ABSTRACT:
A non-toxic shotgun pellet having ballistic characteristics similar to those of lead shot is made up of particles of a first alloy, containing primarily ferrotungsten, suspended in a matrix of a second alloy, containing primarily lead. The relative amounts of lead and ferrotungsten are selected to minimize cost while keeping the overall lead content to forty percent or less, by weight, to avoid toxicity. The first alloy is formed by diluting the ferrotungsten with iron or steel and carbon at temperatures on the order of 1800.degree. C. in an inert gas environment. The alloy is quenched and then crushed into particles over which is poured the second alloy comprising lead, tin and antimony in order to suspend the first alloy particles in the second alloy mixture.
