After repeat borrowing the first edition of this book from my local library, I was thrilled when this 4th edition became available. Sam Fadala answers more questions I had in this edition than in the previous ones. I personally could have done without the chapter on hunting. But at the same time I did appreciate the chapter about the historical background of the big-bore guns. The only improvement I would like to see is a chapter about "kit guns". I.E. who might consider buying a gun this way, which skills are essential and what are the pitfalls.Overall I find this book very informative. The chapters are organized in a fashion that make it your choice if you'd like to read up on a single topic or read this work front to back. Judging by the used prices for the first edition, this book was a classic a while back and to me it has become a "must read" item for anyone who considers getting into the black powder thing. Thanks, Sam Fadala!
