摘要
A dummy shell for practice ammunition has external dimensions substantially equal to dimensions of a corresponding shell for live ammunition of a same caliber provided with explosive charge and detonating fuse, the dummy shell for practice ammunition comprising a single-piece metal ogival body (1) having a bottom (2) and a side wall (3) defining an inner cavity (4) having an apical opening (5). The side wall (3) and the bottom (2) of the ogival body (1) are thicker than in the corresponding shell for live ammunition, the actual weight (AW) of the shell for practice ammunition is smaller than the nominal weight (NW) of the corresponding shell for live ammunition and a plug (7) is soldered on the apical opening (5) for sealing the inner cavity (4) that is void, the plug (7) having a weight (PW) substantially equal to the difference between the nominal weight (NW) and the actual weight (AW).
