I have been on a tear with the 6 banger Lee copy of the HG 68 45 SWC lately. Must be closing in on 5000 boolits cast with this mold. Once it is up to temp it casts nice boolits fairly quickly and empties the pot in a hurry. I was wondering if I need to be on the lookout for the mold wearing out. Anyone ever worn out an aluminum mold? What should I be looking for as signs of trouble? All my other molds simply do not get the volume that this one sees, and I suspect that the old school steel molds probably will never wear out unless I let them rust badly.
