Anyone know if the Lee 6 cavity molds are able to hold up to zinc alloy temps?
I spray my molds with graphite spray, after 300 bullets I might see a spec of graphite missing from an edge of the lube groove. That's with lead.
I'm curious if that will help keep it from damaging the mold from the excessive heat people claim some aluminum molds suffer
I'm thinking about making up a batch of zinc bullets for plinking and knowing I'm not getting the bullet back. " Shooting in the desert, or range "
