I am a dental hygienist now ( have been for 10 years).
I grab every piece of dental lead film I can find. I am on several dental office contact lists for their lead. It is soft and pure. Grab it while you can, as most dental offices are converting to digital ( non-US lead) xrays.
If the lead is from the room walls, double grab it. A lot of mass/weight of good soft lead. Might as well be a gold mine.
DO NOT take the protective "lead apron" they drape over you during stays. It is not lead. It is a rubber matte, infused with lead dust. Worthless for cast bullets.
Grab all the dental X-Ray lead or lead room shielding you can. It is good stuff for cast bullets. It is not radioactive.
If I had a source, I would grab it! Down to a few hundred pounds. Starting to get nervous. I hate the thought of buying from places like rotometals though.
