This report details the study effort and testing conducted to design a more optimum rifling profile for the Advanced Medium Caliber Aircraft Weapon System AMCAWS 30MM ammunition. Several critical parameters such as bearing stress and torque have been identified and their importance to the ultimate survivability of the band assessed. These critical parameters have been incorporated into a preliminary model to predict the success or failure of a given band and barrel combination.
