Partial fragmentation and deformation bullets having an identical point of impact
First Claim
1. A method for fabricating jacketless cored bullets, including both a partly fragmenting bullet and a deformable bullet, comprising:
- fabricating a deformable bullet having a bullet tip and a bullet tail, and having an enclosed cavity within the bullet tip, the enclosed cavity being closed by a cap, the deformable bullet comprising a base alloy of copper and zinc; and
fabricating a partly fragmenting bullet having a bullet tip and a bullet tail, and having an enclosed cavity within the bullet tip, the enclosed cavity being closed by a cap, the partly fragmenting bullet comprising a base alloy of copper and zinc;
wherein the partly fragmenting bullet is fabricated with an impact point position, a caliber, an external volume, a mass, and a center of gravity substantially identical to that with which the defomiable bullet is fabricated, but wherein the enclosed cavity of the partly fragmenting bullet is enlarged relative to the deformable bullet by an additional portion and wherein a mass loss caused by enlargement of the enclosed cavity of the partly fragmenting bullet is compensated by changing relative proportions of copper and zinc in the base alloy and/or by adding at least one element positively influencing fragmentation at the cost of the copper and zinc of the base alloy.

Abstract
Especially in hunting, the choice of bullets has to be such that it is in keeping with the wild animals to be hunted. According to the desired effect on the target, deformation bullets or partial fragmentation bullets are used. Since both types of bullets are different, the position of the point of impact from the same weapon is different. According to the type of bullet used, the weapon must be oriented differently in relation to the target. This can be obstructive and if insufficient attention is paid, can result in misses. According to the invention, a shell-less cored steel bullet is used as a deformation bullet (1) or partial fragmentation bullet (2), having an identical caliber and a closed cavity (4) in the tip (3) of said bullet In order to achieve the same point of impact of said bullets (1,2) on the target, while maintaining the effect of the respectively selected bullet during the same handling of the weapon, during the same setting of the target in an identical position, the external volume, centre of gravity, mass and base copper-tin alloy are identical and the cavity (E) in the tip (3) of the bullet, consisting of a combination of cylindrical and conical sections (10, 12, 13; 20), in addition to the composition of the bullet material, are adapted to the effect of said bullet.

7. A set of jacketless cored bullets, including both a partly fragmenting bullet and a deformable bullet, comprising:
-
a deformable bullet having a bullet tip and a bullet tail, and having an enclosed cavity within the bullet tip, the enclosed cavity being closed by a cap, the deformable bullet comprising a base alloy of copper and zinc; and a partly fragmenting bullet having a bullet tip and a bullet tail, and having an enclosed cavity within the bullet tip, the enclosed cavity being closed by a cap, the partly fragmenting bullet comprising a base alloy of copper and zinc; wherein the partly fragmenting bullet has an impact point position, a caliber, an external volume, a mass, and a center of gravity substantially identical to that of the deformable bullet, but wherein the enclosed cavity of the partly fragmenting bullet is larger relative to the enclosed cavity of the deformable bullet by an additional portion and wherein a mass loss caused by the larger enclosed cavity of the partly fragmenting bullet is compensated by a change in relative proportions of copper and zinc In the base alloy and/or by an addition of at least one element positively influencing fragmentation at the cost of the copper and zinc of the base alloy. - View Dependent Claims (8, 9, 10, 11, 12)
