Savor slugs are designed to be shot through a rifled slug barrel, not a smooth bore. Without the rifling in the barrel, there is nothing to impart spin and stabilize the projectile.

They can, you’ll get your best accuracy if shot through an improved cylinder or mod choke. Don’t expect MOA accuracy though, you only have a front bead to work with. Minute of deer at 50yds is attainable. YMMV

There are two primary types of shotgun slugs …. one is a rifled slug which is intended for smooth bore shotguns, preferably with a "cylinder" choke. The other type is a smooth sided slug intended for barrel with rifling. It's never a good idea to use a smooth slug in a smooth bore or a rifled slug in a rifled bore. Not only will accuracy suffer, a smooth side slug can blow the choke out of a smooth bore barrel.

As far as I know, all slugs for shotguns are spin stabilized and will usually maintain stability for at least 100 yards. I never heard of "drag stabilized". Maybe that's what arrows or rockets with fins use???

I put a document in the forum E-Library titled "Shotgun Chokes and Related Issues". Slugs are also covered so you might want to take a few minutes to read the article. Here's a link: https://rugerforum.net/e-library/838...ed-issues.html

And don’t bother trying those rifled choke tubes. They don’t work for squat.

My buddy's son shot these 2 pigs at about 80 yards with my 12 gauge Rem 870. 22 Hastings rifled barrel with iron sights. Federal trophy copper 3 sabots. Needless to say, no tracking was required. The short 18 rifled barrel from Remington was not long enough to stabilize the sabots at 50+ yards (erratic groups and keyholing), so I went with the 22 and its very accurate for a shotgun.

I have a 20" slug barrel, cylinder bore, non-rifled. Drag stabilized would be like an arrow or tank round. I didn't know how sabot slugs were stabilized. That is why I asked. Thanks for the information.

I found a couple references for "drag stabilization". Some examples are a rocket with fins, or an arrow with feather flights. I also found a reference for shotgun bean bags that use a tail much like a kite. The concept being …. air friction (drag) keeps the object moving in a predictable direction. BTW, a tank gun barrel has rifling and is similar to a hunting rifle on steroids.

Rifled slugs get some of their spin from the impeller type surface. Most of the slug's spin happens in the bore but as air moves past the slug in flight, it will make the slug continue to spin. I guess you could say it is somewhat "drag stabilized". Smooth sided sabots require a barrel with rifling to spin the slug and stabilize it as it travels down range. In a smooth bore, it with get unstable very early in flight and start tumbling …. then there goes the neighborhood as far as accuracy is concerned.

Sabots need to be spun so they can open consistently after leaving the muzzle.
