The Mossberg 500 is a legendary pump-action shotgun, renowned for its reliability and versatility. Adding a 20 gauge slug barrel transforms this already capable firearm into a potent and accurate platform for hunting larger game or engaging in long-range shooting. This guide delves into the specifics of Mossberg 500 20 gauge slug barrels, covering key features, considerations, and frequently asked questions.
Why Choose a 20 Gauge Slug Barrel for Your Mossberg 500?
While 12 gauge remains the dominant choice for slug guns, the 20 gauge offers several compelling advantages:
-
Reduced Recoil: The lower recoil of a 20 gauge makes it significantly more comfortable to shoot, particularly for novice shooters or those with less upper body strength. This translates to better accuracy and faster follow-up shots.
-
Lighter Weight: A 20 gauge slug barrel, and the shotgun itself, is generally lighter than its 12 gauge counterpart. This is advantageous for extended hunting trips or situations demanding maneuverability.
-
Improved Handling: The lighter weight and reduced recoil contribute to improved handling, making the gun easier to swing and maintain target acquisition.
-
Lower Ammunition Cost: 20 gauge slugs are typically less expensive than 12 gauge slugs, though this depends on the specific ammunition chosen.
Key Features to Consider When Choosing a Mossberg 500 20 Gauge Slug Barrel
Several features distinguish different 20 gauge slug barrels for the Mossberg 500. Understanding these differences will help you select the barrel best suited to your needs:
Barrel Length:
-
Shorter Barrels (e.g., 18.5 inches): Offer increased maneuverability but may slightly reduce accuracy at longer ranges. Ideal for close-quarters situations or hunting in dense cover.
-
Longer Barrels (e.g., 24 inches): Generally provide greater accuracy and less muzzle rise, improving long-range performance. Better for hunting open areas or target shooting.
Rifling:
Most slug barrels feature rifling, which imparts spin to the slug, improving accuracy and range. Different rifling patterns (e.g., rate of twist) can affect bullet stability and accuracy. Consider the type of slugs you intend to use when making your selection.
Sight Options:
Various sight options are available, including:
-
Bead Sights: Simple and reliable, but less precise for longer ranges.
-
Ghost Ring Sights: Offer a wider sight picture, improving target acquisition.
-
Scope Mounts: Allow for mounting optics like scopes for enhanced accuracy and precision at extended ranges.
Choosing the Right Ammunition:
The performance of your Mossberg 500 20 gauge slug barrel is heavily influenced by the ammunition you use. Experimentation is key to finding the load that provides the best accuracy and consistency with your specific barrel and shooting style. Consider factors like:
-
Slug Type: Foster slugs, sabot slugs, and Brenneke slugs all have different ballistic characteristics.
-
Slug Weight: Heavier slugs generally have better penetration but increased recoil.
-
Muzzle Velocity: Higher muzzle velocities translate to flatter trajectories and longer ranges.
