out to 500 yds the trajectories were never more than a few inches apart. Beyond that range trajectory and time of flight did start to differ more. The Hispano and the .50 Browning were probably one of the better match ups as far as trajectory and time of flight go.

Thank you for this table and comparison. The main purpose of the 20 mm cannon installation was to keep the German fighters away in a longer distance yet before they were able to open an effective fire.
