I just stumbled across an article by a chap who makes soft point hard cast boolits. Apparently he casts in soft lead then puts the resulting boolits in a gauge he's made and cuts the base off. He then refills his furnace with hard alloy, puts the tips back in the mould and pours hard alloy on the back of them. Would this method bond the two parts together ok? I was a little sceptical as I was always led to believe the pour should be done in one go?
