The advantage to using lead is that when it is pushed into the jacket, it does not recover, or bounce back at all, and retains the shape it was molded into. When compared to other materials, lead offers a higher density and less rebound, making it ideal for shaping and manufacturing into high-quality ammunition.

Lead is released into the air during burning coal, oil, or waste. … Lead is removed from the air by rain and by particles falling to land or into surface water.
