the judge is a example of what is being suggested. in a normal 410 the pattern is good out to 40-50 yds for small game. BUT if the same shell is shot with a judge with a 4 in barrel, the pattern is usless past 20-25 ft for game! why? because the pattern opens up so much faster and their isnt enough shot density to do the job.
the same would hold true reguardless of the guage used. its physics, no way around that hurdle.
The Judge isn't a typical short-barrel either though...it's rifled. The rifling is what is causing the extreme pattern spread.
Take a rifled slug barrel on a full length shotgun and pattern it next to a similar length/choke smoothbore barrel. The pattern will open up faster due to centripedal force from the spin imparted by the rifling, not the barrel length.
Forcing cone and choke are the predominant factor in determining how a shotgun barrel perform, length has little to do with it except some velocity loss as it gets shorter.
