20-Gauge Turkey Gun: Choosing the Best Shotgun for You

A 20-gauge shotgun can be an excellent turkey gun for adults and young hunters alike, provided it fits the shooter and produces a dependable pattern with a legal turkey load. A pump is a practical starting point for value and simplicity, while a gas-operated autoloader deserves consideration if recoil is a concern. The right choice comes down to fit, carry weight, ammunition compatibility, and what the gun actually does on paper, not its advertised reach.

20 Gauge vs. 12 Gauge for Turkey Hunting

A 20 gauge is a smaller-bore shotgun than a 12 gauge, but it is not merely a beginner’s gun. Its appeal for turkey hunting is straightforward: many models are relatively light, compact, and comfortable to carry through the woods.

A 12 gauge generally offers heavier shot-payload options. That can provide more pellets, but it does not automatically produce a better pattern or make a poorly judged shot acceptable. A well-matched 20-gauge gun, choke, and load can be a capable turkey setup within a sensible hunting distance.

Recoil is the important qualification. A light 20 gauge firing a heavy turkey load can still kick sharply. Gun weight, ammunition, action type, and stock fit all affect the shooting experience; gauge alone does not tell you how comfortable a shotgun will be.

Choose the 20 gauge when its handling and fit benefit you. Choose the gauge you can shoot comfortably and confidently. Neither gauge can substitute for pattern testing.

How to Choose and Set Up a 20-Gauge Turkey Gun

Use the action type to narrow your shopping list before comparing individual models.

Action	Best Reason to Consider It	Main Trade-Off
Pump	Practical value and a straightforward, manually operated action	The shooter must work the fore-end fully between shots
Gas-operated autoloader	Recoil comfort and no manual cycling between shots	More attention to cleaning and ammunition compatibility
Single-shot	A simple break-action layout	Reloading requires opening the action; light models can recoil sharply
Over/under	Using a familiar double-barrel field gun	Each barrel needs its own pattern and point-of-impact check

Step 1: Choose an Action You Can Operate Comfortably

Handle the candidate shotgun unloaded. Keep the muzzle pointed in a safe direction, keep your finger outside the trigger guard, and have the seller demonstrate its controls.
Check your reach. You should be able to operate the safety and action without struggling to maintain control. With a pump, pay particular attention to whether you can comfortably reach and fully move the fore-end.
Judge the complete package. Compare the gun, any needed sight or mounting hardware, compatible choke options, and the ammunition required for testing, not just the price on the tag.

A turkey-specific model can save shopping for separate accessories. It is not automatically better than a field gun that already fits and has the features you need.

Step 2: Compare Carry Weight and Stock Fit

Compare exact configurations, not gauge labels. The Mossberg 500 12-gauge configuration in Mossberg’s comparison weighs around 7.25 pounds, while its Mini 510 Youth Super Bantam weighs 5 pounds, over 2 pounds less to carry. Those figures belong to the guns in that comparison; confirm the manufacturer’s specifications for the exact model you are considering.
Account for accessories. A sight, mount, sling, and other additions change the finished gun’s weight and balance. The lightest bare shotgun is not necessarily the easiest finished setup to hold steady.
Check stock length with the gun unloaded. Shoulder it in your hunting clothing and from the position you expect to use. Your shoulder contact and sight alignment should feel natural rather than forced.

For the adjustable-stock Mini 510 Youth Super Bantam setup featured by Mossberg, sliding the stock forward shortens the reach for a smaller shooter; moving the stock back provides more length for a larger shooter. The setup includes an added adjustable stock, so do not assume every factory Mini 510 has that mechanism. Confirm the stock fitted to the exact gun and use its manufacturer’s adjustment instructions.

A youth or compact designation describes fit, not who is allowed to use the gun. It can suit an adult with a shorter reach, but an excessively short stock is no bargain if it compromises comfortable handling.

Step 3: Check Hunting Law and Ammunition Compatibility

Check the current turkey regulations for your hunt. Hunting law varies by state and season. Defer to the applicable state wildlife agency for legal firearms, ammunition, permits, and season requirements.
Check pellet-size restrictions before buying loads. For Missouri turkey hunting, shot larger than No. 4 is prohibited, according to the Missouri Department of Conservation (MDC). Confirm the current applicable regulations before hunting. Shot numbering runs backward: a smaller shot number generally means a larger pellet.
Match ammunition to the shotgun. Use the gauge and permitted shell length identified by the gun’s chamber markings and manufacturer documentation. Never use a shell longer than the chamber rating, and keep different gauges of ammunition separated.

“Turkey load” on the box does not establish that ammunition is legal in your state or compatible with your gun. Shot material also matters when checking barrel and choke compatibility.

Step 4: Select a Compatible Choke and Sighting System

Start with a suitable turkey choke. An extra-full choke is a common choice for concentrating the pattern in a turkey’s vital head-and-neck area, per MDC. It is a starting point for testing, not a guarantee of the best result.
Confirm the exact fit and ammunition approval. Choke thread systems, constrictions, and permitted shot materials vary by model and brand. Verify compatibility with the shotgun, choke, and ammunition manufacturers before firing.
Choose a sight you can use consistently. A bead may be sufficient if the gun places its pattern where you aim. Adjustable sights or a red dot can help establish a precise aiming reference, but they must be securely fitted and checked on paper.

Do not buy a choke by gauge alone: a 20-gauge tube must also match the shotgun’s choke system. Likewise, a tighter choke is not automatically better with every load.

