I use 9mm Lee dies on my Dillon (got the dies in a bad trade) for cheap 9mm. The lock rings have to be turned upside down and then only grip enough thread to hold.
The sizing die does not have a large enough cone to allow the case to slip in as easy as the Dillon dies. I have to push, pull or wiggle the case to go into the sizer. The 380 brass slips into the Dillon 223 die that I use to size them like a charm, so maybe I am spoiled, but I can crank out the 380's (and everything else) a whole lot faster than 9's.
They are also more involved to take apart to get clean when using lead bullets. About the same as RCBS. Again, comparing to Dillon.
Lots of people saying Lee works and they do, just slower for ME on my machine with my set of dies. With enough patience, anything will work. I must be short on patience, but I am too cheap to buy a set of Dillon 9mm for the amount that I load.
