Hello. I found this wonderful site a few months back and finally made the plunge. I love older-style firearms and cast boolits. Single action revolvers, single shot and lever rifles, Elmer, Skeeter, John Taffin, Brian Pierce, etc. I lurk over at sixgunner.com, leverguns.com and a few others. I know LAH and had the pleasure of spending a day with this wonderful gentleman a few years back at a shooting get-together in Pennsylvania. My primary, burning question regards how to ID bad wheelweights BEFORE they go into the pot. I know to keep the melt temp around 600-650(?) to avoid melting zinc. What about these scratch tests, bend tests, etc.? What do the bad ones bend, scratch, look and sound like? Any info would be greatly appreciated! And yes, I am hopelessly addicted to casting my own some day, but for now just ingots for a rainy day. Thanks!
