Hey all, new to the forum, I know that many like to mix plumbing solder in with their lead to make alloy. I work in a plumbing shop and we go through solder like no tommarow, I’ve started to collect the scrap drippings, since lead is a bit hard to come by here in Cali sometimes. I’ve done some mixing with lead and it works fine but have since started to cast with straight solder ingots. This is 97/3 Tin/copper solder and it produces a shiny lightweight but very hard bullet.casting with a lee 124gr 356 produces an 88gr bullet and a 230gr .452 makes a 151gr bullet lubed with alox. I loaded a box of 9mm and 45 and cleaned my pistols then fired a full box into a steel sillouette at about 30yds, all seemed to fly straight and there didn’t seem to be much leading if any at all and fouling was acceptable, going to load more and post chrono results as well
