Salve Demetrius,
I don't suppose the question was directed at me (didn't mention Plaster of Paris) but I can confirm PoP is good for making molds to pour lead into. I used to pour my own slugs for a small "cannon" I had made in PoP molds. To be on the safe side, I would suggest nice large airholes in the castmold. Lead has a relative low melting point, so you could melt it over a cooking gas flame in a deep ladle like I did. Mind the fumes!!
