In the country of the blind, the one-eyed man is King.
IF I lived in one of the areas where I could not own a modern firearm, and C&B revolvers were not banned (or regulated as tightly), I would not hesitate to keep one loaded for that purpose.
And I would pay whatever it took to get my hands on a Ruger Old Army. It is in no way historically accurate, but it is powerful, reliable, and mine is bidding fair to be the most accurate handgun I own. With a full load of 2F goex, a lubed felt wad, and a .457" RB, it will cut one (not very) ragged hole at 20 yards. IIRC, using my volume measure, it was a full 45 gr of powder, and it just left room to seat the wad so that it didn't interfere with the ball when it was placed in the chamber mouth. 2F wants a good bit more ramming pressure than 3F does.
