I've a friend that loads both 24 & 32 ga. Spoke w/him this afternoon specifically because of this thread before responding. He uses two of the older Texan/Sovereign single stage loaders, DP2's(?)made prior to the FW's and had them converted w/the aid of some judicious fabrication and machine shop work. Uses mostly star crimps and 800X powder. He has the roll crimp tools as well, but said they were not available when he had those presses modified. Said that he preferred the Cheddite hulls to the Fiocchi's because of the amount of plastic that is folded over the base wad before the head is crimped on during manufacture.
Just thot to pass it along, should it prove of value to your inquiry.
