I have a Slazenger .410 bolt-action shotgun, the one they (rather crudely) made out of shot-out SMLE No.1 MkIII*s just after WWII as an 'orchard pest gun'. They're reasonably rare, only 7000 or so were made. It's not a repeater though, single shot only, so there's no real benefit to be had. It does handle 3" shells like a champ and has accounted for several rabbits and dozens of clays over the past few years.
The Sportco Model 81 and 83 are on my 'to acquire' list, though for collection purposes rather than any practical field use. I think there's a very good reason why double barrels and semi autos (where possible) still rule.
