Abstract: The U.S. Army Research Laboratory (ARL) has many requirements to test projectiles in excess of their normal muzzle velocities or maximum powder loads, particularly to determine comparative ballistic performance. ARLs existing 7.62-mm (0.30-cal.) bore guns are not capable of launching the 7.62-mm (0.30-cal.) fragment-simulating projectile above 1350 m/s. Since testing requirements often exceed 1500 m/s, a custom chamber system was designed and successfully tested to fulfill this need.
