A barrel assembly for a weapon, said barrel assembly including a barrel; a plurality of projectile assemblies axially disposed in end to end abutting relationship within said barrel for operative sealing engagement with the bore of the barrel, each projectile including a projectile head and an integral cylindrical spacer portion extending axially and rearwardly from said projectile head; discrete propellant charges accommodated within said cylindrical spacer portion for propelling respective projectile assemblies sequentially through the muzzle of the barrel; ignition means for igniting said discrete propellant charges; and control means for selectively and sequentially actuating the ignition means. In one form, each projectile assembly further includes an internal wedging surface, at or adjacent the trailing end of said cylindrical extension which accommodates a tapered nose part of a following projectile, for expanding said trailing end into enhanced sealing engagement with the barrel upon engagement of said wedging surface with said tapered nose part.
1-23. (canceled)
A projectile for a barrel assembly containing multiple projectiles, having a nose and an expandable tail, wherein when the projectile is stacked nose to tail in a barrel with other projectiles and force is exerted down the barrel, the tail contacts the nose of a trailing projectile and part of the tail of the projectile is thereby expanded into sealing contact with the bore of the barrel.
A method of sealing a projectile in a barrel, including:
A barrel assembly having a barrel with a plurality of projectiles aligned nose to tail for sequential firing from the barrel, each projectile having a nose, a tail and a propellant charge, part of each projectile having been expanded into contact with the bore of the barrel by interaction of the tail with the nose of a trailing projectile.
