Mold diameter tolerance

Our bullet mold tolerance is stated diameter, +.003/-.000 inch.  We gauge our bullet molds with a "go/nogo" gauge, which tends to result in bullet molds that run on the high side of the tolerance.  You could probably use one of our standard molds at as-cast diameter with good results.

If the bullets are oversize or out of round the mold is not fully closing. A build up of lube, splash of lead, or a burr on the mold block faces are holding them apart. Inspect the mold block faces and carefully remove anything that might hold the mold apart. Make sure to lubricate the locating pins with solid alox/beeswax bullet lube, Lee part number 90007. If these steps are followed the bullets will cast dimensionally correct.
