An APFSDS separating from its spindle sabot
 Anti-tank round with its sabot A sabot (pronounced "say-boh") refers to a device named for a shoe used in a firearm or cannon to fire a projectile, such as a bullet, that is smaller than the bore diameter. Since a strong seal is needed to trap propellant gasses behind the projectile, and keep the projectile centered in the barrel, something is needed to fill the gap between projectile and barrel, which is the role of the sabot. Firing a small size projectile wrapped in a sabot raises the muzzle velocity of the projectile. Made of some lightweight material (usually plastic in smallbore guns, and aluminium - and, in earlier times, wood - in cannon), the sabot usually consists of several pieces held in place by the cartridge or a loose connection. When the projectile is fired, the sabot blocks the gas, and accelerates the projectile down the barrel. When the sabot reaches the end of the barrel, the shock of hitting still air pulls the parts of the sabot away from the projectile, allowing the projectile to continue in flight.

Sabots are used to fire the flechettes that form anti-armour kinetic energy penetrators. The word flechette is French and means dart (literally, little arrow). It is a projectile having the form of a small metal dart, usually steel, with a sharp-pointed tip and a tail with several vanes to stabilize it during flight. ...

Sabot-type shotgun slugs were marketed in the U.S. starting in about 1985. When used with a rifled slug barrel, they offer vastly improved accuracy compared to traditional shotgun slugs. They are now legal for hunting in most states. Rifling is the means by which a firearm gyroscopically stabilizes a projectile. ...

The name "sabot" comes from wooden shoes traditionally worn in some European countries, called clogs. The word is of French origin. The word sabotage was supposedly derived from sabot, as people would drop these wooden shoes into machinery when displeased with the conditions of their employment in order to stop production. The word clog, as applied to footwear, has these meanings:- A type of shoe or sandal made predominantly out of wood. ...

Cup sabot A cup sabot merely supports the base and rear end of a projectile. When the sabot and projectile exit the muzzle of the gun, air pressure on the sabot forces the sabot to release the projectile.
Expanding cup sabot Used typically in small arms (most commonly muzzleloaders), an expanding cup sabot has a one piece sabot surrounding the base and sides of a projectile. Upon firing, when the sabot and projectile leave the muzzle of the gun, centrifugal force from the rotation of the projectile and sabot opens up the segments surrounding the projectile, releasing it. A US soldier drops a shell into the muzzle of an M224 60-mm mortar. ...
Base sabot A base sabot has a one piece base which supports the bottom of the projectile, and separate pieces that surround the sides of the projectile and center it.
The base sabot has better and cleaner sabot/projectile separation than cup or expanding cup sabots, but is more expensive since more pieces are involved.
Spindle sabot A spindle sabot uses a set (usually two) of matched rings which have a center section in contact with a long projectile, front sections which center that projectile in the barrel, and a rear section which both centers the projectile and seals propellant gases.
Spindle sabots are the standard western type armor piercing ammunition type. Two and three piece spindle type sabots are shown in the illustrations at the top of this article.
Shotgun slugs often use a cast plastic sabot similar to the spindle sabot. Shotgun sabots in general extend the full length of the projectile and are designed to be used in rifled barrels. A shotgun slug is a single projectile designed to be fired out of a shotgun. ...

Ring sabot
 Soviet BM-15 Armor piercing round with ring sabot A ring sabot uses the rear fins on a long projectile to help center the projectile, and the multi-piece sabot forms only a single thin ring around the projectile near the front, sealing gases from escaping past it and centering the front of the projectile.

Because the rear fins have to have the same diameter as the gun bore, they typically are larger than is optimum for flight performance.
Several Soviet and current Russian design armor piercing sabot projectiles use ring sabots.