Step 5: Pattern the Intended Turkey Loads

Use an appropriate shooting range. Wear eye and hearing protection, use a suitable backstop, and follow the range’s firing and cease-fire procedures whenever placing or checking targets.
Compare several legal, compatible loads. Common turkey shot sizes include No. 4, 5, and 6, per MDC. Pattern several sizes and select the load and shot size that work best in your gun rather than choosing by reputation alone.
Use a large paper target with a clear turkey head-and-neck aiming area. Begin at a close, measured distance to establish where the pattern lands, then test at the distances you intend to hunt.
Record the combination and result. Mark the load, choke, distance, and aiming point on each target. Look for repeatable coverage of the vital area rather than a few scattered hits or one unusually good target.
Confirm both pattern placement and consistency. A dense pattern centered away from your aiming point is not a successful setup. Resolve sight alignment or point-of-impact problems, then retest before hunting.

If the pattern becomes sparse or inconsistent, shorten your intended hunting distance or test another compatible combination. Do not let one encouraging target outweigh repeated poor ones.

Supported range shooting establishes what the equipment can do. You also need to be able to hold and aim the gun steadily from your intended hunting position.

Step 6: Set Your Shot Limit and Finish the Range Session

Set a conservative outer limit. Keep turkey shots within 40 yards; the Missouri Department of Conservation recommends against longer shots regardless of shotgun gauge. This is field guidance, not a universal legal distance limit.
Shorten that limit when conditions demand it. Your usable distance may be less because of your pattern, shooting position, visibility, or ability to judge range. Take a shot only at a positively identified legal bird with a safe background and a clear target. Pass if you cannot establish those conditions.
Finish with the firearm secured. Unload, verify that the chamber and magazine are empty, and follow range procedures before collecting targets. Secure the unloaded shotgun and ammunition appropriately when finished.

If you have not established a dependable pattern and correct point of impact, the setup is not ready for hunting. Resolve the problem and repeat the paper test.

TSS Turkey Loads and Long-Range Claims

A load’s ability to produce a distant pattern is only one measure of its field performance.

TSS, tungsten super shot, is denser than lead. That allows ammunition makers to use smaller pellets while retaining useful pellet weight, potentially putting more pellets into a given payload. This is one reason modern 20-gauge turkey loads attract attention.

That advantage does not remove the need for compatibility checks or pattern testing. Nor does a distant paper target reproduce a moving bird, an awkward seated position, uncertain range, or an obstructed view.

Treat additional pattern capability as useful margin.

TSS is also not mandatory for every hunter. A legal conventional load that patterns reliably at your intended distance can be a sensible choice. Select ammunition on demonstrated performance, compatibility, legality, and cost, not the assumption that the most expensive shell must be necessary.

When Your Existing Field Shotgun Is Enough

You may not need a dedicated turkey gun at all. A familiar 20-gauge field shotgun can serve well if it is mechanically sound, accepts suitable ammunition, and produces a reliable pattern where you aim.

A shorter barrel can make a shotgun easier to maneuver around cover or inside a blind. Do not replace a familiar field gun solely because its barrel is longer than the barrels on turkey-marketed models.

Camouflage finishes and specialized furniture are secondary to fit and verified performance. Factory sight-mounting provisions can be convenient, but a new optic is not automatically required.

For an older or used shotgun with uncertain condition, chamber markings, or choke compatibility, have a qualified gunsmith inspect it before firing. Do not guess about ammunition approval or try to make an incompatible choke fit.

Confirm Your Turkey Gun Is Ready

Before hunting, make sure you can answer yes to these checks:

Fit: You can shoulder the gun naturally in your hunting clothing and operate its controls comfortably.
Compatibility: The gun, choke, and chosen ammunition are approved to work together.
Legality: You have checked current state wildlife-agency requirements for the hunt.
Consistency: Repeated targets support your chosen hunting distance.
Field judgment: You are prepared to pass on an uncertain, obstructed, or unsafe shot.

Keep the tested combination documented. Changing the choke, ammunition, sight, or stock fit means verifying the setup again rather than assuming its performance is unchanged.

Your next move is a measured paper-target session with the exact setup you plan to carry, not another accessory purchase.

Frequently Asked Questions

What Is the Best 20-Gauge Pump Shotgun for Turkey Hunting?

For a 20-gauge pump turkey gun, compare a turkey-specific model with a field model that fits you and accepts suitable ammunition. Neither is automatically best for every shooter. Compare the exact stock fit, fore-end reach, choke system, and sighting provisions rather than choosing by model-family name alone.

What Is the Best 20-Gauge Autoloader Turkey Shotgun?

For a recoil-conscious shopper, compare models that fit you and function reliably with your chosen ammunition. Gas operation can soften felt recoil, but the gun still needs to fit you and function reliably with your chosen ammunition. Confirm the exact configuration and current availability rather than assuming every package has identical features.

What Is a Good Single-Shot 20-Gauge Turkey Gun?

A simple break-action shotgun is an option to compare if you want straightforward operation. A single-shot can make sense for a hunter who values straightforward operation, but a light example may recoil more sharply than expected. Check fit and ammunition compatibility before choosing it for a young or recoil-sensitive shooter.

What Is a Good 20-Gauge Over/Under for Turkey Hunting?

A familiar 20-gauge field over/under can work if the intended barrel produces a dependable pattern at the aiming point. It is usually more sensible to evaluate a double you already own than to buy an expensive one solely for turkey hunting. Pattern each barrel separately if you intend to use both, because their points of impact may differ.

How do you choose the best 20-gauge turkey shotgun to buy?

Choose a 20-gauge turkey shotgun that you can carry and handle comfortably, then identify its best load and choke by patterning it at the range. An extra-full choke is commonly used because it creates the tightest pattern. Try several shot sizes in your own gun and keep the combination that patterns best.

How far can a 20-gauge shoot a turkey?

Keep a 20-gauge turkey shot within 40 yards, because shots beyond that distance are not recommended for turkeys with any shotgun gauge. Pattern your gun using several shot sizes so you can choose the load that performs best in that specific setup.
