The H&R design loaded the dart from the XM144 into their own cartridge design. The H&R design was the most advanced. It mounted the dart between three plastic sabots in a triangular plastic cartridge. When fired, the sabots were discarded early in small "sub-barrels" while the dart continued down the main barrel.
Armour-piercing fin-stabilized discarding sabot (APFSDS), long dart penetrator, or simply dart ammunition is a type of kinetic energy penetrator ammunition used to attack modern vehicle armour. As an armament for main battle tanks , it succeeds armour-piercing discarding sabot (APDS) ammunition, which is still used in small or medium caliber ...
Darts is a competitive sport in which two or more players bare-handedly throw small sharp-pointed projectiles known as darts at a round target known as a dartboard. [2]Points can be scored by hitting specific marked areas of the board, though unlike in sports such as archery, these areas are distributed all across the board and do not follow a principle of points increasing toward the board's ...
The ACR "rifles" used smoothbore barrels to fire single or multiple flechettes (tiny darts), rather than bullets, per pull of the trigger, to provide long range, flat trajectory, and armor-piercing abilities. Just like kinetic-energy tank rounds, flechettes are too long and thin to be stabilized by rifling and perform best from a smoothbore barrel.
The M829 dart has a ballistic nose and six tail fins made of aluminum. It is carried in the gun tube by a four-piece aluminum sabot, which separates into four "petals" soon after the round leaves the gun tube. [2] The propulsion system uses an obturating case base with a semi-combustible cartridge wall.
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.
