I'd like to see the same size action as well. I'm not convinced there would be that much difference.

I do know that from correspondence I had with Merkel about the 70's vintage Model 8 shotgun that they were in fact identicle actions. When i asked about any difference in heat treating I was told that there isn't any because it was simpler to get all the actions hardened the same. I didn't ask about their current actions and if this is still the case however.

I also know that I had 2 Sauers checked. One rifle one shotgun and they run same rockwell hardness and the actions dimensions are identicle.
