I was wondering if anyone has tested a 9mm hollow point mold for expansion? I'm thinking about getting a hollow point mold next year to replicate my carry ammo, and was wondering if I could see similar expansion with cast lead. I currently carry 147 grain Hornady XTP's and have found a few molds that are a similar shape. A member here also sent me a PDF drawing replicating the XTP design.
What alloy would be best for a cast lead hollow point? I'm assuming lower antimony content would provide better expansion, but I don't really know for sure.
I'm not saying that this would be my carry ammo, only that I would like to know if I can get reliable expansion in the event that I can't get jacketed hollow points.
