A choke tube is a device that is attached to the muzzle of a shotgun. It is designed to control the spread of the shot and to improve the performance of the gun in terms of accuracy and range.
The most common type of choke tube is the full choke, which is intended to produce a tight pattern of a shot at long range. The full choke can be identified by its construction; it has a relatively small bore diameter, and it tapers sharply toward the muzzle. This design gives the full choke its characteristically narrow pattern.
The other common type of choke tube is the improved cylinder (also sometimes called Victory). Improved cylinder chokes are designed for short-range shooting, and consequently have a much wider bore diameter than full chokes. They also have a less pronounced taper, which gives them a correspondingly wider pattern of shot.
You might also encounter choke tubes labeled “modified” or “improved modified.” These are somewhere in between full and improved cylinders in their constriction and will produce patterns that are similarly intermediate in width.
A shotgun choke tube is a specialized internal component of a shotgun that attaches to the muzzle and restricts the spread of the shot. The constriction caused by the choke assists in patterns and increases accuracy. Chokes can be screwed into place or, more commonly, they are built-in and permanently affixed to the barrel.
Shotguns come in different sizes called gauges. The smaller the number, the larger the bore diameter. For example, 12 gauge has a bore diameter of .729 inches (18.5 mm), whereas 20 gauge has a bore diameter of .615 inches (15.6 mm). Another way to think about this is that 12 gauge is approximately 25% larger than 20 gauge—a significant difference. Larger gauges, such as 10, 8, and 4, are less common in today’s market but were once popular for hunting large games.
- The first thing to understand about shotgun chokes is that they come in different diameters that are expressed in thousandths of an inch (.000″). A full choke has the smallest diameter and provides the tightest shot pattern, whereas an open choke has the largest diameter and provides the loosest shot pattern. In between full and open are modified and improved cylinders.
- The second thing to understand about shotgun chokes is that they can be used with different types of shotgun shells. For example, you would not use a rifled choke tube with birdshot because the rifling would cause the pellets to spin and lose energy. On the other hand, you would not use an open choke with slugs because you want as much constriction as possible to stabilize the slug for greater accuracy.
- The third thing to understand about shotgun chokes is that they can be interchanged. Choke tubes are usually screw-in, meaning that you can remove the old choke tube and screw in a new one. This is a simple process that can be done in a matter of seconds.
Some shotguns come with fixed chokes, which means that the choke cannot be removed or replaced. In most cases, fixed chokes are full or modified. Full is the most common because it provides the best all-around performance for hunting and target shooting.
If you have a shotgun with a fixed choke, you can still change the constriction by using different types of shotgun shells. For example, if you have a full choke and want a more open pattern, you can use shells that have larger pellets. Conversely, if you have a modified choke and want a tighter pattern, you can use shells that have smaller pellets.
- The fourth and final thing to understand about shotgun chokes is that they wear out over time. The constriction will gradually increase as the metal of the choke tube wears down. This is why it’s important to check your choke tubes regularly and replace them when necessary.
To sum up, shotgun chokes are internal components that attach to the muzzle and restrict the spread of the shot. Chokes come in different diameters, which are expressed in thousandths of an inch (.000″). Full choke has the smallest diameter and provides the tightest shot pattern, whereas open choke has the largest diameter and provides the loosest shot pattern. Chokes can be interchanged, and they wear out over time.

A shotgun choke tube is a device that attaches to the muzzle of a shotgun barrel and restricts the spread of the shot pellets. The purpose of a choke tube is to improve the accuracy of the shots fired from the shotgun. Choke tubes work by constricting the diameter of the barrel at its muzzle end. This results in a tighter pattern when the shot pellets leave the barrel, making it easier to hit a target.
Choke tubes are available in different sizes, depending on how much constriction you want. The amount of constriction is measured in thousandths of an inch. The most common sizes are full (0.040″), improved cylinder (0.020″), and modified (0.010″).
You can also get choke tubes that are specifically designed for certain types of shotgun shells, such as rifled slugs or sabot rounds.
A shotgun choke tube is a device that helps to tighten the spread of pellets from a shotgun barrel. It does this by constricting the bore of the barrel at the end, which results in less pellet deformation and a more consistent shot pattern. The use of choke tubes can help improve your shooting accuracy, especially at a longer range.
Choke tubes come in different constrictions, or “chuck sizes,” which are expressed in thousandths of an inch (.010″). A full choke, for instance, will have a constriction of .040″. The tighter the constriction, the more effective it will be at tighter patterns, but also the more difficult it will be to hit your target.
If you are using a shotgun for hunting, you will want to choose a choke tube that is appropriate for the game you are hunting and the range you will be shooting at. For instance, if you are hunting ducks, you will want a more open choke such as an improved cylinder or skeet. If you are hunting turkey, however, you will want a tighter choke such as full or extra full.
Choke tubes are generally interchangeable between different shotgun makes and models, but it is always best to check with the manufacturer to be sure.
Choke tubes typically screw into the muzzle end of the barrel and can be easily removed for cleaning or changing.
A shotgun choke is a screw-in attachment to the muzzle of a shotgun that regulates the constriction of the shot pattern. The tighter the constriction (or “choke”), the more focused and less dispersed the shot will be.
Why would someone want to use a choke? There are several reasons. In hunting, a tightly-choked shotgun can be valuable for getting clean, ethical kills at a longer range than would be possible with an open-choked gun. In clay target shooting sports such as skeet and trap, chokes are often used to fine-tune the spread of the shot so that it better breaks targets. So here are some other questions, answered:
How does a choke tube work? The most simple explanation is that it acts as a constriction point at the muzzle end of the barrel, thereby narrowing and shaping the shot pattern.
What is the difference between “full” and “modified” chokes? The terms “full” and “modified” refer to how tight the choke is. A full choke will have the tightest constriction, while a modified choke will be slightly less constricted. There are also “improved” and “extra-full” chokes, which are even more tightly constricted than a full choke.
What is the difference between “internal” and “external” chokes?
Internal chokes are built into the barrel of the shotgun, while external chokes screw onto the end of the barrel.
