A cartridge's diversity is limited only by the imagination of the shooter. Some years back I spent some time shooting paper patched round balls for the .44 Mag, and found accuracy with one ball quite good at 50 yards, 2 balls worked quite well also, but printed two groups of about 1.5" spread, about 3" apart. Never quite figured that out, but the single ball load was good on squill and other obnoxious critters. I wouldn't call them mouse fart loads, the last round of single ball loads crossed the Chrony at about 2400 fps. Not very accurate but fast enough to catch the Road Runner.
