With the price of all moulds rising..........even to the point of stupidity for Lee moulds. It make more sense, than ever, to buy custom. Might as well get what you pay for.
I suspect that is why Tom is slammed. Currently, his website says ten week wait. I just purchased a replacement sprue plate for one of his three cavity brass moulds. Arrived in less than one week. Original was too long, for my taste and had the optional trough................which I don't care for when ladle casting. My correspondence with Tom, told me that he didn't make that sprue plate. He apparently jobbed them out, back then.
For comparison. Top is the original spare plate. Replacement is the same configuration as the 4 cavity iron, shown.
