A method of forming a gun ammunition projectile including a leading end defined by an ogive including 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 than said first metal, pressing a quantity of said admixed powdered metals into a self-supporting compact having at least an outboard end, introducing said compact into a cup-shaped jacket, having an open end, with said outboard end of said compact disposed internally of and adjacent said open end of said jacket, heating said compact in said jacket to a temperature of at least the melting point of said second metal but less than the melting point of said first metal, for a time sufficient to result in a liquefied portion of said second metal migrating to and accumulating at said one outboard end of said compact, said accumulated second metal being disposed within said jacket.
