ABSTRACT:
A hollow charge for causing a primary effect by making a hole in a target (1) and a secondary effect by charge material emanating into the target via this hole (1a) and causing a sudden pressure rise, fire, fragmentation, poison or a corresponding damaging effect within the target. The charge comprises a cavity (9) expanding in the burst direction and covered with a metal layer (10). At the initiation of the charge a forward directed penetrating jet (2) having a high velocity (v.sub.1, v.sub.2) is generated and also a slug (3) with a comparatively low velocity (v.sub.3). The charge further comprises an additional body (11) in front of or integrated with the metal layer for generating a separate jet part (4) at the initiation of the charge, which part (4) follows behind the penetrating jet (2) and is included in the charge material causing the secondary effect. The additional body is arranged in such a way that the separate jet part (4) is in front of and separated from the slug and has a velocity which is well above the slug velocity (v.sub.3).
