Never cast very many bullets, just a few for a friend, using his molds, but my plumber's pot and lead pouring equipment. I did, however, make a large number of sinkers of various types and sizes, as well as trot line weights. It was definitely an outdoor project. I did occasionally have to put up a windbreak, but always just to protect the pot. I kept my head in the open, and never over the pot. Always well clear of it.
I never had enough nerve to use regular leather gloves, especially to handle the metal ends of the molds. It was always either insulated gloves, fireplace gloves, or forge gloves.
That was nice work.
Just my opinion.
