Yes the first is the percentage of tin followed by antimony and lead.Ozarkridgerunner wrote:I don't know that I would get into casting my own bullets like many of you do but it is very interesting. Again I appreciate all the advice. It's one of many reasons I like this forum so much. 220, out of curiosity, in your first post about those ratios you listed. Are those numbers representing the percentages of lead and alloys you use like antimony and zinc , etc.? And I guess you conduct your own b/h test on your hand made bullets ?
2:6:92 is the alloy most commercial casters use for their hard cast.
Even in Aus their are a few smelters that produce lead ingots for bullet casters in just about any alloy you want. If you have known alloys it is quite simple to combine them at ratios to give the desired alloy. I do have a cheap BHN tester that is handy with unknown alloys
Ammo manufacturers should be able to tell you the alloy of their cast loads, a quick email might get the answer.
I had no intention of casting my own but was unhappy with the results I was getting with commercial cast.
My very first go was with a cheap lee tumble lube mould, an old saucepan and a gas camp stove, lubed them with LLA and shot them unsized. Though a 357 revolver groups were less than half the size of my best results with commercial cast, I was hooked and now cast from 22-45cal
