My shotgun is a 12-bore. I'll need to take some photos.

What cartridges could a conversion double rifle be made from it?

Like the larger heavier Greener Empires, perhaps .577 LNE?

I'm after a nice .375 Flanged though, scoped. As I've mentioned before.

While the slight case colour hardened action, plain, is not too bad. The walnut stocks are plain. Possibly need restocking. Overall it would be quite a plain Jane double rifle. A sidelock like that Saraswueta would be fantastic instead.
