摘要： A three component bullet with a core retention feature and a method of forming the bullet is described. The bullet can include a jacket surrounding a core and a locking band disposed around a circumference of the jacket and the core. The locking band can be received in a circumferential depression formed in the jacket and the core such as by compressing the core to cause the core and the jacket to expand radially fore and aft of the locking band. The circumferential depression can include shoulders that are in compressive engagement with the locking band to help secure the locking band in place. The circumferential depression can include an inwardly-extending annular band of jacket material which embeds itself into the core material with the result that the core is locked inside the jacket.

摘要： A three component bullet with an improved core retention feature and a method of manufacturing the bullet includes 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, 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 non-rigid locking band. A relatively tight-fitting punch enters the open end of the pre-form, to radially swell the core and subsequently portions of the jacket fore and aft of the non-rigid locking band, thereby securing the non-rigid locking band in place. An inwardly-extending annular band of jacket material embeds itself into the core material to lock the core inside the jacket.

摘要： A low-cost, reduced friction expanding bullet with an improved core retention feature and a method of manufacturing the bullet is described wherein a cylindrical jacket containing a compacted malleable metal core having an open end and a closed end 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 and wherein a transition shoulder separates the two diameters. The pre-form is then placed in a profile die wherein a base punch exerts an axial force against said pre-form which axially collapses a portion of the jacket wall forward of the transition shoulder subsequently forcing said portion of the jacket wall radially inwardly providing a reduction in bearing surface and forming an internal core-locking radius while at the same time forming an ogival bullet nose. The bullet thus formed provides reduced friction and ultimately higher muzzle velocity per any given chamber pressure level while also providing a core-locking feature comprising a wide-area, circumferential indentation which serves as a living hinge that ultimately expedites uniform bullet expansion.
