So Im melting down my range lead and pulling out the copper jackets from them. I am getting small amounts of lead remaining inside, that I've tried to get out buy can't seem to always get the last little drop out. So I'm wondering if there are tips to get it all out, or is it not always that big of a deal to others? Also how picky will the scrap yard be when i take this copper back with a small amount of lead with them? Thanks
