Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harmless ammunition for hunting large wild animals using a shotgun.

[0002]

2. Description of the Related Art Conventionally, when hunting a large wild beast such as a deer using a shotgun, a single bullet made of lead with a diagonal notch in the outer peripheral surface in the shape of a bell, or 6 to 9 lead bullets is used. Ammunition loaded with steel bullets has been used. Because lead bullets are soft and have a high specific gravity, they do not hurt the barrel even if they move inside the barrel at a speed higher than the speed of sound, and they can achieve the expected accuracy and power even with a shotgun with a smooth inner surface It was an ideal bullet in terms of performance. In recent years, however, waterbirds have swallowed normal lead shots submerged in the water with sand, resulting in poisoning. It has been confirmed that birds of prey such as steller's sea eagle and white-tailed eagle, which are designated as rare animals on the basis of food, eat poisonous pieces of lead scattered in pieces of meat and die from poisoning.

[0003] On the other hand, it is also an important issue to control birds and beasts for maintaining agriculture and forestry, and to adjust the population of wildlife for preserving the natural environment. ing. Therefore, instead of a lead bullet as shown in FIG. 5, a copper bullet 19 is used, and a sabo 18 which covers the bottom surface from the side face of the bullet and has a plurality of slits 21 of a uniform depth and width in front of the side face portion. Slug bullets combined with are known. Reference numeral 20 denotes a slit also provided at the tip of the single bullet. In the case of a shot using this slug ammunition, a shotgun with a rifle on the inner surface has a good hit accuracy, but a shotgun with a smooth inner surface without a rifle has a poor hit accuracy, sometimes a gun Was sometimes damaged. Therefore, when a harmless material is used, there is a problem that any shotgun cannot be applied.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to use a slug bullet (single bullet) that does not destroy nature,
Moreover, even when applied to a shotgun with a smooth inner surface, it provides a harmless shot that can hunt large wild beasts such as deers because it does not damage the gun, has high accuracy and is powerful. is there.

[0005]

Means for Solving the Problems The present inventors have made intensive studies to achieve the above object, and as a result, the conventional problems have been solved by using a single bullet made of non-toxic material in combination with a specific sabo. After confirming that the present invention can be performed, the present invention has been completed. The present invention provides a single shell, sabo,
A wad, a propellant, and a primer are sequentially arranged, the single ammunition is made of a non-toxic material, and the sabo covers the bottom surface from the side surface of the single ammunition and divides into a plurality in the circumferential direction from the outer side surface to the bottom surface. This is a harmless shot for a shotgun, characterized by having a slit that gradually becomes deeper.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a partially broken sectional view and a bottom view showing an example of a harmless shot for a shotgun of the present invention. In the harmless shot for a shotgun of the present invention, a warhead 2, a specific sabo 3, a sabo support 4, a cushion wad 5, a propellant presser 6, a propellant 7, and a primer 8 are sequentially arranged in a cartridge case 1. In the case of the present embodiment, the plastic case 1 is made of a plastic which has been used in a conventional case and has a proven track record in terms of manufacturability and the like. The warhead 2 is a single bullet, and in this example, a single bullet made entirely of copper is used as a non-toxic material. Non-toxic materials for the warhead 2 include tin, soft iron,
Bismuth etc. can be adopted, but manufacturability / processability, economic efficiency,
From the viewpoint of specific gravity or the like that affects performance, copper alone or a combination of copper and tin is preferable.

The size of a single bullet can be appropriately selected depending on the type of wild animal, the caliber of a shotgun, and the like. Further, as the shape, a warhead shape as shown in FIGS. 1, 3 and 4 is usually adopted. If necessary, a slit may be provided in the rounded portion of the tip of the warhead so that the tip of the warhead is opened outward by the impact at the time of impact, and the cross-sectional area may be increased to increase the damage to the prey. In the case of a warhead combining copper and tin, the same effect can be obtained even if there is no slit in the warhead, since the tin portion is disengaged when landing and the side portion of the copper covering the tin portion opens outward. .

The sabo 3 used in the present invention is characterized by the form of the slit and the combination of the warhead 2. FIG. 2 is a longitudinal sectional view and a bottom view of the sabo used in FIG. The sabo 3 has a U-shaped cross section as shown in FIG. 2, and a single bullet 2 (in this case, an all-copper warhead) is closely inserted into the inner space 10 as shown in FIG. Therefore, the side surface 11 and the bottom surface 12 of the single bullet are covered by the sabo 3. In this way, the barrel is protected. On the other hand, the outer side surface 16 of the sabot 3 must have the slit 9 toward the bottom surface 17. A plurality of slits 9 are provided in the circumferential direction of the sabo 3 in a plurality of equal parts. In the figure, four slits 9 are provided at intervals of 90 degrees in the circumferential direction. The number of slits 9 is usually 3
More than one book. Also, this slit needs to be gradually deeper toward the bottom. Because the warhead 2 and the sabo 3 fired from the muzzle fly toward the target, the action of the slit enables stable flight. This is an operation equivalent to a bow and arrow. For this reason, a rifle is not provided on the inner surface of the barrel, and even a smooth shotgun has a feature that the hit accuracy is high. When impacted, the sabo is broken and only the single ammunition hits the target straight, thus increasing its penetration.

