Many years ago I found a Craigslist ad for lead blocks that came from a medical building that was being destroyed or renovated. So I bought 100 or 200 pounds. I’ve only used it for making surf fishing spider weights. Anyone have a rough idea or experience on the metal composition and hardness for X-ray wall blocks?
