<p>The invention provides a device for controlling a ball-shaped projectile's trajectory by propelling the projectile at an angle to the gravitational force upon discharge from a barrel including an O-ring. The barrel has a center axis directly and fully offset relative to and above the shared center axis of a chamber and O-ring located at one end of the barrel. Upon firing, the projectile spins directly up a small bevel on the lower inner edge of the chamber-end of the barrel, thus being projected diagonally into the barrel, the bore large enough to provide clearance between it and the projectile. The projectile has consistent and unimpeded rotational acceleration through the upper portion of the barrel which is ensured by air pressure escaping around the projectile and, via the bevel, along the lower surface of the barrel.</p> |
