In 1958, my dad had a gunsmith cut two inches off the 26" barrels of his recently acquired 20 ga Superposed. Said it shot too tight and no one seemed able to open the choke enough to suit him. Then to "balance" out that activity, he took a rasp to the stock and hollowed out an area along the top, just below the comb. Did a decent job of refinishing the stock. After he got it "right" He probably shot a million quail with that gun. I have it now, found a used set of 26" barrels as a replacement, and refinished the wood. But it still has that modified stock as a remembrance.
