Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は命中率を向上させた散弾銃用装弾に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a shotgun cartridge with improved accuracy.
（従来技術および問題点）
散弾銃において発射された散弾集団は、拡がり（パター
ン）と長さくショットコロン長）をもって標的に向って
飛行する。(Prior Art and Problems) A group of shotguns fired from a shotgun flies toward a target with a spread (pattern) and length (shot colon length).
散弾が銃口から出たのち、空中での散弾の拡がり（パタ
ーン）は銃口から一定距離における垂直面の一定直径の
円内に入る散弾の数を全散弾の数で割って１００を乗じ
た百分率でもって、その大小を比較されている。After the shot leaves the muzzle, the spread (pattern) of the shot in the air is calculated as the percentage of the number of shot that falls within a circle of a constant diameter on the vertical plane at a certain distance from the muzzle, divided by the total number of shot, multiplied by 100. Therefore, their sizes are compared.

があることが知られている。It is said that the pattern of this shotgun has a large effect on the hit rate.If the pattern is small and the spread is large, the hit rate will improve, but on the other hand, the destructive effect on the target will decrease, so it is best suited depending on the purpose of use. It is known that there is a pattern.

る試みはなされていなかった。The pattern is controlled by the degree of choke at the shotgun's muzzle, but the controllable range is limited, so improvements have been made to the structure of the bullet. For example, in order to increase the spread of shotguns and improve their accuracy, the thickness of the side wall of the bowl-shaped body into which shotguns are loaded is reduced to 0.
It has been proposed to make the comb thinner than 5 to 0.9 mm so that it opens quickly after exiting the muzzle, or to create a weak part by making a part of the bowl-shaped body thinner or scratching it. There is. (For example, Japanese Patent Application Laid-Open No. 52-55300) On the other hand, the distance between the leading grain and the trailing grain of the flying shot group,
That is, the length of a shot colon is said to be approximately 1.5 to 3 meters within the effective firing range. Conventionally, it has been believed that a long shot colon results in poor accuracy, and no attempt has been made to systematically control and extend the length of the shot colon.

り、命中率が従来の装弾に比し著しく向上することを児
い出し本発明を完成するに到った。As a result of intensive research into methods for controlling the length of the shot colon, the inventors of the present application found that by making the length of the shot colon longer than that of conventional bullets by making use of the difference in specific gravity of shot bullets, the hit rate was lower than that of conventional bullets. The present invention has been completed by devising a remarkable improvement over the conventional method.
（問題点を解決するための手段）
すなわち本発明は、２種以上の比重の異なる散弾を装填
することを特徴とする散弾銃用装弾である。(Means for Solving the Problems) That is, the present invention is a shotgun cartridge characterized by loading two or more types of shotguns with different specific gravity.
本発明に使用する比重の異なる散弾の材質はいかなる金
１、合金を用いてもよいが通常は鉛を主体とし、これに
各種の金属を配合した合金が用いられる。鉛に配合する
金属としてはアンチモン、スズ、ビスマス等から選ばれ
た１種又は２種以上の金属である。The material of the shotguns having different specific gravity used in the present invention may be any gold alloy, but usually an alloy containing lead as a main ingredient and various metals mixed therein is used. The metal to be mixed with lead is one or more metals selected from antimony, tin, bismuth, etc.
散弾の比重に応じて鉛とこれらの金属の配合比率は適宜
選択できるが、通常鉛に対し、アンチモンその他の金属

径は、クレー射撃用あるいは猟用に通常使用されるもの
で、直径１．０〜５．０ｍの範囲のものである。The blending ratio of lead and these metals can be selected as appropriate depending on the specific gravity of the shot, but it is usually preferable to blend antimony or other metals to lead in an amount of 0.5 to 10%. If the amount of added metal is 10% by weight or more, it is not preferable because it becomes difficult to produce a true spherical shot. Further, the diameter of the shot bullet used in the present invention is one normally used for clay shooting or hunting, and is in the range of 1.0 to 5.0 m in diameter.

上の層状にＨｉ１１シてもよい。The loading structure of the present invention may be the commonly used structure illustrated in FIGS. 1 and 2, and the shot cup portion may be loaded with two or more types of shotguns having different specific gravity. The blending ratio of shotguns with different specific gravity can be selected as appropriate, but for example, in the case of two types of shotguns with different specific gravity, the weight ratio is 9515-5/
It may be blended within the range of 95%. In addition, the method of loading two or more types of shotguns with different specific gravity into the shot cup part may be as shown in Figure 1, in which they are uniformly mixed, or as shown in Figure 2, shotguns with different specific gravity can be loaded. Hi11 may be formed into two or three or more layers.

態を発生させ命中率を飛躍的に向上させるものである。(Effects of the Invention) In the shotgun ammunition loaded with two or more types of shotguns with different specific gravity according to the present invention, when fired, the flying shotguns have a different length of shot colon due to the difference in motion sides due to the difference in specific gravity. It is extended to an appropriate size and creates an effective loss condition between the flying target and the trajectory, dramatically improving the hit rate.
