125 gr cast gc loads

Just start with jacketed data. you can swap a cast bullet into a jacketed load with no increase in pressure, cannot go the other way though. I'd pick a reasonable load for a 125gr jacketed and reduce 10% and work up. I've shot the lee HBC 200gr and have had good luck with 15gr of H4227.
