Rifled vs Smooth Bore Barrel

Published on September 26, 2015
Duration: 5:52

This video demonstrates the practical difference in accuracy between rifled and smooth bore shotgun barrels when firing slugs. Lead Firearms Instructor Matt Carriker uses a football spiral analogy to explain how rifling stabilizes projectiles. Testing with 12 gauge 1 oz slugs at 75 yards shows a tighter group with the rifled barrel, though the difference is less pronounced at typical hunting distances with simple sights.

Quick Summary

Rifled shotgun barrels have spiral grooves that spin slugs, stabilizing them for better accuracy, much like a football spiral. Testing shows rifled barrels produce tighter groups with 12 gauge slugs at 75 yards compared to smooth bore barrels, though the difference is less critical at very close hunting ranges.

Frequently Asked Questions

What is the main difference between rifled and smooth bore shotgun barrels?

Smooth bore barrels are designed for firing shot or saboted slugs without imparting spin. Rifled barrels have spiral grooves that spin slugs, stabilizing them for significantly improved accuracy and range.

Does a rifled barrel make a big difference for shotgun slugs?

Yes, a rifled barrel makes a noticeable difference. In testing, a rifled barrel produced tighter groups with 12 gauge slugs at 75 yards compared to a smooth bore barrel, demonstrating enhanced accuracy.

When is the accuracy difference between rifled and smooth bore barrels most important?

The accuracy advantage of a rifled barrel is most critical for longer shots beyond 50-75 yards. For typical hunting distances under 100 yards with simple sights, the difference is less pronounced but still present.

Can you shoot rifled slugs through a rifled barrel?

Yes, rifled slugs are designed to be fired through rifled barrels. However, for optimal accuracy, slugs specifically designed for rifled barrels (often sabot slugs) are recommended.
