Would make an excellent Snake Gun!

Actually had something similar once, a Charles Lancaster 4 barrel pistol that has been re-chambered from .455 to .410 shotgun.

Used to take it Trout Fishing - accounted for a few Black Snakes! Well, you've just fought you way through a mile of Blackberries to get to a nice run, and there's a Black Snake hogging the spot that you want to cast from - what else would you do?

Careless Black Ducks were known to pay the ultimate penalty as well!
