In barrels shorter than about 4 inches the muzzle pressure at shot exit is higher, which tends to open patterns if the shot are not contained in a plastic shot cup or wrapper.

Oh yes, that big hole on the right bottom of the paper is the plastic wad, that was still traveling fast enough at 25 yards to pop a hole in the paper.
Now this is just for the reference records, so if you ever get asked, or need to compare for decision making it's there for you.

The general moral of the story being when it comes to open choke, the longer the barrel the better.

I also have an open choke barrel that I did a "jug choke" on. I found that it does work, and I closed the pattern from 30% to close to 45%, but it was a crap load of work and took some specialized tools. You are not going to do it with a dowel and sandpaper no matter what the guy on you-tube said.
BTW these were factory shells with plastic shot wads and cups. 1oz. of 7 1/2 chilled lead shot. All from the same box.
