A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.
The "Foster slug", invented by Karl M. Foster in 1931, and patented in 1947 (U.S. patent 2,414,863), is a type of shotgun slug designed to be fired through a smoothbore shotgun barrel, even though it commonly labeled as a "rifled" slug. A rifled slug is for smooth bores and a sabot slug is for rifled barrels. [9]
The M829 is an American armor-piercing fin-stabilized discarding sabot kinetic energy penetrator tank round.Modeling was done at the Ballistic Research Laboratory at Aberdeen Proving Ground, [1] which was incorporated into the Army Research Laboratory in 1992.
While some slugs are exactly that—a 12-gauge metal projectile in a cartridge—a sabot is a smaller but more aerodynamic projectile surrounded by a "shoe" of some other material. This "sabot" jacket seals the barrel, increasing pressure and acceleration, while also inducing spin on the projectile in a rifled barrel.
A rifled barrel will increase the accuracy of sabot slugs, but makes it unsuitable for firing shot, as it imparts a spin to the shot cup, causing the shot cluster to disperse. A rifled slug uses rifling on the slug itself so it can be used in a smoothbore shotgun.
Armor-piercing discarding sabot (APDS) is a type of spin-stabilized kinetic energy projectile for anti-armor warfare. Each projectile consists of a sub-caliber round fitted with a sabot . The combination of a lighter sub-caliber projectile with a full-caliber propellant charge allows for an increase in muzzle velocity compared to full-caliber ...
The short, fat, unaerodynamic Foster slug was no longer needed for its inherent stability; new slugs were smaller in diameter, usually around 10.16 to 12.7 millimeters (.40 to .50 caliber) (compared to the 18.5 millimeter (.73 inch) bore diameter of a 12 gauge), and carried in a plastic sabot. The saboted slug had half the frontal area of the ...
A slug is a term used for a bulky solid ballistic projectile. It is "solid" in the sense of being composed of one piece; the shape can vary widely, including partially hollowed shapes.
