1. From copper jacketed bullets that lose some of the jacket while exiting the case.
2. From using cast bullets.

4. The case had fallen into a container of leaded gasoline.
5. The 3 year old has scribbled all over the case.
I am waiting for someone to ask how lead dust can get into the tumbling media. No one has asked, so I will. How does tumbling brass contaminate the tumbling media with lead????
