Zusammenfassung:	A tungsten-tin composite for green (lead-free) ammunition is provided wherein the composite is made with a spheroidized tungsten powder and has mechanical properties similar to those of lead. The composite may be fully densified at pressures less than about 250 MPa and is suitable for pressing complex projectile shapes to near net size.
