Happy new years everyone. I am new to boolit casting, never done this before. I've been studying it for some time now, especially on this site. Also study the Lyman CB handbook 3rd ed.. I have a question about how to alloy lead.
I have purchased some scrap lead sash weights to use for casting boolits. Wheel weights are no longer available in Washington state. It appears to be very soft lead, I can easily scratch the surface with my fingernail. After I smelt it down, I'm planning to add tin and antimony to create a harder alloy for my big bore rifles? I was planning to buy some tin and antimony from Rotometals, the tin in short cut wire shape and the antimony in shot form. I'm worried about the antimony, will using pure antimony shot be difficult to get it to alloy with the lead? I notice that the melt point for pure antimony is quite a bit higher than normal smelting temps. I'm wondering if I would be better off to forget the separate tin and antimony and use something like solder or linotype to increase the hardness of my lead alloy? Any help would really be appreciated to get me started on the right path. Thanks. Jeff
