A projectile ( 10 ) is for use with barrel assemblies of the type having a plurality of projectiles axially disposed within a barrel having a bore and a muzzle and which projectiles are associated with discrete propellant charges for propelling said projectiles sequentially through the muzzle of the barrel. 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 pressure exerted on the 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 the core ( 12 ) during travel to the target.
