RE: A duckhunting gun...
either the 11/87 or the 870 is nice on the upper scale a benelli is nice if you like semi autos but after shooting my brother browning citori i feel a need for a double barrel shotgun. i think he bought his used (very slightly the previous owner had it for a week and the action still had that slightly stiff feeling for the factory) for $1100 out the door. though it did have a tiny poke of a scratch mark.
if you want a 22rifle get a 10/22 that is if you want semiauto. though i think a 22 pistol is more fun

you can never have too many guns
