I have a lot of roofing lead. Seems very soft. Have cast lots of round balls with this kind of lead with good results.
Have tried one session casting 45-70 bullets with it. Did not experiment. Bullets did not fill out well, grease groves rounded over.
Is there a way to get good bullets with this lead without adding more tin?
Have been using RotoMetals 1 to 30 lead with good results, but the cost!!!
