Almost all my molds are Lee and of those , most are 6 cavity in the calibers that Lee sells them .
Any time I get a lee mols , I scrub them well with an old tooth brush , tooth paste ( mild abrasive ) & warm water . Rinse well and let dry VERY WELL !
I turn my melting pot to 100% and pour bullets until they start coming out well . Turn the melting pot to " normal " and continue casting .
This seems to accelerate the " break in " process and I not have to break in do that mold again .
Warning , do not let the lead get too solid / hard , before you cut the spru . I made that mistake a couple of time and broke the cam that opens the sprue plate the first bit , on the 6 cavity molds .
The wooden handles will probably get loose , just mix up some J B Weld and glue the handles on . It seems to survive the heat just fine .
The 6 cavity molds are the way to go .
God bless
