Keeping in mind each gun is an individual; I see little difference in full choke patterns from a 20" or a 28" barrel.
That right there is the truth. The choke will have the greatest effect. Barrel length will have a little to no discernible affect on pattern or velocity as shotguns do not act like rifles.
Barrel length really has an effect on what YOU are comfortable with. I pheasant hunt with a 26" 20ga, duck and goose hunt with a 28" 12 gauge and shoot trap with a 32" 12 gauge. Each serving the best purpose for MY needs.
