I have a 44 cal mold that I would like to load for my Marlin 44 mag. I have a 300 grain gas check mold that I load for it. I have a Mihec PB 250 grain boolit that I have shot but not getting the results I would like. I probably wont shoot enough boolits to justify buying a check maker and would like to buy some PB checks to see if that helps. Thanks
