ABSTRACT:
A method of forming a gun ammunition projectile52including a leading end defined by an ogive53including the steps of admixing a quantity of a first powdered metal having a first melting point and a first density, with a quantity of a second powdered metal having a second, and lower, melting point and a second, and lesser, density, pressing a quantity of the admixed metal powders into a self-supporting compact having at least an outboard end disposing the compact in a cup-shaped jacket, heating the compact in the jacket, in a vertical attitude, to a temperature of at least the melting point of the second metal but less than the melting point of the first metal, for a time sufficient to result in a liquefied portion of the second metal migrating to and accumulating at the one outboard end of the compact.
