Abstract

A munitions round for a subcaliber projectile to be fired from a barrel-type weapon has a casing, of a uniform outer cross section substantially over its entire length, receiving the projectile which is at least partially surrounded by the gas-generating propellant charge. A drive body is mounted at the forward end of the projectile and has a rearward pressure-receiving surface which droops inwardly toward the projectile from an outer edge of the body which is engaged by the casing. The body is formed from a plurality of segments which form-fittingly hug the projectile and have confronting angularly spaced separating surfaces bridged by a sealing member. The forward end of the body, formed by the segments, is concave forwardly and has a leading edge which is disposed outwardly and axially ahead of the rearward inner edge of this surface which forms a pocket engaging the air upon propulsion of the projectile from the barrel to effect separation of the segments and dislodgment of the body.
