Smyth Busters: Do Rifled Shotgun Slugs Require a Rifled Barrel?

Published on February 2, 2021
Duration: 2:26

This video debunks the myth that rifled shotgun slugs require a rifled barrel. It clarifies that rifled slugs are designed for smoothbore barrels, using helical fins for stability. Conversely, sabot slugs, which are lighter and longer, necessitate a rifled barrel for the sabot to engage the rifling and provide gyroscopic stability.

Quick Summary

Rifled shotgun slugs are designed for smoothbore barrels and use helical fins for stability. Sabot slugs, however, require a rifled barrel, as their plastic sabot engages the rifling to provide gyroscopic spin and accuracy.

Frequently Asked Questions

Do rifled shotgun slugs require a rifled barrel?

No, rifled shotgun slugs are designed for smoothbore barrels. They have fins that help them stabilize in flight without rifling. Using them in a rifled barrel can actually damage the fins and reduce accuracy.

What type of shotgun slug needs a rifled barrel?

Sabot slugs require a rifled barrel. These slugs feature a plastic sabot that engages the barrel's rifling, imparting spin and gyroscopic stability necessary for accurate flight.

How do rifled slugs stabilize in a smoothbore barrel?

Rifled slugs have helical fins molded into their design. These fins help the slug spin as it travels through the air, providing stability without needing the rifling found in a gun barrel.

What happens if you shoot a sabot slug from a smoothbore barrel?

Shooting a sabot slug from a smoothbore barrel will result in poor accuracy. The sabot needs the rifling to engage and spin the projectile; without it, the slug will likely tumble unpredictably.
