The Jug Choking process is from the past...modern chokes are modern, not traditional.
I had Lowell choke one .62cal at "Full" for a Turkey, Trap, tall tree shots at squirrels, etc, and it's outstanding...took a couple turkeys this spring at 40 & 30 yards with head shots.
Had him choke another barrel to Imp. Cyl. PLUS (between an I.C. and a modified) for general purpose small game, doves, crows, etc.
And as DaveK mentioned, it doesn't change the ability to load bore size wads like the physical constriction of a modern choke does...ie: a lubed cushion wad that gets compressed being pushed through a modern full choke tube, would not then be a tight fit and not give a tight seal in the cylinder size bore behind the modern choke.
