Projectile ( 10 ) is for use with barrel assemblies of the type having a plurality of axially disposed projectiles within a bore and wherein discrete propellant charges are provided for propelling respective projectiles sequentially from the bore. Projectile ( 10 ) comprises expandable sleeve ( 11 ) encircling at least part of core ( 12 ). Sleeve ( 11 ) and core ( 12 ) have wedging surfaces ( 14 ) operable to deform trailing part ( 21 ) of sleeve ( 11 ) into sealing engagement with the bore in response to pressures exerted on projectile ( 10 ). When projectiles ( 10 ) are axially disposed in the bore, rear face ( 24 ) of the leading projectile cooperates with leading face ( 20 ) of the trailing projectile to define a discrete space about spine ( 23 ) for receipt of the propellant charge. Sleeve ( 11 ) is retained about core ( 12 ) during travel to the target. |
