Abstract
An improved paintball and gun therefor cooperate so that the range of the paintball and its accuracy are significantly improved. The external surface of the paintball is contoured so as to increase frictional interaction with air, and the barrel of the paintball gun interacts differentially with the upper and lower hemispheres of the ball so that significant backspin is imparted to the paintball. Accordingly, the paintball experiences lift in flight which substantially increases its range and accuracy. The interaction of the ball with the barrel may be wholly aerodynamic. The interior of the paintball is preferably baffled so that paint therein rotates with the shell, preventing the backspin from being damped out rapidly.
