BoingBoing posted this image of a ring made from a mushroomed bullet. I was horrified to see that they had used a lead bullet.
Lead is toxic and should not be worn in contact with the skin. I have been tested for lead poisoning and if you shoot a lot, so should you. The symptoms are nasty.
I got myself tested not because I was worried about symptoms but because at the time I was shooting a few times each week and I wanted a baseline figure for the amount of lead in my body.
