Armour-piercing discarding sabot higher muzzle velocity. Unfortunately the low sectional density of the APCR resulted in poor carrying power (high aerodynamic drag), losing velocity and penetration rapidly over distance. To overcome these limitations the British devised a way for the outer sheath to be discarded after leaving the bore. The name given to the discarded outer sheath was the sabot (a French word for a wooden shoe). For APDS projectiles the sabot is also known as a pot, as the sabot resembles a flower pot in shape. The APDS has the advantages of the lightweight projectile with regards to bore acceleration and high
Armour-piercing discarding sabot Armour-piercing discarding sabot Armour-piercing discarding sabot (APDS) is a type of kinetic energy projectile fired from a rifled-barrel gun to attack armoured targets. APDS rounds are sabot rounds, firing a spin-stabilized armor penetrating sub-projectile, and were commonly used in large calibre tank guns, up until the early 1980s, but have now been superseded by armour-piercing, fin-stabilised, discarding sabot (APFSDS) projectiles used in smooth-bore guns, firing a fin-stabilized armor penetrating sub-projectile. However, APDS rounds are still commonly used in small or medium calibre weapon systems. For a given calibre, this type of ammunition can effectively double the armour penetration of a
