The balls pass the thumbnail test. I am sure that the lead has a purity of not more than two percent other stuff. I just got a bunch of wheel weights and will keep them separate because I think these will be not as pure. A tech rep told me they could be as high as seven percent tin or antimony.
I am starting the think that I need to move to wads. I would use felt, make my own and use my own lube. Crisco and wax rings.
The reason I am starting to think about wads is that the last time I went shooting, I realized how careless I am with lube.
