I save a lot of soft lead from jobs that I do. I had about 12 five gallon buckets of it and this winter while I was using the wood burners I decided to melt it down and pour it into 1lbs ingots. Worker real well as I had several cast iron lead pots and would fill them up and set them inside of the wood burner to melt down. Worked well as all the bad smoke went up the chimney and outside. When I was finished and this did take a couple of weeks to get it all done I had over 500lbs of lead.
This is all soft lead and great for making round balls for muzzleloaders and fishing weights. In order to use it in rifles and handguns I add wheel weights to it at a rate of 7lbs of soft lead to 3lbs of wheel weights to a batch and get #2 lead that is hard enough to fire in cartridge guns.
