| 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. | ||||||
