hi I was looking at their molds, and it states they will work with their machines and clearly states they are designed to use RCBS handles if I remember right...as for the $75 if you have priced any of the other semi custom molds, $75 isnt out of line...I called them on their die prices as I have been tlaking to Mary at Magma and the price on Ebay was $45 and they said that was a mistake and changed the price to $35...I believe most of the prices are a buy it now...also one more thing I have found out is if you have a bullet mold and want the dies just fo it, especially if it has odd spacing for the lube grooves, you can either send them the measurement or a sample bullet and they will fix the die to match the needs...so far I havent ordered but in delaing on the phone they seem very nice..I keep watching old Stars with no paint going for new or more thna new prices and I think I will buy a new one...just my thoughts.WW1
