Description
Die Läufe der Jagddoppelflinten weisen jetzt eine Chokebohrung (Kaliberverengung an der Mündung) in stärkerer oder schwächerer Ausführung auf. Die Erfindung ist ein Ersatz dieser Chokebohrung durch Anordnung eines Dralls von 3 bis 5 cm Länge in der Mündung des Flintenlaufs i mit drei 8 mm breiten Zügen 2 und einer Zugtiefe von o,25 mm bei einer Drallänge von 5o bis 6o cm. Diese Anordnung hat den Zweck, das Flintenlaufgeschoß zur Rotation zu bringen und .einen sicheren Abgang des Geschosses an der Mündung zu erzielen und eine erhöhte Präzision zu erreichen.The barrels of the hunting double shotguns now have a choke hole (caliber narrowing at the mouth) in a stronger or weaker version. The invention is a replacement of this choke hole by arranging a twist of 3 to 5 cm in length in the muzzle of the shotgun barrel i with three 8 mm wide slides 2 and one draw depth of 0.25 mm with a twist length of 5o to 6o cm. The purpose of this arrangement is to make the shotgun barrel rotate and. a safe exit of the bullet to achieve at the mouth and to achieve increased precision.
Außerdem wird eine Verbesserung der Schrotschußleistung und gleichmäßigere Verteilung der Schrote hierdurch angestrebt. Die besonders breiten, flachen Züge und Felder haben keine scharfen Kanten und wirken sich deshalb günstig für den Schrotschuß aus. Die Zeichnung I zeigt den Laufquerschnitt mit dem Dreifelderzug. Die Draufsicht zeigt die Mündung mit diesen Zügen und Feldern gestrichelt.It also improves the shotgun performance and becomes more uniform This is aimed at distributing the shot. The particularly wide, flat trains and fields have no sharp edges and are therefore favorable for the shotgun the end. Drawing I shows the cross-section of the barrel with the three-field train. The top view shows the mouth with these trains and fields in dashed lines.
