Abstract: A bullet is manufactured by providing a slug of metal having an end face and applying an axial force against the end face of sufficient magnitude to form an axially outwardly opening first cavity. Thereafter a second force is applied against the first cavity to reform the first cavity into a second cavity having a peripheral edge of a generally scalloped configuration and an interior surface defining tears of alternating triangular flat faces set-off by edges converging toward a blind end of the cavity. The end portion is then contoured into a generally convex curvature which constricts the scalloped peripheral edge and transforms the triangular faces into radially inwardly directed ribs and alternating lines of weakness which, upon bullet impact, control radial expansion and axial tearing of petals formed during impact which creates maximum hydraulic shock in the absence of fragmentation which in turn ensures humane killing of game.

Abstract: A projectile-forming explosive charge-insert of intensified penetrating power into a target, wherein a mass or weight component is centrally positioned in the insert, and the weight member possesses at least one shank projecting into the explosive charge. The weight member or mass serves as a stabilizer during the deformation of the insert into a projectile. The deformation procedure is favorably influenced by the weight member; in effect, during the collaboration of the insert in the region of the head, the mass or weight member acts in a damping or attenuating manner. Governing for the attenuating property of the weight member is, accordingly, its length towards the explosive and its attenuating capacity specific to its material.

Abstract: A high penetration bullet is provided which is made of lead and is of one piece construction. The nose of the bullet includes an outer nose portion, including an external, shaped (e.g., ogive) surface which gives the tip of the nose of the bullet its basic shape, and an inner nose portion including an internal, shaped (e.g., ogive) surface. The outer and inner nose portions are separated by a thin layer of a lubricant which is trapped between adjacent surfaces of the two nose portions when the stem or neck of an intermediate stage bullet element is peened over the inner nose portion during the formation of the outer nose portion. As a consequence of this construction, upon impact of the bullet with a target, the outer nose portion will decelerate and be impacted from behind by the trailing mass of the remainder of the bullet.

Abstract: A shotgun shell loaded with steel shot utilizes a number of magnetized steel pellets intermixed in the load in order to form clusters of pellets as the load is discharged from the shell to thereby improve the shot pattern of relatively lightweight steel shot, steel being less dense than lead. The magnetized steel pellets may be either randomly mixed throughout the load or concentrated in one or more areas of the load. If concentrated in the middle of the load, a much larger cluster of shot is believed to be expelled from the gun barrel upon discharge of the shell. A Teflon.TM. or the like coating may be applied to the steel shot, or lubricants included in the load in order to lubricate the inside of the barrel and reduce any increased tendency of the magnetized shot to wear or abrate the barrel as the shot is discharged therefrom.
