One of my old hunting buddies back in WI used a Franchi AL-48 20ga with 24" barrels he was hard on birds, not many got away. My X-FinL used a Rem. Model 31 Skeet 12ga again a superb shot on grouse. Sorry no pics of grouse, my little Bernardelli Elos 12ga 25" IC/IM is the king of the woods for me, it is lightning fast and with an oz of 6's or 7's B&P High Pheasant rounds is my favorite.
