  • Patent number: 10393487
    Abstract: The invention relates to a lead-free partial fragmentation bullet comprising a bullet jacket, a rear core compressed therein, and a nose core compressed in the ogive region, wherein the tip core sits on the rear core. In order that the rear core does not separate from the contacting bullet jacket upon striking a target body and to thereby guarantee a sure exit wound out of the target body, a predetermined breaking point is proposed which is arranged between the rear core and the nose core. The rear core has a molded recess on the end thereof facing the nose core, the end of the nose core facing the tail core fills in said recess, and the bullet jacket has a peripheral break away edge on the outer circumference in the region of the predetermined breaking point.

  • Patent number: 10168131
    Abstract: The invention relates to a method for producing a core (1) for a projectile (2). So that the dividing behavior of the projectile can be set in a simple manner, wherein the core is lead-free, it is proposed that one or more wires or wire sections composed of a lead-free material are compressed to form a cavity-free core (1), wherein the wires or wire sections have one or more geometrical shapes (3) in the interior or on the outside diameter and/or predetermined braking points (4) obtained during the compression are provided in the core (1).

  • Publication number: 20170248396
    Abstract: The invention relates to a Pb-free deforming/partially fragmenting projectile with a projectile body. In order to improve the killing effect of the projectile, the projectile has a fragmenting core according to the invention. The projectile body is equipped with a bore which is arranged on the longitudinal axis, extends from the tip of the projectile body, and extends into the interior, and the projectile body tip, which faces away from the projectile base has a bevel which extends from the outer circumference of the projectile body to the bore and runs at an acute angle to the longitudinal axis. The fragmenting core has a cylindrical part and a head part. The cylindrical part is arranged in the bore, and the head part protrudes out of the bore and has a support surface which is adapted to the bevel in the projectile body and together with the support surface rests on the bevel of the projectile body. The head part has a rounded tip which forms the tip of the projectile.

  • Patent number: 9500455
    Abstract: The invention relates to a projectile having a projectile base (1), an adjoining cylindrical rear region (2), and a front region (3), which is implemented as an ogive, and the projectile having one or two projectile cores (4, 5) and a projectile jacket (6). In order that when the projectile strikes a game carcass, the projectile core and the projectile jacket begin to deform simultaneously up to twice or three times the projectile diameter, it is proposed that the projectile core (4) be soldered in the cylindrical rear region (2) to the projectile jacket (6) over its entire axial length.

  • Patent number: 8578856
    Abstract: The decomposition of a projectile in a target body, particularly a hunting projectile in wild animals after penetration therein, determines the energy output of the projectile and thereby the effect of the shot. For projectiles with double cores, the properties of the ingredients used in the cores decisively affect the decomposition and particularly the deformation behavior of the cores. According to the invention, a partial decomposition projectile comprising two cores is provided with one solid core (3) made of a material suited to said projectile and the other core (4;22) is divided up into two areas (4a,4b;22a;22b), whereby one area (4a;22a) is made of ball-shaped elements made of a metal material granulate (5;23) and the second area (4b;22b) is made of a metal or ceramic powder and the ball-shaped elements or granulates (5;23) are pressed to become free of shrink holes, in order to improve decomposition behavior control.

  • Patent number: 8074574
    Abstract: A penetrator can substantially affect the fragmentation properties of a projectile. As a rule, the penetrator is enclosed by an envelope which combines the projectile core and penetrator in one unit. On hitting the target, a fragmentation of the projectile envelope must first occur which needs energy, influencing the further fragmentation of the projectile and the exit from the target. The invention thus relates to a hard-core projectile (1), with the penetrator (3) provided in a cylindrical drilling (4), in the projectile core (2), running centrally on the projectile axis (5), the length of the penetrator (3) extending over the middle (8) of the projectile, the core (2) enclosing the penetrator (3) in the ogival region (6) to the open tip (16) and the cylindrical part (7) of the core (2), serving as guide in operation, is enclosed by an envelope (9).

  • Patent number: 7735422
    Abstract: The invention relates to a ball cartridge (1) for a shotgun with an intermediate means (2) which can be built into a cartridge (20). The bullet (1) has a cylindrical free area (10) on the lower side thereof and the intermediate means (2) is embodied as a piston (21) on the end thereof facing the bullet (1) and the diameter thereof is adapted to the free area (10). In order to provide a solid link between the bullet (1) and the intermediate means (2), the bullet (1) is placed on the piston (21) or vice-versa and is pushed into the free area (10) and wedged during the piston (21) shot.

  • Patent number: 7661368
    Abstract: The aim of the invention is to gas-tightly join a jacket to a core of a hard core jacketed bullet comprising an illuminant composition in the area of the hole of the bore in the core to accommodate the illuminant composition. Said aim is achieved by pressing the material (15) of the bottom (11) of the jacket (4), which is displaced when the hole (10) is formed, against the wall of the hole by means of a reshaping process in the area of the hole (10).

  • Patent number: 7509911
    Abstract: The disintegration of a bullet in the body of a wild animal is determined by the power output of the bullet and therefore by the effect of the shot. A different type of disintegration is required for small as opposed to large animals. According to the invention, a disintegrating hunting bullet is provided in the form of an enveloped bullet, characterized in that the core (3) is made of balls (4,5) or granules made of a metal substance and the balls (4,5) or granules are pressed free from cavities in order to create set rupture points.
