This volume by noted sixgun aficionado John Taffin covers the truly Big Bore revolvers from the first .357 magnums, .45 Colt, and .44 Specials to the brutal .500 Maximums. Although the title suggest otherwise, many of these very large caliber revolvers actually were of 5 shot capacity, because the cylinders needed the extra thickness this configuration provided. In these 336 pages are stories of the history of big revolvers, modern day big bores, custom big bores, shooting bog bores, hunting with big bores, and some other stuff, such as choosing the proper holster and ammunition. There are many good photos of some exceptional guns, and references to help you find out even more, should the urge hit you, as it probably will.
Mr. Taffin is a long-time writer for American Handgunner and Guns magazines, as well as a book author of some renown, and tells his tales from personal experience. Personally, I have this book in hard cover for at home, and on my Kindle for deer stand reading.
Give this one a try also (or see my review).
