摘要： A rifle or handgun bullet having a base and a leading end of ogival shape extending for a portion of its length is divided into a plurality of sections by parting lines extending radially from the central axis and terminating a short distance from the outer wall, whereby the sections are joined by relatively thin webs at their outer edges. The parting lines extend longitudinally from the leading end through at least the ogival portion to as much as 90% of the length of the bullet. Upon impact with a lubricious target the sections separate from one another and from the base, i.e., the portion into which the parting lines do not extend. The bullet is fabricated in a two-stage operation, first forcing a punch longitudinally into a cylindrical slug of malleable metal contained within a die, and then compressing the slug radially inwardly to force essentially all air from the spaces formed by the punch, thereby and forming the ogival leading end.

摘要： A fully plated hollow-point bullet and a method of manufacturing the bullet wherein a malleable metal precursor core having a central cavity and a surrounding wall is divided into a series of petals, each petal being separated from one another by an air space, and all interior and exterior surfaces of the precursor core, including individual petals, are thereafter electroplated with a second metal and final formed in a hollow-point pointing die, ultimately producing a more robust bullet and one that expands easier and faster on impact than plated bullets of conventional manufacture.

摘要： A three component bullet with an improved core retention feature and a method of manufacturing the bullet is described including a cylindrical jacket having an open end and a closed end containing a malleable metal core which is forced into a forming die having a bottleneck shaped interior resulting in a bottleneck shaped pre-form wherein the outside diameter of the open-ended forward portion of the jacket is smaller than the outside diameter of its closed rearward portion. The open end of the pre-form may be dropped through or forced through a malleable locking band of appropriate height, diameter and wall thickness. A relatively tight-fitting punch enters the open end of the pre-form generating sufficient axial force against the face of the metal core to radially swell the core and subsequently portions of the jacket fore and aft of the locking band, thereby securing the locking band in place while at the same time producing an inwardly-extending annular band of jacket material which embeds itself into the core material with the result that the core is permanently locked inside the jacket.

摘要： A bullet comprised of a jacket of malleable metal having a closed nose portion and a rear end portion defined by a cylindrical wall, the closed nose portion having wall-weakening areas encapsulating a forward core made of a deformable material which promptly deforms, collapses axially, and expands radially to a substantial extent along with the weakened wall areas, when the bullet strikes a target. The nose portion has wall-weakened areas which are ruptured by the core material to produce a collapsing and radially expanding action. These weakened wall areas are in the form of longitudinally extending, deep, internal or external, circumferentially spaced grooves with underlying web areas which are ruptured by the core material, to produce the collapsing and expanding action. This core is preferably made of rubber, urethane, silicone, or one of a substantial number of plastics, each of which has a hardness within a range of Shore A 20 to Rockwell 122. A second core, made primarily of metal or plastic, and preferably softer than the metal of the jacket, is seated, under pressure, behind the nose core and within the rear end portion of the jacket. The advantages of the bullet result from the fact that it collapses axially and expands widely and quickly, upon striking the target, and yet penetrates an adequate distance, without losing an appreciable amount of weight, and without passing through the entire body of the target, to thereby provide an adequate penetration, optimum expansion bullet.
摘要翻译：一种由具有闭合鼻部的可延展金属夹套和由圆柱形壁限定的后端部分组成的子弹，封闭的鼻部具有封闭由可变形材料制成的前芯的壁弱化区域，该可变形材料迅速变形，轴向塌缩，并且当子弹撞击目标时，沿着弱化的壁区域径向膨胀到大致程度。鼻部具有由芯材料破裂以产生塌陷和径向扩张作用的壁弱化区域。这些弱化的壁区域是纵向延伸的，深的，内部的或外部的周向隔开的凹槽，其下面的腹板区域被芯材料破裂，以产生塌缩和膨胀作用。该芯优选由橡胶，聚氨酯，硅树脂或大量塑料中的一种制成，其中每一种具有硬度在肖氏A20至洛氏520的范围内。主要由金属或塑料制成的第二芯和优选地比夹套的金属更软，在压力下安置在鼻芯之后和护套的后端部分中。子弹的优点是由于其塌陷并且在撞击目标时广泛而快速地膨胀，并且穿透足够的距离而不会损失可观的重量并且不通过目标的整个身体的事实，从而提供足够的穿透力，最佳的膨胀子弹。

摘要： A bullet comprised of a jacket of malleable metal having a closed nose portion and a rear end portion defined by a cylindrical wall, the closed nose portion having wall-weakening areas encapsulating a forward core made of a deformable material which promptly deforms, collapses axially, and expands radially to a substantial extent along with the weakened wall areas, when the bullet strikes a target. The wall weakened areas of the nose portion are ruptured by the core material to produce a collapsing and readily expanding action. These weakened wall areas are in the form of longitudinally extending, deep, internal or external, circumferentially spaced grooves with underlying web areas which are ruptured by the core material, to produce the collapsing and expanding action. This core is preferably made mainly of rubber, urethane, silicone, or one of a substantial number of plastics, such as fluorocarbons, polycarbonates, polypropylenes, polystyrenes, polyethylenes, PVC™, silicone rubber, Nylon™, and vinyl acetate, each of which has a hardness within a range of Shore A-20 to Rockwell R-122. A second core, made mainly of metal such as tungsten, lead, zinc, copper, tin, iron or alloys thereof or hard plastic, is seated, under pressure, behind the nose core and within the rear end portion of the jacket. The advantages of the bullet result from the fact that it collapses axially and expands widely and quickly, upon striking a target, and yet penetrates an adequate distance, without losing an appreciable amount of weight, and without passing through the entire body of the target, to thereby provide an adequate penetration, optimum expansion bullet.

摘要： A bullet comprised of a jacket of malleable metal having a closed nose portion encapsulating a forward core made of rubber, the nose portion having circumferentially spaced, axially extending deep scores in its nose-defining walls, and a rear core within the jacket made of a malleable metal preferably softer than that of the jacket and hard-seated against the rear of the rubber core to bring pressure against the interior surface of the meplat and the interior surface of the nose-defining walls of the nose portion, whereby upon the bullet striking and penetrating a target, the scores will rupture and the nose-defining walls of the nose portion will collapse axially and open, and together with the rubber core, will expand substantially in a radial direction to thereby provide an adequate penetration, optimum expansion bullet.
