I believe the Sicilian name for an 8-10" SxS is a lupara... problem with a lupara or a howdah is you only get one or two shots, great if you get the first or last hit in but not so much if the other guy still wants to play after you've run out. I'd probably go with a reduced-recoil deer slug load...
Mini shell slugs would likely be a better choice. 2-3/4" Managed recoil slugs are babies in a pump compared to full power slugs, but I think would still be a recoil wallop in a break action with pistol grip and potential to lose teeth if brought up to eye level.
