Abstract:

Calculations were made to determine the conditions necessary in order to obtain 4000 ftsec in a cal. .50 gun. It was found that a pressure of 87,700 lbsquare inches and a powder potential of 1,805,000 ft lblb would be required to produce this velocity in a 45-inch barrel. Calculations have also been made for other barrel lengths and a pressure of 80,000 lbsquare inches. The method of calculation is presented in detail. Author
