Continuing to learn and accumulate experience with boolit casting and I've come to a firm conclusion that some of my lead needs to be alloyed...primarily with tin to improve flow characteristics and mold fillout (edges are rounded and almost cartoon-like, not sharp and crisp).
Found some "Lead Free" brand pluming solder at the local hardware store that was $6.99 for 3oz of 95sn/5sb. This is outrageously expensive for my means.
What I want to know is what do you guys use to improve your tin content, where you get it and how much you fork out.
