The present invention relates generally to a projectile, and more particularly to a projectile that includes stabilization fins and for the components for loading the projectile into a cartridge.
Standard bullets, projectiles or rounds are cylindrical, pointed objects that are fired from a barrel with rifling therein. The rifling in the bore instills spin and, therefore, stability in the projectile as it travels to its target. As the projectile travels down the barrel a high amount of chamber pressure and friction causes portions of the projectile to be cold formed. This causes the barrel to heat up. The present invention helps solve this problem.

In a preferred embodiment, the central opening of the preload die is tapered. Preferably, the plunger die includes a pusher portion extending outwardly from a first end of the main body portion. In a preferred embodiment, the system or kit includes at least one projectile assembly that includes a projectile that includes a nose portion, a middle portion, a rear portion, and a plurality of fins extending outwardly from the rear portion, a jacket that surrounds at least a portion of the projectile and includes an exterior surface and an interior surface. The jacket includes a front cone. A plurality of annular grooves are defined in the exterior surface. The front cone and the nose portion of the projectile are positioned outside of a casing into which the remainder of the covered projectile are inserted. The system or kit can also include a barrel that includes threads thereon.
In accordance with another aspect of the present invention there is provided a projectile that includes a front portion that includes a tip, a middle portion that includes a plurality of annular grooves defined therein, and a rear portion that includes a tail and a plurality of fins extending outwardly therefrom. Preferably, the middle portion has a greater diameter than the nose portion and the rear portion. Preferably, the rear portion includes a waist portion and a cone portion and the diameter of cone portion increases between the waist portion and the tail.
The invention may be more readily understood by referring to the accompanying drawings in which:
Like numerals refer to like parts throughout the several views of the drawings.
The following description and drawings are illustrative and are not to be construed as limiting. Numerous specific details are described to provide a thorough understanding of the disclosure. However, in certain instances, well-known or conventional details are not described in order to avoid obscuring the description. References to one or an embodiment in the present disclosure can be, but not necessarily are references to the same embodiment; and, such references mean at least one of the embodiments.
Reference in this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the-disclosure. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Moreover, various features are described which may be exhibited by some embodiments and not by others. Similarly, various requirements are described which may be requirements for some embodiments but not other embodiments.
The terms used in this specification generally have their ordinary meanings in the art, within the context of the disclosure, and in the specific context where each term is used. Certain terms that are used to describe the disclosure are discussed below, or elsewhere in the specification, to provide additional guidance to the practitioner regarding the description of the disclosure. For convenience, certain terms may be highlighted, for example using italics and/or quotation marks: The use of highlighting has no influence on the scope and meaning of a term; the scope and meaning of a term is the same, in the same context, whether or not it is highlighted.
It will be appreciated that the same thing can be said in more than one way.
Consequently, alternative language and synonyms may be used for any one or more of the terms discussed herein. No special significance is to be placed upon whether or not a term is elaborated or discussed herein. Synonyms for certain terms are provided. A recital of one or more synonyms does not exclude the use of other synonyms. The use of examples anywhere in this specification including examples of any terms discussed herein is illustrative only, and is not intended to further limit the scope and meaning of the disclosure or of any exemplified term. Likewise, the disclosure is not limited to various embodiments given in this specification.
Without intent to further limit the scope of the disclosure, examples of instruments, apparatus, methods and their related results according to the embodiments of the present disclosure are given below. Note that titles or subtitles may be used in the examples for convenience of a reader, which in no way should limit the scope of the disclosure. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. In the case of conflict, the present document, including definitions, will control.
It will be appreciated that terms such as “front,” “back,” “top,” “bottom,” “side,” “short,” “long,” “up,” “down,” “aft,” “forward,” “inboard,” “outboard” and “below” used herein are merely for ease of description and refer to the orientation of the components as shown in the figures. It should be understood that any orientation of the components described herein is within the scope of the present invention.
Referring now to the drawings, which are for purposes of illustrating the present invention and not for purposes of limiting the same, the figures show various embodiments of bullets or projectiles.
As is shown in
It will be appreciated that the geometry and shapes of both the projectile and the jacket may change based on calibers and projectile weights. Fin shape and mass can be modified to move the CG (center of gravity) and increase or decrease rotation and stability in projectile flight. Generally, the system allows the overall shape of the projectile envelope flexibility not achievable in traditional projectiles.
The jacket 34 also includes projectile recess(es) 39 on an inside surface thereof that generally conform to the outer surface of the projectile 32. As shown in

The barrel 106 can be sold as part of the kit discussed above. The kit can include the barrel 106, a plurality of covered projectiles 30 and/or projectile assemblies 104 and the assembly components, such as the casing die 60, plunger die 62, receiver die 64 and preload die 66.
It will be appreciated that the covered projectile 30 provides lower friction and drag compared to the prior art, which results in lowered friction heating and reduced barrel wear. The fins provide stabilization in flight. A rudder may be included in the fin to augment rotation in flight. The body of the projectile is formed to lower drag in flight and increase airflow in the fin area. As a result, the inventor has found that speed is increased and velocity degradation is reduced. In an exemplary embodiment, the projectile is made of copper, however, any metal or material is within the scope of the invention.
