Abstract
A hollow-charge projectile is provided with a precision charge (12) which, on the one hand, is surrounded on the outside by a metallic jacket (11) and, on the other hand, is lined on the inside with an insert (13). During assembly there exists the danger of formation, due to thermal expansion, of cracks, cavities or fissures between the three components (11, 12, 13). This is avoided by first cooling down the precision charge (12), heating the jacket (11) and introducing the precision charge (12) into the jacket (11), and by subsequently heating the jacketed precision charge (12), cooling the insert (13) and pressing the insert into the precision charge (12). The thus assembled components (11, 12, 13) are brought to room temperature.
