MEC 600 dies and super sizer

[pawhitetail]

I have a mec 600jr pre82 model. It came with another loader I bought and it's setup for 16gauge. I don't have a 16 gauge so I am looking for the conversion dies for 20, 410 or 12 gauge so I can load something that I have a gun for.
I'm also looking for a 12 gauge mec super sizer to size the cheaper steel head hulls.
Thanks
