Posts #11 and #12 in this thread provide info. about how to load shot without special components and using only newspaper as wad material. --->>>

A long time ago someone described how he experimented to make a paper cartridge to hold a load of shot together for use in a rifled barrel, but it would be very difficult to find the posts by doing a search.
Essentially he used the stiff paper board from a frozen vegetable container to wrap up a load of shot in a tube, then perhaps he had put some slits in it so that it would delay opening up until the load was on the way to the target.
His experimentation may have allowed him to shoot a squirrel a 20-25 yards.
But I don't know how fast the twist rate of the rifling was in his gun.
Otherwise like others said, the fast twist rifling and lack of choke constriction will spread out the shot pattern.
Wrapping up a load of shot in a paper tube might be the only way to help overcome the spinning effect of the rifled barrel.
Then the gun and tube of shot would need to be properly loaded and held in place in the bore.
The trick would be to experiment with how to construct the tube, and how much shot and powder to use just to see if it could be made to work reasonably well.
A sabot could probably be used as a base wad for shot if you have any of those.
And a person doesn't need to load a ton of shot or a bunch of powder to try it.
Maybe a small load of powder and shot will provide some entertainment to try patterning it at 10 or 20 feet.
Then come back to this thread and tell us how you loaded it and what your results were.
I remember someone posting how they loaded some kind of filler like grits or Cream of Wheat in their revolver to shoot bees around their property at very close range.
Who ever said that insects won't make for some good hunting fun.
Or maybe you can bring some frog legs home to put on your table.
