Geo , what shot gun do you like for your calling ? I used a Benelli left handed for the plane , as you shoot from the port side of the plane and behind the pilot so the spent hulls went to the back of the plane , and a cheap Mossberg out of the chopper . What shells do you prefer for your calling . I don't often call in close cover but still have had some land close enough to touch them that came from behind or from the side or out of a sage brush choked draw to my front . For calling when denning I carried the Mossberg with my 223 but most often used the 223 . The Mossberg had a 20 " barrel with a modified choke I ran 2 3/4 " #4 buck when I could or ,BB'S then #4 shot . What barrel length and choke do you like ?
