ABSTRACT:
The invention provides a zinc alloy die cast bullet (100) and a method for manufacturing the same for use primarily in indoor shooting ranges. The use of a zinc die cast alloy eliminates toxic lead vapors and dust which result from the use of lead in bullets. The bullet (100) is made by heating a zinc metal alloy to a molten state (30), injecting the molten alloy into a preformed cavity within a mold under a pressure (20, 60), and sizing the cast bullet at a temperature greater than 70.degree. F. (30, 70).
