Abstract: The invention relates to sintered iron bullets having increased frangibility (or which can be easily fragmented) and to the materials and processes for the manufacture of such bullets. The bullets of the present invention are typically made from iron powder (including powdered iron from scrap iron) which are pressed to form a briquette and then sintered under conditions so as to obtain bullets with the desired level of frangibility. In the preferred embodiment of the invention, the bullets are resin or plastic impregnated and then coated to facilitate lubricity and prevent corrosion.
