Key Takeaways

  • Choke tubes are tapered restrictions used to modify the spread of shot from a shotgun.

  • Different types provide different levels of performance, and selecting the right one for your specific shooting situation is essential.

  • Choke tubes can be used to customize shotguns, optimize shooting techniques, and maintain safety protocols for optimal performance.

Understanding Choke Tubes

Choke tubes are tapered restrictions at the muzzle end of a shotgun barrel, also known as a shotgun choke. Their primary purpose is to modify or form the spread of the shot as it exits the gun, creating a tighter choke or a more open pattern depending on the desired effect.

The introduction of choked barrels revolutionized shotgunning, enabling a shotgun barrel’s pattern and range to be modified and utilized effectively for numerous hunting and/or shooting applications, as steel shot patterns differently.

Types of Choke Tubes

There are several types of choke tubes available, including:

  • Full choke

  • Modified choke

  • Improved cylinder choke

  • Specialty chokes

Full, modified, and improved cylinder chokes are the most regularly used. For example, a cylinder choke, also referred to as a skeet or cylinder choke, is commonly used for law enforcement service shotguns. For waterfowl hunting, modified chokes are the go-to choice as they provide effective steel shot patterns for this type of game. On the other hand, full chokes are the top choice for trap shooting enthusiasts.

Specialty choke tubes are designed to provide enhanced performance in specific hunting and/or shooting scenarios, such as turkey hunting or waterfowl pass shooting, where a dense pattern is desired. Shot spreaders or diffusion chokes are designed to disperse the shot more effectively than a cylinder bore, thereby creating a wider pattern for close-range use. A popular example is the Briley Diffusion choke, which utilizes rifling within the choke to impart a slight spin on the shot, resulting in a wider spread, particularly useful when using steel shot as it patterns differently than lead shot.

Constriction and Its Effects

Constriction is the variation in diameter between the exit end of a choke and the actual bore of the barrel. The constriction range for chokes typically ranges from 0.00-1.15 mm (0.00-0.045 inch), with some relatively common turkey chokes reaching up to 2.50 mm (0.10 inch). Understanding how choke tubes manage diverse shot materials and their effective range and pattern is integral to selecting a suitable choke tube. The utilization of low-grade lead with a Full choke results in a broader pattern and fewer pellets in the head and neck region. Bismuth shotshells are legal for hunting waterfowl and suitable for use with older chokes as an alternative to lead shotshells.

The right choke tube for your specific shooting situation can make a significant difference. For example, a full choke is ideal for long-range shots, while an improved cylinder or modified choke would be more suitable for shorter distances. A grasp of how constriction impacts shot patterns and range equips you to make informed decisions on the ideal choke tube for your shotgun, leading to optimal performance in the field or on the range.

Ensuring choke tube compatibility with different shot materials is of paramount importance, as incorrectly pairing ammunition with the shotgun can cause harm to the firearm and create hazardous circumstances. Using incompatible ammunition may result in damage to the shotgun and may present potentially hazardous situations. For example, when using non-toxic shot shells in older shotguns, it is recommended to use a more open choke than one would for lead shells. Modern-day choke materials commonly make use of:

  • Stainless steel

  • Steel

  • Titanium

These materials are widely used in various applications.

Knowing the different types of choke tubes and their compatibilities is key to ensuring you’re using the appropriate choke tube for your ammunition. Understanding the relationship between choke tubes and ammunition compatibility helps you avoid potential risks and ensures the safety and longevity of your shotgun.

Patterning and Distance Considerations

Patterning and distance are critical factors when selecting a choke tube, as different firearms pattern differently. The only way to accurately assess the performance of a choke tube/load combination at distance is to pattern-test it on paper. To pattern-test a choke tube/load combination, shoot off a rest at a center mark in a 30-inch circle at 40 yards. This will help you understand the shot pattern and how well a tube will handle different shot materials and the effective range of the choke tube with various shotshells.

Testing your shotgun with different chokes and shotshells at various distances offers valuable insight into the best choke tube for your specific shooting scenario. Investing time to test and evaluate your options ensures that you’re making the optimal choice for your shotgun and shooting needs.
