Ive only casted 200 or so boolits so far with a lee 255g swc in .452 . Up until now I've only used 50/50 NRA lube applied by hand and liquid x lox tumble lubed both with good results . A friend offered to tumble some in Moly with his jacketed stuff . I gave him 100 boolits to tumble and then j started reading discouraging results. Should I try them ? With or without additional lube ? If I melt them back down will it ruin my alloy or will it flux off ?
