Sleeved projectiles

Abstract

A projectile (10) is for use with barrel assemblies of thetype having a plurality of projectiles axially disposed within a barrel havinga bore and a muzzle and which projectiles are associated with discretepropellant charges for propelling said projectiles sequentially through themuzzle of the barrel. Projectile (10) comprises expandable sleeve (11) encirclingat least part of core (12). Sleeve (11) and core (12) have wedging surfaces(14) operable to deform trailing part (21) of sleeve (11) into sealingengagement with the bore in response to pressure exerted on the projectile(10). When projectiles (10) are axially disposed in the bore, rear face (24) ofthe leading projectile cooperates with leading face (20) of the trailingprojectile to define a discrete space about spine (23) for receipt of thepropellant charge. Sleeve (11) is retained about the core (12) during travel tothe target.
