The RCBS dies are marked .38/.357. They can be used for both. You set the dies up for .38. If you need to load 357 they give you a washer that you add under the dies. This will raise them up to 357 length.
RCBS dies are the only ones I'm familiar with. I had a set of LEE dies I bought on EBay a long time ago. I used them once and set them aside. Now I can't remember what it was about them I didn't like.
I still have them if anyone wants them. I'd sell them cheap, say $20.00 plus shipping?
