Quick Answer
Different barrel lengths can affect shotgun accuracy with slugs, with optimal performance typically achieved between 18 and 24 inches. Longer barrels tend to reduce recoil and improve accuracy at longer ranges, but may decrease velocity and increase overpenetration.
Rifled Barrels and Slug Performance
When using rifled barrels and slugs, a longer barrel is often preferred for its ability to stabilize the slug’s flight and improve accuracy. This is because the rifling imparted to the slug helps to straighten its trajectory and reduce wobble. However, the optimal barrel length for slugs can vary depending on the specific load and the intended use of the shotgun. In general, a 20-inch barrel is a good starting point for most slug loads, and can provide a good balance between accuracy and velocity.
The Importance of Barrel Length and Slug Type
When choosing a barrel length for slug shooting, it’s essential to consider the type of slug being used. Heavier, more aerodynamic slugs such as the Brenneke or the Federal Premium may require a longer barrel to reach optimal velocity and accuracy, while lighter, more traditional slugs may perform well in shorter barrels. In general, a longer barrel can help to reduce the effects of wind and range, making it a good choice for longer shooting distances. However, it’s also worth noting that longer barrels can increase recoil, which may be a concern for some shooters.
