bullet mold question

[res45]

I bought two Lyman molds one with handles at an estate sale for $25 each both still had the last bullets cast in them,I keep those bullets at my reloading bench as a reminder of the old gentleman caster.

I don't store my blocks with bullets in them,instead I just give them a good coat of USP Mineral Oil as Ed Harris instructed me to do,you don't have to wash the mineral oil off as as Mr. Harris told me it simply burns off when the mold is heated and will leave no residue.
