American method and comparison of the different methods of internal ballistics

Abstract

Le Duc's method gave good results in almost all cases. But in all cases American ammunition was used in American guns and it is doubtful if the method would give equally good results when applied to British guns or British propellants. The advantage of Le Duc's method, however, in its simplicity compared with the other theoretical methods and the quickness with which results can be calculated by this method.
