Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention is explained in greater detail below with reference to FIGS. 1 and 2 which illustrate embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION

(2) FIG. 1 shows a fragmenting projectile according to the invention, which is considered to be a projectile which is a partial fragmenting projectile 1. A pressed or lathed projectile body 4 is situated in the rear of this partial fragmenting projectile 1. The base 11 of the projectile body has a funnel-shaped rear indentation 10. The projectile body 4 also has a funnel-shaped core indentation 12 on its end facing the tip of the projectile, with a fragmentable core 2 sitting on the funnel-shaped core indentation. A jacket 13 encloses the fragmentable core 2. Reference numeral 6 denotes the ogive of the projectile. According to the invention, a mark, which is visible or tangible from the outside, is provided on the ogive 6 of the projectile. This mark 9 is only indicated schematically in FIG. 1 and also in FIG. 2. This mark 9 is used to identify all of the fragmentable cores 2 of one type of projectile having the same density but differing from in the weight of the fragmentable core 2, depending on the fragmentation.

(3) All of the projectiles of one type of projectile with the same weight of the fragmentable core 2 have the same marking 9. The individual partially fragmenting projectiles 1 all have the same projectile weight, the same center of gravity and the same geometry. All partially fragmenting projectiles 1 have a fragmentable core 2 in the nose area. The term fragmentable core 2 means that it fragments into small individual parts on impact with a target. All fragmentable cores 2 of one type of projectile, that is all of the partially fragmentable projectiles 1 here, have the same density and differ from one another in the weight of the fragmentable core 2, depending on the desired fragmentation. With this partially fragmenting projectile 1, a hunter will know that they will all have the same point of impact, that is they will behave the same and the hunter can determine the degree of fragmentation in selecting the projectile. Since all fragmentation rates are characterized by the same mark 9, this choice is simplified.

(4) FIG. 2 shows another fragmenting projectile, namely a projectile of the type of the jacketed projectile 8. A solid core 3 is situated in the rear of the projectile with a fragmenting core 2 arranged thereon, sitting on the surface of the solid core 3. A jacket 13 encompasses the solid core 3 and the fragmenting core 2. A mark is applied here by a plastic tip 7 of a different color placed on the projectile.

(5) FIG. 2 shows a different graduated fragmentation 5. If a jacketed projectile, in which the weight of the fragmenting core 2 is 25%, is required, then the fragmenting core 2c is combined with the solid core 3c. Since the solid core 3c and the fragmenting core 2c have the same density, the point of impact remains constant. The plastic tip 7 is colored green.

(6) If a jacketed projectile, in which the weight of the fragmenting core 2 is 40%, is required, then the fragmenting core 2b is combined with the solid core 3b. Since the solid core 3b and the fragmenting core 2b have the same density, the point of impact remains constant. The plastic tip 7 is colored black.

(7) If a jacketed projectile, in which the weight of the fragmenting core 2 is 60%, is required, then the fragmenting core 2a is combined with a solid core 3a. Since the solid core 3a and the fragmenting core 2a have the same density, the point of impact remains constant. The plastic tip 7 is colored red.

(8) The invention thus includes a partially fragmenting projectile 1. The projectile body 4 may be a pressed or lathed projectile body having a fragmentable front core 2. The invention also includes a jacketed projectile 8 having two cores, one solid core 3 in the rear area and a fragmentable core 2 in the front area of the projectile. With both types of projectiles, the same or different materials with the same density may be used for the projectile cores. The different graduated fragmentation 5 is achieved by weight gradations in the fragmentable core 2 at the same projectile weight, center of gravity and geometry. This results in a graduated fragmentation with the same point of impact. The individual types of projectiles can be identified by a colored identification in the region of the ogive 6 of the projectile (FIG. 1) or with attached plastic tips 7 of the different colors (FIG. 2). For night-time use, the individual types of projectiles can be provided with marks in the region of the ogive 6 of the projectile, depending on the fragmentation of the projectile, such that these marks consist of recesses or elevations that can be perceived by the human hand.

(9) Description of the Projectile Cores

(10) The material of the cores may consist of lead-free materials, which can be soldered or pressed up to six tons without shrinkage cavities.

(11) In the case of a projectile having a pressed projectile body 4, the fragmenting core 2 in the front region of the projectile must have the same specific gravity as the pressed projectile body 4.

(12) For the jacketed projectile having two cores, the rear solid core 3 may consist of different materials with the same density as the front fragmentable core 2 but the same material and the same specific gravity are advantageous.

(13) Mechanism of Action of the Projectile

(14) Fragmentation of a projectile in the target body, in particular a hunting projectile in the body of a wild animal after penetration into same, determines the energy released by the projectile and thus the effect of the shot. In the case of a weak animal, for example, a different fragmentation may be necessary than in the case of a strong animal. Both a partially jacketed projectile with a pressed base body and a jacketed projectile whose projectile core or cores are made up of a solid core and a fragmentable core may be used.

(15) The front fragmentable projectile core held by the pressed base body or projectile jacket fragments with the projectile jacket as far as the solid core on impact in the target body. The percentage amount of the fragmentable core of the total weight of the projectile determines the energy released in the target body with the same point of impact over the total distance of the shot despite different fragmentation ratios from one shot to the next. The hunter here has the opportunity of selecting the best fragmentation ratio for the animal to be shot and the distance of the shot.
