I've seen a few threads about the book from other guys on this site talking about the book, and I do know that all the pictures and info on the website
www.dougstewartauthor.com is directly from the book, it covers a lot of different topics, proper fit, correct shot size, working with dogs, birds, stories, etc.. is there something specific you're looking to learn more about or interested in? Let me know and Ill let you know if the book covers it.
