Been thinking about a .375 Winchester double rifle for decades. A guy could build himself some shotshells using the .375 case for up close grouse work, and have a pretty fine woods shotgun/rifle combo. For my purpose, I'd want it to carry more like a featherweight SxS shotgun than a 12 pound behometh.
What are the odds all the stars would align and it could happen? Could a SxS shotgun serve as a donor action? Pressures for the 375 Winchester would perhaps overwhelm the shotguns receiver rating?
I would look for .405 Winchester double. Belgian ones from respectable makers show up now and then eg Raick Freres, Le Forgeron,......
