This is the original and still widely read and highly regarded book on internal and external ballistics. Dr. Mann was a tireless experimenter and had the resources to pursue his interest with the best equipment available. A close friend of Harry Pope as well as other notable experimenters in the early days of smokeless powder, Mann's work is thorough and well documented. If you have an interest in ballistics, this is the foundation that you must know in order to understand the ensuing century of work in that field.
