My brother gave me an old book called "Textbook of Pistols and Revolvers" by MAJ Julian Hatcher. Hatcher wrote this book through the years 1934-1935. The content includes the introduction of the S&W .357 Magnum and essays about barrel leading, lead alloys, powder burn rates, early electronic chronographs, early chamber pressure devices and mathematical equations that support such devices.
There are (obviously) outdated data- and some misleading. But in 1935 Hatcher seems to have had a good grasp on the issues we discuss here each day. Has anyone read this book.....or books like it? We're not 'all that' in our 'modern enlightenment' as we may think- Hatcher wrote this 80 years ago. I'm impressed.
