Just as a side answer my favorite 2 of several shotguns are my Grade VI 28ga Browning Lightening single trigger and my 12ga solid rib Berreta ASE double trigger and I can assure you when a covey gets up I usually get (and hit ) two birds, with either gun. As long as we are on the subject it also amazes me WHY the dinky little splinter forearms are so prized. Then the people who shoot them on shotguns have to have the leather contraption to slide down over the barrels to keep from burning their fingers. A well fitted beavertail solves this problem but is I'm sure more difficult to fit. Lest you think I have no experience with S/S double rifles I have owned Cogswell Harrison,Geyger,Chapuis,Several Merkels in mostly big calibers including 470 and 450/400. My current double is a Merkel S/S 8x57JRS model 141(with single trigger) as I have probably done my last hunt in Africa.
