Interesting! I have never ever cast lead and never plan on it. Funny story though, when I was growing up many people on the block were bass fisherman, including my pops. The family 5 houses down made their own jig heads. They were BEYOND generous and gave everyone some jig heads growing up. We thought they were awesome neighbors. It came out years later, the parents were sending the kids out on their bikes and stealing the lead counter weights off tires to make jig heads. I died laughing when I finally found out, but many on the block were very upset. I thought it was kind of ingenious but naturally a tire is much mor expensive than lead.This is 2 dozen for $73 with free shipping! That is a very good deal. Less than $3 each. If you can do it cheaper, I would be surprised. I am always scrounging lead and have a stockpile, but it takes hours to mold and propane to burn to make that many weights. There is a sweet spot on the lead temp and the mold temp. Go to fast and you have weak anchors, go too slow and they don't pour smooth, and you need to recast it.
