Only problem with that theory is the fact that lead is soft and can be easily molded by hand. Spent uranium on the other hand is what the military uses for armor plate on the Abrams tank among other things and it is virtually bullet proof and needs special artillery rounds to penetrate it. I have a hand time believing these materials are one and the same and think I would be getting another source of information to further investigate this little item. Doug Rupert
