An apparatus is provided for the loading and automatic firing in a weapon of an ammunition unit provided with a sabot without consequential deterioration of the ballistics of the ammunition unit. The apparatus comprises a unit consisting of a number of prismatic or cuneiform elements which together form a rotationally symmetrical body with an external surface. This surface is truncated or curved and flares rearwardly from its leading portion. The apparatus also comprises an enclosing device for enclosing these elements at the trailing portions of the body, and unifying the elements on loading of the ammunition unit into the barrel of the weapon. The enclosing device also encloses the leading portions of the sabot. This device is arranged to burst on movement of the ammunition unit in the barrel. The elements will namely execute flip movements about their trailing portions which are defined by the inner wall of the barrel and entail that rotationally symmetrical body is splayed forwardly, which facilitates parting of the elements with the aid of aerodynamic forces on departure of the unit from the barrel.