If there is no such vertical slit in the sabo, the warhead will roll over after leaving the muzzle, and the posture will not be stable, and the accuracy of hit will be reduced, and the penetration force will also be reduced. As shown in FIG. 5, a conventionally known slug bullet has a sabo slit direction opposite to that of the present invention, is provided forward, and has a uniform depth. As a result, Sabo opens and separates from the ammunition, and only the ammunition flies toward the target. Therefore, when used on a shotgun with no rifle applied to its inner surface, flight stability is deteriorated, so that the accuracy of hitting is reduced. The material of the sabo used in the present invention is a material having a strength capable of withstanding a large shock and friction applied at the time of launch, and generally,
An elastic thermoplastic resin (plastics) is used. For example, a thermoplastic resin such as polyethylene or polypropylene is used. Depending on the required elasticity,
For example, high-density polyethylene and low-density polyethylene may be blended in an appropriate ratio. Sabo having such elasticity does not damage the shotgun.

The example of FIG. 4 is a longitudinal sectional view of a warhead 13 having a tip of tin 14 and a remainder of copper 15 as a non-toxic material. When different metals are used in combination as non-toxic materials as in this example, the specific gravity of each metal is different, so the shape of the combination should be considered from the viewpoint of flight stability. In FIG. 1, conventionally known cushion wads 5, propellants 7, and primers 8 can be used.

[0011]

The harmless bullet of the present invention can destroy nature by using a single bullet made of non-toxic material and a specific sabo, especially a sabo having a characteristic in the direction and depth of a slit. It is a harmless shot suitable for hunting large wild beasts such as deer, because it has no damage to the gun even if it is applied to a shotgun with a smooth barrel inner surface, and it has high accuracy and power. .

[0012]

EXAMPLES The present invention will be described more specifically below with reference to the relationship between examples and comparative examples. Example 1 Ten bullets shown in FIG. 1 were produced using an all-copper warhead as a single bullet as shown in FIG. 3 and a sabo shown in FIG. The material of the sabo is polyethylene. In addition, the slit provided in the sabo is about half the bottom side of the sabo, from the outer side surface to the bottom, the width is from 0.8 mm to 1.0 mm vertically, the depth is 0 mm in the front and the depth is toward the rear. It is gradually deeper, with the last end being 2 millimeters, four equally spaced in the circumferential direction of the sabo. 5 shots of this ammunition were fired with a fixed-speed pressure measuring gun of caliber # 12 (a smooth shotgun with no rifle on its inner surface) aimed at a target placed at a distance of 50 meters. The distance (grouping) from the center of the two most distant holes to the center was 65 mm. This can be said to be almost the same performance as a lead single bullet. Inspection of the mark on the target confirmed that all the bullets had penetrated almost straight. The remaining five shells were then fired on the oil clay at a distance of 37 meters using the same gun. Each sabot was disengaged from the warhead upon impact, leaving only the warhead rushing into the clay. The landing section had an average inlet diameter of about 45 millimeters and an average depth of 280 millimeters.

Example 2 As a single bullet, a copper bullet with tin embedded at the tip end as shown in FIG. 4 was used instead of an all-copper warhead. The shape of the portion in which tin is embedded is about 10 mm in diameter and about 10 mm in depth, coaxial with the bullet. The same sabo as in Example 1 was used except that the number of sabo slits was equally divided in the circumferential direction. Using this bullet, the same grouping as in Example 1 and the shape of the landed portion on the oil clay were obtained.
As a result, the grouping was 100 millimeters. Inspection of the mark on the target revealed that all the bullets had penetrated almost straight. The shape of the landing portion on the oil clay had an average inlet diameter of about 55 mm and an average depth of 225 mm. The recovered warhead had a petal-shaped tip, and the tin portion was deformed and advanced further.

Comparative Example 1 A test was conducted in the same manner as in Example 1 except that a known copper single bullet was used and a known sabo shown in FIG. 5 was used. As a result, Sabo was falling a few meters in front of the gun. The grouping was 240 millimeters. Also, when examining the trace of penetration into the target, the bullet was landed diagonally. The shape of the landing portion on the oil clay had an average entrance diameter of about 90 mm and an average depth of 200 mm.

From the results of the above Examples and Comparative Examples, the harmless shot of the present invention has better hit accuracy and power than conventional shots even when using a smooth shotgun without a rifle on its inner surface. It turns out to be big.
