    Abstract: A barrel assembly for insertion into a parent barrel of a gun wherein said barrel assembly has a plurality of projectiles axially disposed within at least one barrel of said barrel assembly and associated with discrete selectively ignitable propellant charges for propelling the projectiles from said at least one barrel wherein said barrel assembly includes a parent barrel engaging means. The barrel is suitably provided in a removable rear barrel section having engagement means for operatively aligning the rear barrel section with a forward barrel extension. Spare rear barrel sections may be stored in a stock of the gun and automatically fed into alignment upon exhaustion of the projectiles in the barrel.

    Abstract: A cartridge assembly (10) for firearms or weapons, said cartridge assembly including a support body (11) having a central longitudinal channel (16) housing a plurality of projectiles (20, 22, 24) in end-to-end orientation and having a plurality of circumferential chambers (14), wherein each chamber houses (14a, 14b, 14c) at least one propellant charge (12a, 12b, 12c) and is located adjacent to a respective projectile; fluid communication means (18) included in the support body for communicating the products of a gaseous expansion of said propellant from a respective chamber (14) into said central longitudinal channel (16); whereby, upon initiation of a selected propellant charge (12a, 12b, 12c), the communicated products of gaseous expansion from a circumferential chamber force or eject a respective projectile (20, 22, 24) from the cartridge assembly (10). The propellant charges may comprise a volume of propellant material encased in a bag with an igniter.

    Abstract: A projectile sealing arrangement for a barrel assembly of a weapon wherein a plurality of projectile assemblies (10) are axially disposed in abutting relationship within a barrel (20), each projectile assembly (10) including a body (11) associated with a discrete propellant charge (15); said sealing arrangement comprising rearward opening (13) communicating with cavity (14) provided in said projectile assembly (10) for retaining the discrete propellant charge (15) and a forward portion (16) of an abutting projectile arranged for operative sealing engagement with a complementary portion (17) of the rearward opening (13). The sealing arrangement suitably includes surface portions of complementary shapes such that, during application of a compressive load (L) to abutting projectile assemblies (10), discrete propellant charge (15) is sealed within the cavity (14).There is also disclosed and claimed a chain of individual projectiles connected head to ta il by complementary spigot and socket members.
