Abstract (en)

The invention involves a rigid polyethylene ring, cylindrical (3a) or conical (3b) in cross-section, with fixed outer diameter according to its respective caliber of application, on which the bottom end rests on the inner bottom (2a,2b), of the plastic or paper bullet casing (1) and enclosing within it the necessary amount of gunpowder (4b, 4c), with its upper end exceeding one half (0.5) millimeter in height over the gunpowder and the resting wad , i.e. plastic concentrator (6a) or wool wad (6b), creating between gunpowder (4b,4c) and wad, discoid space (5), about half (0.5) millimeter. Thus, the Ring (3a,3b), completely absorbs the strong pressures exerted by the weight of the shot shells (7) and by the asteroid closure (8) of the cartridge and allows no pressure to be applied to the gunpowder (4b,4c), thereby completely equating the same cartridges of the same batch , in terms of pressures generated by its burning, and ensuring the required corresponding stability between shots of the shotgun.
