ABSTRACT:
High specific gravity, lead free shotshell pellets are produced by preparing an iron-tungsten alloy having a specific gravity of at least 8 g/cc, melting the alloy at a temperature of about 1550.degree.-1760.degree. C., pouring the melted alloy through at least one orifice of a sieve having a specific sized opening so as to produce a desired final product size, and allowing the melted alloy to fall by gravity through a gaseous medium to form drops of molten metal, and cooling the individual molten drops to form spherical metal pellets. A plurality of orifices of different sizes may be used in order to form a desired distribution of shot pellet sizes.
