If you want LEAD let me know.
If you want carp use wheel weights. You get to sort them to remove the zinc, you'll get maybe 70% yield if you're lucky and it will pour like carp on a lot of molds. Not to mention it will void what little warranty you get with a Lee pot.
I'll provide smelted lead to TFF members for $1 a pound + shipping.
