The rifled barrel of the gun imparts a high spin rate to the discs which gives them dynamic stability in flight. Acceleration along the gun barrel separates the discs. The discs are effective throughout their entire air borne range, as a result of their spin energy in addition to their forward velocity at target impact. The serrated edges of the spinning discs are capable of producing severe flesh wounds even at low strike velocities. | |
