An Analysis of Various Primer Vent Configurations in 5.56 mm Ammunition,
Abstract
Statistical techniques were used to determine the ballistic effect of various primer vent configurations in 5.56 mm ammunition. The results indicate that the 5.56 mm standardized primer vent provides the most efficient ballistic system, i.e., the highest velocity-pressure ratio, of all vent configurations tested. It was also shown that velocity, chamber pressure, action time, propellant ignition time, temperature coefficient of velocity and the temperature coefficient of chamber pressure are affected by a change in primer vent cross-sectional area.
