This is exactly right. And a good example is special purpose Turkey shotguns. they rarely have longer than 20" barrels and yet they shoot the tightest patterns of any other shotgun.
I cut my 870 back to 19" and had the barrel re-reamed and threaded for the rem chokes. I run a jellyhead ported Turkey tube and a 2 rd mag tube extension. It is one of my fav clay pidgeon guns and can bust em 50 yds out or more.
