All my pistol dies except on my Dillon Square Deal, of course, are the three die Lee sets. I really like the Lee taper crimp dies, though, for auto pistols. I have a Lee Pro 1000 progressive, now, that works if you get the routine down, not a great press, but all my Lee stuff works on it. I do .357 and .45ACP on it. My Dillon is a PITA to change calibers on, so it's just set up for 9x19.
I don't have a rifle die EXCEPT for 7.62x39, in Lee dies. They're all Hornady, RCBS, or old Pacifics. I'm not sure why, but I just don't buy Lee rifle dies. I'm sure they're just as good. I like the Hornadys, good value. I use the Lee pistol dies for the powder through expander with the Lee auto disc measure. It's quite fast and easy to use and is required on the progressive. I have another measure, but like the auto disc and even use the measure to dole out powder for a few rifle calibers with a double disc conversion. I do 7.62x39 and .308 Winchester with it.
