Abstract
An improved paintball gun having significantly improved range and accuracy. The barrel of the paintball gun is formed so that the compressed gas expelling the ball from the barrel exerts differential aerodynamic forces on upper and lower hemispheres of the ball, imparting significant backspin to the paintball. Accordingly, the paintball experiences lift in flight, substantially increasing 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. The surface of the paintball may be contoured to control its aerodynamic characteristics.
