Lyman 3 die pistol dies

Most definitely expanders. I'm sure those are not Lyman parts, makes me wonder what the original owner was doing with them? Seems strange someone would get that elaborate for loading 9mm.

That was my thinking too. I'm not even using them since Lee powder thru die bells the case mouth enough for bullet seating. Only thing I could possibly see a use for these is to shape out of round casings.

Keep them around, funny how one sometimes finds a use for such things.

Makes me wonder if he was trying to make better handloads for a .38 S&W or 9mm Makarov or something. 9mm Luger is just too straight forward for much experimentation.

Love the so called obsolete stuff

^^^^^^^^^ yep, that was my first thought

The .380 part is obviously not functional. That's probably just the size of the round stock he used. 375 is 3/8". Or maybe that's the size he had to turn them down to to fit inside the die body.

He probably used these to expand the cases deeply. It looks like there's no flare step, though. Maybe he flared the case mouths in a separate step.

I have 2 expanders for 9mm. A 356/360 flare for jacketed and 356 cast, and a 358/362 flare for 357+ bullets. I have 2 expanders in 223, as well, one for jacketed and one for cast with a slightly larger flare step, 224/227. (Size of my cast bullets is 224).
