Combined Shot-Wadcutter Ammunition and Methods for Manufacturing the Same

Abstract

A small arms cartridge load that fires bird shot and a full wadcutter bullet. The cartridge is loaded with both a wadcutter and shot. A cup crimped to the casing is used to secure the contents inside the casing. No plastic capsule is needed to secure the shot in place. Removing the plastic capsule prevents the shot from taking the rifling and thus keeping the pattern tighter to extend the effective distance of the shot. The wadcutter can be hard cast to provide greater penetrating force. The load can be effective in deterring varmints or for defensive purposes.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present embodiments of the present invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present invention, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed descriptions of the embodiments of the apparatus, as represented in FIGS. 1 and 2 are not intended to limit the scope of the invention, as claimed, but are merely representative of present embodiments of the invention.

[0014] In general, the figures disclose an invention that provides ammunition having a both a solid projectile and dispersed projectiles

[0015] In the following description, numerous references will be made to ammunition. However, it should be understood that one of ordinary skill in the art and in possession of this disclosure, would readily understand how the present invention and existing firearm cartridge structures and pneumatic cartridge structures can be incorporated.

[0016] Detailed references will now be made to the preferred embodiments of the present invention, examples of which are illustrated in FIG. 1 which illustrates an exploded view of the ammunition in accordance with one or more embodiments of the invention.

[0017] In some embodiments a cartridge 100 comprising a casing having a mouth 104 formed on a distal edge 106 of the casing. In some embodiments the mouth 104 comprises and distal end of the casing opposite the case head 118. In some embodiments the casing comprises a cavity. In some embodiments the cavity is configured to receive content 108.

[0018] In some embodiments a cup 110 is used to enclose the cavity and secure the content 108 inside the cartridge. In some embodiments the cup 110 is a think metal disc that is formed into a cup-shape with an outer diameter that is approximately the inner diameter of the casing mouth. In some embodiments the cup 110 is inserted into the cartridge mouth 104. In some embodiments the cup 110 comprises a dome, or a flattened dome. In some embodiments the cup 110 comprises an edge. In some embodiments the cup 110 is placed in the mouth 104 with the dome protruding toward content 108, leaving the cupped side of the cup 110 facing out. In some embodiments the cup 110 rests on the content 108 when placed in the mouth 104. In some embodiments the cup 110 flange is oriented upward and is aligned flush with the distal edge 106 of the case mouth 104 and allows for a very tight weld with the crimp at the case mouth 104.

[0019] In some embodiments the casing is metal. In some embodiments the cup 110 is metal. In some embodiments the cup 110 and the casing are crimped to secure the cup 110 to the mouth 104 and retain the content 108 inside the cartridge is disclosed. In some embodiments the cup 110 is inserted into the casing using a rod, and the crimping occurs when the cup 110 is supported by the rod. In some embodiments the cup 110 is placed in the casing mouth 104 and a second tooling is used to crimp the cup 110 and casing. The crimped casing 102cup 110 is an improvement over existing techniques, such as CCI's pest control shot shell which employs a capsule to secure the content 108 in the casing. A capsule engages rifling which spreads the shot pattern and reduces the distance over which the shot is effective, meaning maintains sufficient velocity to impact a target. In contrast, the cup 110 does not encapsulate the shot 114, thus avoiding increased engagement between the shot 114 and rifling and improving the effective distance of the shot 114. In some embodiments the cup 110 is inserted into the mouth 104 of the cartridge to create a lacuna 115 below the mouth 104 of the cartridge. In some embodiments crimping the cup 110 to the casing secures the content 108 in the casing during the violent motion that occurs while the gun is firing.

[0020] In some embodiments the cup 110 is secured to the casing using adhesive. In some embodiments the cup 110 is secured to the casing with friction.

[0021] In some embodiments the casing contents comprise a gun powder 112. In some embodiments the casing contents comprise a plurality of shot 114. In some embodiments the casing contents comprise a wadcutter 116. In some embodiments the wad cutter is a full caliber. In some embodiments the wadcutter is smaller than a full caliber. In some embodiments the wadcutter is greater than a full caliber. In some embodiments the wadcutter 116 is hard cast to prevent deformation or mushrooming upon penetration. In some embodiments the wadcutter 116 is configured engage the rifling to improve the stability of the trajectory of the wadcutter 116 along with improving its accuracy.

[0022] In some embodiments the casing houses the combination of gun powder 112, shot 114, and wadcutter 116. In some embodiments the contents 108 of the casing are loaded into the casing through the mouth 104. In some embodiments the content 108 inside the cavity of the casing fills the cavity to near the distal rim of the mouth 104. In some embodiments the content 108 is contained inside the casing below the mouth 104 the distance of the cup depth.

[0023] In some embodiments at least a portion of the content 108 is in contact with the casing because there is no encapsulation. In some embodiments the cartridge comprises the casing and the cup 110 without additional encapsulation. In some embodiments the contents are enclosed by the casing and the cup 110 only. In some embodiments the shot 114 is 000 buckshot. In some embodiments the shot 112 is 00 buckshot.

[0024] In some embodiments the a cartridge comprises a casing having a case head 118 and a mouth 104, a quantity of gun powder 112 deposited proximate the case head 118, a hardcast wadcutter 116 deposited adjacent the quantity of gun powder 112, a plurality of shot 114 deposited adjacent the hardcast wadcutter 116, and a metallic cup 110 having an edge wherein the cup 110 is set inside the casing and against the plurality of shot 114 so that the edge of the cup 110 is approximately level with the mouth 104 of the casing and wherein the cup 110 and the casing mouth 104 are crimped to secure the cup 110 to the casing and wherein the plurality of shot 114 is below the mouth 104 so as to be disposed inside the casing. In some embodiments the case head 118 comprises a rim fire primer. In some embodiments the case head 118 comprises a center fire.

[0025] Referring now to FIG. 3, which illustrates an embodiment of a method of securing shot and a wadcutter 116 inside a casing, the method comprising filling a casing having a mouth with a content comprising a quantity of gunpowder, a plurality of shot and a wadcutter 302, placing a cup inside the mouth so as to contain the contents of the casing are recessed below the mouth of the casing 304, and crimping together the cup and the mouth of the casing to couple the cup to the casing and securing the quantity of gunpowder, the plurality of shot and the wadcutter inside the casing 306. In some embodiments method further comprising filling the casing with the quantity of gunpowder, the plurality of shot and the wadcutter through the mouth 308.

[0026] In closing, it is to be understood that the embodiments of the disclosure disclosed herein are illustrative of the principles of the present disclosure. Other modifications that may be employed are within the scope of the disclosure. Thus, by way of example, but not of limitation, alternative configurations of the present disclosure may be utilized in accordance with the teachings herein. Accordingly, the present disclosure is not limited to that precisely as shown and described.
