A projectile and a method of launching a projectile from a barrel. The projectile of the present invention may be matched to a pre-selected barrel rifling to produce a controlled spin rate. Controlled spin rate is characterized by substantially balanced forward and axial deceleration. Substantially balanced forward and axial deceleration is characterized by an axial speed that decreases in relationship to the decrease in forward speed. Substantially balanced forward and axial deceleration produces a trajectory that is characterized by a gyroscopic stability factor that remains highly stable over a given distance of a trajectory. Gyroscopic stability is controlled during the projectile's flight by controlling the spin damping moment as a design element. Control of the spin damping moment may be achieved by incorporating physical features in the projectile's design and manufacture and/or may result from the incorporation of physical features imparted upon the projectile during launch.
