earth on that, so often they have academics or arty farty folk.
You can catch up on that and others on this site. It's interesting to delve into that, "Andy McNab" was good on it too.
