That is kinda what it looks like to me from what I see...I don't work with cast much. The SWC look like they have a lub grove and a crimp grove. They should make a good looking load. Can you scratch either of them with your fingernail? It looks like they all should be run through a lubsizer and if the RN are the .3559 they may be 9mm. Alox is great or you can use some of the recipes out there.
I have a set of RCBS WC dies if you need them
