A shotgun’s barrel is smooth on the inside, while a rifle’s barrel has spiral grooves cut into it. These grooves are called “rifling.” The rifling in a rifle’s barrel makes the bullet spin as it leaves the barrel. This spinning makes the bullet more accurate over long distances. A smooth bore shotgun’s barrel does not have rifling. This means that the slug (bullet) does not spin when it leaves the barrel.
Advance Tips: Can You Shoot Rifled Slugs Through A Smooth Bore Shotgun

A smooth bore shotgun is designed to fire pellets or shot. The rifled slug is a single projectile with spiral grooves cut into the surface of the slug. These grooves give the slug a spin as it leaves the barrel. The spin stabilizes the slug in flight, much like the rifling in a rifle barrel.
Smooth bore shotgun cannot impart the same spin to the slug, so it will not be as accurate as a rifle. The smooth bore also has a wider pattern, making it less effective for long-range shooting.
Smooth bore shotgun can, however, fire a rifled slug accurately enough for most hunting and self-defense situations. The key is to use the proper ammunition and to understand the limitations of the smooth bore.
There are two types of rifled slugs: Foster and sabotaged. The Foster slug is a traditional lead slug with spiral grooves cut into the surface. The sabot slug has a plastic or metal jacket that covers the lead slug. The jacket has spiral grooves that engage the rifling in the barrel.
The sabot slug is more accurate than the Foster slug because the jacket provides a better gas seal. This gives the sabot slug a higher muzzle velocity and less bullet drop. The sabot slug is also more expensive than the Foster slug.
The Foster slug can be used in any shotgun, but the saboted slug must be used in a shotgun with rifled barrels. Most smooth-bore shotguns have rifled barrels, but some do not. Check the owner’s manual or ask the manufacturer to be sure.
The rifled slug can be an effective hunting and self-defense round, but it is not without its limitations. The smooth-bore shotgun is not as accurate as a rifle and the pattern will be wider at long range. The slug is also less effective against armor.
If you choose to use a rifled slug in a smooth-bore shotgun, be sure to use the proper ammunition and understand the limitations of your firearm.

Smooth Bore Shotgun vs Rifled Bore
When it comes to shotguns, there are two main types of barrels – smooth bore and rifled. Each type has its own set of pros and cons, so it’s important to know the difference before choosing a shotgun for your needs.
Smooth Bore Shotguns
A smooth-bore shotgun has a barrel that is smooth on the inside. This type of barrel is best for shooting lead or steel shots, as the pellets will not spin when they are fired. This makes smooth-bore shotguns ideal for hunting game birds, as the pellets will spread out and increase the chances of hitting the target.
Smooth-bore shotguns are also typically cheaper than rifled barrels, as they are easier to manufacture. Additionally, smooth-bore barrels are typically lighter than rifled barrels, making them a good choice for those who plan on carrying their shotgun for long periods of time.
However, there are some disadvantages to using a smooth-bore shotgun. One is that the pellets will not be as accurate as they would be with a rifled barrel. Additionally, smooth-bore shotguns are not as effective at long range as rifled barrels.
Rifled Bore Shotguns
A rifled bore shotgun has a barrel that is grooved on the inside. This type of barrel is best for shooting slugs, as the grooves will cause the slug to spin as it is fired. This spin makes the slug more accurate, as it will not wobble as much in flight.
Rifled barrels are also a good choice for those who plan on shooting at long range, as the extra accuracy can be helpful. Additionally, rifled barrels can be used with sabot rounds, which are special rounds that have a plastic sleeve that helps them spin. This makes rifled barrels even more accurate than smooth-bore barrels.
However, there are some disadvantages to using a rifled barrel. One is that they are more expensive than smooth-bore barrels. Additionally, rifled barrels are typically heavier than smooth-bore barrels, making them a less ideal choice for those who plan on carrying their shotgun for long periods of time.
Frequently Asked Questions [FAQs]
Yes, you can shoot rifled slugs through a smooth-bore shotgun. Rifled slugs are designed to spin as they travel down the barrel, which stabilizes them in flight and makes them more accurate.
Rifled slugs are more accurate than traditional lead or buckshot, and they can also penetrate thicker targets.
Rifled slugs can damage the barrel of your shotgun over time, and they also produce more recoil than lead or buckshot.
You should clean your shotgun after every shooting session, whether you’re using rifled slugs or not. Rifled slugs can cause fouling in the barrel, which can lead to accuracy problems.
Rifled slugs should be stored in a cool, dry place. If they get wet, they can rust.
Conclusion
Rifled slugs can be shot through a smooth-bore shotgun, but the accuracy will be affected. The spin that the rifled slug imparts will be negated by the smooth bore of the shotgun, so the slug will not travel in a straight line. The best bet is to use a shotgun that is specifically designed for shooting slugs, such as a rifled slug gun.
