Arsenic Present in lead. A small amount is necessary in the production of small shot since it increases the surface tension of dropped lead, thereby improving lead shot roundness. Copper Bullet Core Alloy Increases hardness. Tin Increases hardness. Constituent Comment Copper Jacket alloy metal Zinc Jacket alloy metal Iron Iron tips on penetrator rounds PAHs (Polycyclic Aromatic Hydrocarbons) Concentration of PAHs in clay targets varies from one manufacturer to the next, but may be as high as 1,000mg/kg. Existing studies show that PAHs are bound within the limestone matrix of the target and are, therefore, not bioavailable.
