RIFLE CARTRIDGE FOR SMOOTHBORE WEAPONS Russian patent published in 2022 - IPC F41G3/00 

FIELD: small arms.

SUBSTANCE: invention relates to ammunition for sports and hunting smoothbore rifles, in particular to rifle cartridges for smoothbore weapons. The rifle cartridge for smoothbore weapons includes an indicator element that is installed and centrally oriented with the axis of the wad container in its inner volume and is made of a homogeneous fireproof material, to improve aerodynamic characteristics, it has the shape of a body of rotation in the form of a hollow cylinder with an upper blind end and a lower open end in the form of an expanding cone at least on part of its length, and the inner volume of the cylinder in its upper part has a weight made of soft material, and in the direction of the open end from the weight contains an indicator filler of pyrotechnic composition. At the same time, the mass of the soft weight, depending on the caliber of the fraction used, can vary and is 58-69% of the mass of the indicator element, in order to exclude uncontrolled longitudinal displacement of the longitudinal aerodynamically separable parts of the wad container assembly, they are interconnected by at least one detachable fixation element made in the form of a protrusion on one part of one aerodynamically separable parts of the wad container and a recess repeating its contours on its other part, and the upper end part of each aerodynamically separable part of the wad container contains at least one slot symmetrically located relative to the line of their connection, forming an even number of equal-sized lobes, fixation of the connected aerodynamically separable parts of the wad container with an obturating ring of powder charge communication, including an indicator element, is carried out by means of one annular protrusion and one annular recess at the place of their connection with the tension, preventing their arbitrary exit from the closed position, the wad container is made of plastic and includes a shock absorber containing at least one longitudinally oriented rib on the lower part of each of the longitudinal aerodynamically separable part of the wad container, which is symmetrically located relative to the line of their connection and forms an even number of equal internal non-through windows.

EFFECT: increase in the effectiveness of hitting targets and the expansion of technological capabilities for training shooting skills, making it possible to adjust the subsequent shot of a shotgun charge from a smoothbore rifle at the target.
