Okay, I've seen a .410 frame converted to a double 8X57, IIRC.
Many single barrel shotguns have rifle barrels up to .30-30 caliber readily available.
At the top end, Krieghoff and Merkel will retrofit their double 12s to .470 NE, but do require the receiver back for proof testing. Which implies that the receiver as built can take the load.
Just how big/powerful a cartridge can the standard shotgun receiver take? I would assume as long as the pivot bar is solid and the locking mechanism, that the straight back recoil on a cartridge head shouldn't be a problem.
Anyone with experience or breech pressure numbers to toss out?
Thanks
