Abstract
A pneumatically-operated ball projecting device is provided wherein the muzzle velocity of the projected ball is determined by a pneumatically-operated detent in the barrel of the device. The detent holds the ball within the barrel until a predetermined air pressure is built up behind the ball, causing the detent to collapse, permitting the ball to be projected out of the barrel. Varying the pressure required to collapse the detent directly varies the muzzle velocity.
