The tubular shell comprises: a casing having a fuse-carrying forward portion, a substantially cylindrical intermediate portion formed with an inside undercut delimited by a rear shoulder and a front shoulder, and a tapered rear portion; a base plug received in the rear portion; at least three pre-formed, rigid segments of a cylindrical liner, received in the undercut so that they abut both shoulders, each segment being of a cross-section smaller than the aperture of the casing in its rear portion. The backs of the segments are relieved to provide desired weight and/or other inertial properties. A narrow wedge is used as a final restraining segment.
