You guys are killing me. All I shot last season was a 28 gauge Beretta A400 with Hevi-X 4’s. That’s pretty much all we shoot, and nearly all our ducks are mallards. Heck, I even used the 28 while hunting honkers and doubled with it from a decent sized flock. Haven’t hunted ducks with a 12 gauge in 5 seasons and haven’t missed it a bit.
