Swedish "37/24 mm slpprj m/49" APDS projectile for the Bofors 37 mm anti-tank gun from 1949. 37/24 indicates full-calibre with sabot and sub-caliber without sabot — 37 / 24 mm (1.46 / 0.945 in). Left object shows the projectile with sabot, central object shows projectile without sabot and the right object is the projectile's tungsten-core.
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.
Armour-piercing fin-stabilized discarding sabot (APFSDS) in English nomenclature, alternatively called "arrow projectile" or "dart projectile" (German: Pfeil-Geschoss, Swedish: pilprojektil, Norwegian: pilprosjektil), is a saboted sub-calibre high-sectional density projectile, typically known as a long rod penetrator (LRP), which has been ...
Sub-caliber armour-piercing discarding sabot projectile. Here seen with and without its sabot as well as its internal tungsten core. The most traditional way to fire sub-caliber ammunition is to fit the projectile with an expendable sabot. The sabot is a device which fills out the missing caliber when the projectile is fired and then leaves the ...
Maintaining the in-bore structural integrity of such a long flight projectile under accelerations of tens of thousands of g's is not a trivial undertaking, and has brought the design of sabots from employing in the early 1980s readily available low cost, high strength aerospace-grade aluminums, such as 6061 and 6066-T6, to high strength and ...
Projectile weight (including sabot): 5.9 kg; Projectile weight: 3.9 kg including 2.9 kg and 0.27 kg tungsten carbide plug; Muzzle velocity: 1785 m/s; Muzzle energy: 6.2 MJ; Penetration: 400 mm at 0° at 2000 m, 150 mm at 60° at 2000 m
The projectile used by the 6.5×25mm CBJ can be a normal ball bullet, but can also be a 4 mm tungsten kinetic penetrator held inside a non-disintegrating plastic sabot, fired at a high muzzle velocity of 815 m/s (2,670 ft/s) with the ability to defeat most contemporary body armours.
The SLAP design incorporates a polymer sabot, which allows for the use of a tungsten penetrator projectile of a lesser diameter than the original bore.By using the casing of a large cartridge with a lightweight projectile, the velocity of the projectile is greatly increased and the sectional density is improved without requiring a (potentially dangerous) increase in chamber pressure.
