Front trigger / right barrel "Choke",
75% pellet count, 30" circle at 30 yards
Rear trigger / left barrel "Open",
75% pellet count, 30" circle at 20 yards
The first Skeet In / Skeet Out ?
Also, sounds a lot like the logic behind Winchesters WS2 / WS1
although a selective trigger required "Snicking" to make those true Skeet chokes.
