A system for propelling an air-driven projectile from an air gun includes an air gun with an elongate bore and a source of compressed air in fluid communication with the elongate bore. An elongate projectile is disposed within the bore of the air gun, the elongate projectile having an outer diameter that is less than an inner diameter of the elongate bore, wherein the elongate projectile has a length that is at least substantially equivalent to a length of the elongate bore of the air gun. The elongate projectile has a butt on a proximal end of the projectile and a tip on a distal end of the projectile, wherein the butt comprises an outer diameter that is greater than an outer diameter of the elongate projectile and less than the inner diameter of the elongate bore. |
