Abstract

A ram head for possibly two-part ammunition which is provided at its bottom with a central rotationally symmetrical form-locking zone. In order to be able to unload the ammunition, a housing (1) is provided with a ring (11) that is arranged to be axially displaceable therein and is provided with a plurality of radially pivotally articulated extraction levers (12), with the extraction levers (12) being spreadable against a spring bias by a plunger (25). The ring is coupled with a slide sleeve (22) that is provided with a centering ring (23) having a shape corresponding to the form locking zone of the ammunition and the axial movement of the ring (11) and of the plunger (25) is controllable by an eccentric shaft (8) mounted on the housing.
