RCBS used to make 12 gauge dies for that press, you have to take out the thread adapter as the die body is bigger, I bought a set used that I found in Australia but I have yet to try them out.
Yeah. The answer is yes, IF you can find the dies.
The bushing that screws into the top of the press has to be removed, the dies are 1 and 1/4 inches (by unreliable memory) or so in diameter.
The Lee Classic cast has the same style removable bushing for the larger size dies.
The dies seem to have dropped out of the commercial world, though.
In truth, I would think you can pick up a shotshell press for less than what you will pay for the dies, unless you are very lucky.
It's not that it can't be done, rather, not very many bother to go that way these days.

I'm thinking the answer is a big no but need to confirm. I have an RCBS RockChucker single stage press and recently bought a shot gun. Can I use the single stage press to load 12 guage?
If no, what you recommend.
Take a good look at the Ponsness Warren shotshell presses. I started with Mec and then went to PW. I would never go back.
I've never used one, but the MEC 600 Jr. sure looks well built and has legions of satisfied users.
If I ever get into shotgun reloading it will be the press I buy.
