RE: Casting Temperatures......................
I agree that iron or steel moulds remain more uniform in temperature after they are at the correct heat. RCBS moulds are excellent, but I have had good results with Lyman, NEI and Rapine moulds as well. I have also had good results with SOME Lee moulds, but not all of the ones I have. I think Lee moulds are a little trickier to use, because one MUST maintain a specific casting rythme, due to the fact that they not only heat up fast, but they also cool off faster than iron, steel, or brass moulds.
