Abstract
Abstract A hollow charge with an insert of progressive and degressive wall thickness, respectively, wherein the insert has at least partly curved generating lines. The oppositely disposed outer and inner generating lines of the insert have the same line course, yet are rotatably displaced relative to each other for a predetermined angle within a sectional plane.
