Joe, I wonder if it were possible for any one of us to measure shot strings out of several different guns, of several different gauges, using the same (let's say 1 oz.) payload, if there would be individual small bore guns that might have as short, or shorter, shoestrings because of the way the individual gun is bored, choked, the forcing cone in it, bore diameter, etc.
After reading Brister, and after 60 years of shotgun patterning, one thing I take away is that each gun is an individual, and if you try to fit them into a "mold" or make broad sweeping correlations about them based upon gauge, load, or even "common knowledge", you will be shown to be wrong at some point.
