Setting Up a Shotgun for Waterfowl and Upland Birds

A single 12-gauge can hunt everything with feathers in North America if it is set up for the job in front of it. The setup changes between a duck blind and a pheasant field far more than most new hunters expect: different shot, different chokes, a plugged magazine, and often different clothing on the shooter that changes how the gun fits. This guide covers what a waterfowl and upland shotgun needs, what the law requires, and how to move between the two.

The gun

For waterfowl, a 12-gauge with a three-inch chamber in a pump or a gas- or inertia-operated semi-automatic is the standard. Synthetic stock and a weather-resistant finish matter more than wood in a wet blind. A twenty-six or twenty-eight inch barrel swings smoothly on passing birds. For upland birds a lighter gun carries better over miles of cover; a 20-gauge or a light 12 with a twenty-six inch barrel is ideal, and a double gun with two chokes is the traditional choice. Many hunters do both jobs with one 12-gauge autoloader and simply change the choke and the shells.

Non-toxic shot and the plug

Federal law requires non-toxic shot for all waterfowl hunting: steel, bismuth, tungsten alloys or one of the other approved types, never lead. It also requires the shotgun to hold no more than three shells, so a pump or semi-auto magazine must be plugged with the wooden or plastic dowel that comes with the gun. Check the plug before the season; a game warden will. Lead shot remains legal for upland birds in most states, though not on many federal refuges and some state areas, and non-toxic loads for upland birds are increasingly common.

Chokes for steel and lead

Steel shot is harder than lead and patterns tighter through the same choke, so a modified choke with steel throws roughly what a full choke does with lead. Use modified or improved modified for ducks over decoys and improved modified for geese, and never fire steel through a full choke unless the tube is marked for it. For upland birds with lead, improved cylinder for close-flushing quail and grouse, modified for pheasant. Pattern the gun at forty yards with the load you will hunt; the results are often surprising.

Shot sizes

Teal and small ducks over decoys: steel number 4 or 3.
Mallards and large ducks: steel number 2 or 3, three-inch shells.
Geese: steel BB or BBB, three or three-and-a-half inch; tungsten loads let you drop a size.
Quail and woodcock: lead 7½ or 8.
Grouse: lead 6 or 7½.
Pheasant: lead 5 or 6, or non-toxic 4 where required.

Decoys, calls and the rest of the kit

The shotgun is the cheapest part of a duck hunt. Waders, a dozen decoys, a call, a blind bag and a dog that retrieves are what actually put birds in hand, and a first-season hunter does better spending on those than on a second gun. For upland hunting the kit is lighter: a vest with a game bag, boots that survive briars, blaze orange where the state requires it, and water for the dog. A cleaning rod in the truck saves a hunt when a barrel is plugged with mud from a fall.

Youth and small shooters

A 20-gauge with a youth stock and light loads is the right first bird gun for a small or young shooter; a 12-gauge pump with three-inch shells will teach a flinch that lasts years. Many makers sell compact models with stocks that can be lengthened with spacers as the shooter grows, and a gas-operated 20-gauge semi-auto is the softest-shooting field gun there is.

Fit in heavy clothing

A gun that fits in a shirt at the clays range is too long in a duck blind in December with a parka and a life jacket on. Many waterfowl guns are ordered with a shorter stock or have a spacer removed for the season; an inch of length of pull makes the difference between a smooth mount and a butt caught in the coat. Upland guns fit as they do at the range because the clothing is lighter. A recoil pad that does not snag helps in both.

Sights and optics

A bead is all a wingshooter needs, and a bright fibre-optic front bead helps in low light. Red dots on shotguns are for turkey, not birds; the eye must stay on the bird, not the sight.

Licences, stamps and hours

Waterfowl needs the state licence, a state migratory bird or waterfowl permit, HIP registration and the federal duck stamp for hunters sixteen and over. Shooting hours are set by federal rule, generally a half hour before sunrise to sunset. Upland birds need the state small-game licence and, in some states, a pheasant or upland stamp. The state rules guide lists the agencies.

Caring for a wet gun

Salt marsh and rain get inside a shotgun. Strip it after every wet hunt, dry it, oil the metal lightly and leave the action open to dry overnight. Gas systems on semi-autos foul with heavy loads and need cleaning every few hundred rounds. A cheap synthetic-stocked pump survives neglect that will ruin a fine double.

Dogs and etiquette

Upland hunting is a dog sport, and safe gun handling around dogs and other hunters is the first skill: muzzles up, safeties on until the bird is up, and no low shots at birds a dog might be under. In a blind, agree who shoots which birds before the first flight.
