Salvaging -purifying mixed alloys ?

[Dan Cash]

I have used some mixed, crystaline looking metal that I softened as much as I could with reasonably pure lead and it worked ok if I was careful with my casting. Not sure I shoot well enough to tell the difference but don't think I have missed any targets because of the alloy. High velocity smokeless paper patch bullets for target work don't seem to care what they are cast of as long as the mould fills out. Don't want them too brittle for game though.
