This topic can get quite cerebral. Non-enthusiast outsiders might consider it the stuff of an Aquinian colloquy, but it all adds to the joys and intrigue of shooting and gun ownership.
Aaron's post, as I understand it, is that after some experimentation he observed that chokes will alter a pattern as expected, and not render them modulated to the point of irrelevancy, when loading his shells using modern shot cups.
And do you remember the counter-intuitive arguments made about choke midway into the following thread -- one I am still transfixed by -- that choke OPENS a pattern?

Here is as I understand it a distillation of the audaciously unconventional points that were advanced by two of our members whose prodigious Parker gun erudition is regularly shared on this Forum:
***************
Dean R.: I had a 16 ga. Lifter that had been cut back from 28 to 24 so it effectively had no choke. But that little gun could really account for itself on 35, 40 and longer yardage clay targets. I was always amazed by how this gun would smash targets waay out there.

Edgar S.: "
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force."
Newton's First Law says to me that a cylinder bore will alter the direction and spread less than a choked bore. I have patterned a couple guns that have had their barrels cut to an extent that NO choke exists. I was amazed to see that the pattern is very much tighter than a lightly choked bore, up to a point where air resistance also begins to affect it.

Got that:
a cylinder bore will alter the direction and spread less than a choked bore.
