Abstract
Tungsten powder is mixed with a second powder metal and a binder to be used as small arms projectiles and shot pellets for use in shot guns which is cost effective to produce and which can perform ballistically. Ballistic performance equal to or superior to that of lead would be offered by a material having a specific gravity equal to or greater than lead. The non-toxic projectiles are manufactured in a cost-effective process; yet still produces projectiles and shot pellets that can perform ballistically. This projectile composition can perform substantially as well as lead and lead alloys or better without the need to fabricate the composition from a high temperature molten state which requires large amounts of energy input. In one particular embodiment of the invention, the tungsten powder is blended with iron powder and Portland Cement for constructing projectiles. The tungsten, iron and Portland Cement (W/Fe Portland cement) shot provides a satisfactory substitute for lead shot.
