pattern a .410 with the smaller casings, and you will get an idea of how that .44 with the 48" barrel will pattern. Not very well. The shot column is too long, allowing most of the pellets to rub against the side of the barrel. Very little shot makes it to 30 yards still in some kind of pattern. The 24. ga.(.579") is a good gauge, but not popular here, inspite of all the .58 cal guns that have been sold here. The 28 ga.(.550") seems to be the most efficient gauge for delivering good patterns with choke, of the small gauge guns. You almost can't find a 28 ga. gun that does not shoot well, and its darn hard to find them on a used gun rack!
I would leave the .44 and .45 cal guns for roundball use, only, and if I wanted a shotgun of small bore diameter, I would get a 28 ga. gun. Extremely light loads, no recoil, and very efficient for taking birds out to 30 yards, and some a bit further. Unlike modern cartridges where you are restricted to small charges of shot, in a ML shotgun you can all more shot if you think you need it, or if you think it helps the pattern at the longer ranges.
