Understanding Choke Tubes: Precision at the Muzzle
What are Choke Tubes?
A shotgun, unlike a rifle, disperses multiple projectiles (shot) with each pull of the trigger. The way these shot pellets spread out, or the shot pattern, is crucial for effective target engagement. This is where the choke tube enters the equation. It’s essentially a constriction located at the muzzle of the barrel that shapes and controls the spread of the shot. This constriction influences the density and diameter of the shot pattern at various distances.
Types of Choke Tubes
Choke tubes are typically classified based on their degree of constriction. Different constriction levels impact the pattern size. For example, a tighter choke, which is more constricted, results in a narrower and denser pattern at longer ranges. Conversely, a less constricted choke generates a wider pattern, ideal for closer targets.
Consider the difference: a full choke, known for its substantial constriction, will produce a tight pattern suitable for distant targets like waterfowl. Conversely, an improved cylinder choke, offering less constriction, creates a wider pattern perfect for fast-moving targets at closer ranges like upland birds or home defense scenarios.
Materials and Construction
Beyond constriction, different materials are used in the construction of choke tubes. Modern choke tubes are often crafted from hardened steel, sometimes with finishes that resist corrosion. This ensures durability and longevity, especially when used in challenging environmental conditions. The quality of materials plays a significant role in both the tube’s performance and its lifespan.

Choosing the Right Choke for Your Needs: Matching Tool to Task
Factors to Consider
Choosing the right Accu-Choke for a particular task is a fundamental skill for any Mossberg 500 owner. The right choice comes down to several factors.
The first, and possibly most important, factor is the intended use of the shotgun. Are you primarily hunting upland birds, waterfowl, turkey, or engaging in clay target sports? Each of these activities has different demands.
The type and size of the shot being used is crucial. Different shot sizes and types (birdshot, buckshot, or slugs) require different choke constrictions to perform optimally.
Shooting distance has a significant impact on choke selection. Closer targets generally benefit from more open chokes, while longer-range targets need tighter chokes to maintain pattern density.
Choke Tube Recommendations by Application
Here’s a breakdown of some recommendations based on application:
For hunting small game, a more open choke, like Improved Cylinder, is often ideal. It provides a wider pattern at close to moderate ranges, ensuring a higher chance of a successful hit on fast-moving targets.
For upland birds like pheasant or quail, a Modified choke strikes a good balance between pattern density and range. It will provide a tighter pattern to effectively reach a wider range and reduce the risk of blowing a pattern too wide on a closer shot.
When waterfowl hunting, especially for ducks and geese, a Full or a tighter choke is often preferred. These constrictions deliver a dense pattern at greater distances, maximizing the chances of bringing down birds at the longer ranges often associated with waterfowling.
For turkey hunting, specialized turkey chokes are often employed. These chokes are designed with extremely tight constrictions to deliver dense patterns at extended ranges, making the most of the available range.
In clay target sports like skeet and sporting clays, shooters will often use more open chokes such as Improved Cylinder or Modified for the closer ranges and a tighter choke for longer distances.
Home defense might call for an Improved Cylinder or even a more open choke, depending on the range within your home. Buckshot often works well with a less constricted choke for close-range engagements.
Matching Chokes to Ammunition
The pairing of choke tubes and ammunition is critical to achieving optimal performance. Experimentation is key, so consider shooting at a pattern board to see how your preferred ammunition performs with different choke combinations. A general rule is that a tighter choke usually works best with larger shot sizes and vice versa.
Barrel Length Consideration
Finally, consider the barrel length of your Mossberg 500. Longer barrels often offer more consistent patterns, but shorter barrels are still adaptable with the correct choke choices.
Installing and Using the Accu-Choke System
Installation Steps
Installing an Accu-Choke tube is a straightforward process, but it’s essential to follow the steps carefully. Begin by ensuring the shotgun is unloaded and the action is open.
Next, use the choke wrench to loosen the existing choke tube (if present) by turning it counterclockwise. Once loosened, carefully remove the existing tube.
Before installing the new Accu-Choke tube, make sure the threads in the barrel are clean. You can use a brush and solvent if necessary.
Carefully insert the new Accu-Choke tube into the barrel and use the choke wrench to tighten it. Be careful not to overtighten the tube. Overtightening can cause damage.
Maintenance Tips
Regular maintenance is essential. Clean the choke tubes regularly to remove any buildup of fouling or debris. Also, inspect the tubes for any damage.
Always prioritize safety when handling firearms. Ensure the gun is unloaded before attempting to change a choke tube.
Optimizing Your Shotgun’s Performance: Beyond the Choke
Patterning Your Shotgun
To truly master your Mossberg 500 and its Accu-Choke set, you must learn how to pattern your shotgun.

This test is critical for understanding how your chosen choke and ammunition combination performs. It provides feedback and helps you select the most effective loads for hunting or shooting.
To pattern your shotgun, set up a large target (like a piece of cardboard) at the desired distance. Then, take several shots and carefully examine the resulting pattern. You can then determine the shot distribution and the density of the pattern.
Cleaning and Maintenance
Cleaning and maintaining your shotgun, including the choke tubes, is also crucial for optimal performance. After each shooting session, clean the barrel and the choke tubes with appropriate cleaning supplies. Remove any buildup of fouling, powder residue, or debris.
Regularly check your Accu-Choke tubes for damage. Any dents, bulges, or wear on the threads can affect the pattern. If you find any damage, replace the tube immediately.
Slugs and Sighting
If you intend to use slugs, your shotgun may need to be sighted in. Slugs, single projectiles, require precise aiming, and the sight alignment on your Mossberg 500 is crucial.
