Do I Need A 12 Gauge To Hunt Ducks?

By: Scott Haugen Published on August 10, 2023.

Do I need a 12 gauge shotgun to hunt ducks? It’s a simple question, but the answer can vary from person to person, even hunt to hunt. Here are some points to consider in determining if a 12 gauge shotgun is the right choice for you and your waterfowl hunting excursions.

Let’s start with the obvious. Any 12 gauge 3-inch shotgun shell will hold more pellets than a 16, 20 gauge, or smaller bore shooter. Whether steel shot, bismuth, tungsten, or a blend, a 12 gauge shell will always put more pellets in the air than lesser gauges shooting the same size shot. Simple math tells us the more shot in the air, the greater the likelihood of hitting your target.

Another obvious fact is a 12 gauge shotgun produces more recoil than any of the lesser gauges. If recoil is not a concern and you want the best odds of hitting a flying bird by optimizing the shot count, then the question of whether you need a 12 gauge to hunt ducks has just been answered.

Is Recoil a Concern?

But what if recoil is a concern? Or what if you're only shooting at decoying ducks as they drop into the spread inside 30 yards? With close shots at slow-moving birds comes an increased ability to look down the barrel, acquire a target, pull the trigger, and cleanly kill a bird. Because of this, a smaller bore shotgun than a 12 gauge can be easier to manage, thus increasing shooting accuracy. At the same time, if recoil finds you flinching or not following through on your shots, then a sub-gauge could be a better choice.

How Are You Hunting Those Ducks?

Other points to consider in determining if a 12 gauge is what you need for ducks is the type of hunting you’ll be doing. If you're pass shooting ducks or taking them as they swing by the outskirts of your decoys, then a 12 gauge is a good choice because it puts more pellets in the air.

Tough Ducks and Geese

If you're going to hunt diving ducks, sea ducks, or geese of any kind, then a 12 gauge is an intelligent choice. Not only will more pellets help knock down these tough birds, but the increased energy a 12 gauge delivers will optimize the penetration, which is vital as winter progresses, and the density of waterfowl feathers increases.

Wind and Hunting with Others

If you hunt where the wind often blows hard, or gusts many days of the season, then a 12 gauge could be what you need. Even if shooting ducks as they backpedal into the decoys, on high wind days, they can go vertical and quickly gain distance. With sub-gauge shotguns, you may not optimize the pellet count or speed to reach these ducks, and this is a situation where a 12 gauge has you covered.

If you hunt a lot with other people, a 12 gauge can be a wise choice because it can sometimes be a race to shoot ducks as they come in. If you’re shooting a 20 gauge and everyone else in the blind is shooting a 12 gauge, and they pull the trigger 10 yards before you're even considering shouldering your shotgun, it can be a very frustrating day. Having a 12 gauge to compete and keep up with fellow hunters makes the hunt more enjoyable.

The 12 Is Tough to Beat

Let’s take it one step further and combine the previous scenarios. Say you’re hunting in high winds, and everyone in the blind is shooting a 12 gauge shotgun, but you're the only one with a sub-gauge. Should this happen, ensure you sit on the end of the blind that will get the first shots at approaching ducks. If you’re stuck on the wrong end of the waterfowl fort, you might not get a shot all morning with your sub-gauge.

Due to the higher pellet count and energy, a 12 gauge is excellent for follow-up shots on birds already hit. If you must keep shooting at a hit bird, a 12 gauge will increase the odds of hitting it as it quickly gains distance from your shooting position over 16, 20, and 28 gauge shotguns. Again, it's simple math, and we all know how important it is to connect on follow-up shots.

If a crippled duck or goose sails into the water or across a field and you don’t have a dog, you want as many pellets as possible coming out of the barrel to finish it. When in flight, a duck and a goose are large targets. But get them on the ground or the water, and their heads become the target, and these are tiny kill zones. This is where optimized payloads are essential and where a 12 gauge offers a noted advantage.

Pattern For Success

As with all shotguns, pattern the loads you plan on hunting with before the hunt. Steel can pattern differently than bismuth which patterns different than tungsten. The choke you use can also cause various types, sizes, and blends of shot to fly differently from one another. Be sure you know how each load patterns, as a shim adjustment or a choke change may be necessary to maximize shooting accuracy.

Go Sub-Gauge When Solo

A 12 gauge may not be your go-to shotgun if you hunt ducks and geese alone. When hunting alone, you’re in control of many variables. You set the decoys how you want them, reposition them when necessary, put the blind where you want it, do the calling, and take each shot under your terms. For this controlled, solo hunting type, a sub-gauge may be a better choice for hunting

Age Matters

If you’re an aging hunter or have a small frame, a 12 gauge may be too much to handle. You could shoot a 12 gauge and downsize loads, but reducing the gauge, not the ammunition, is a better choice, especially if the 12 gauge is heavy and too long to manage physically.

Get Both!

If you hunt on your own and with others, then having a 12 gauge and a sub-gauge shotgun to hunt with is an option. Even when hunting alone on windy days, or if pass shooting or jump shooting late-season ducks, having the extra punch a 12 gauge packs can make a big difference in optimizing your shooting success. Then again, hit those calm days or hunt over decoys in a tiny creek, and a 20 or 28-gauge is plenty if you can shoot with accuracy. Then again, anytime you’re with a group of hunters shooting 12 gauges, your experience will be more positive if you’re shooting the same bore.

Final Thoughts

Do you need a 12 gauge to hunt ducks? Maybe, maybe not. The answer lies in the many factors surrounding every hunt you go on but ultimately hinges on how well you can swing a 12 gauge and how accurately you can shoot it.
