I asked a few local tire shops that already had lead collectors to save me the stick on weights, for black powder bullet casting. One guy was nice enough to put aside a full bucket- about 25 pounds- almost all steel, only got about 2 ounces of lead! Another shop I do much better, apparently the guy running the balancing machine has a lot of wastage with the stick-ons, and they still use the soft lead stuff- I'm getting about 30-40% , much of it new looking and clean, some with the double-sided tape still intact. I keep them supplied with coffee money and get more than enough for my needs.Everybody's happy.
