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]
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.
Shotguns have an effective range of about 35 m (38 yd) with buckshot, 45 m (49 yd) with birdshot, 100 m (110 yd) with slugs, and well over 150 m (160 yd) with saboted slugs in rifled barrels. [3] [4] [5] Most shotgun cartridges are designed to be fired from a smoothbore barrel, as "shot" would be spread too wide by rifling.
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.
An airgun slug is a new [when?} type of pellet recently developed for pre-charged pneumatic airguns. Unlike the conventional diabolo -shaped pellet, which is aerodynamically poor and relies heavily on drag -stabilisation to maintain accuracy, the slug pellet is cylindro-conoidally shaped like a Minié ball and relies predominantly on spin ...
Second-generation Chinese sabot round introduced in 1999. Initially 125-IIM acted as the export version with reduced velocity but with the introduction of DTC10-125, the DTW-125 itself became exported under the name “BTA4” Country of origin: China; Projectile dimension: 642 mm; Round weight: 21.36 kg; Projectile weight (without Sabot): 4.1kg
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
Shotgun slugs are currently under consideration by the US military as an anti-materiel round; the tendency of typical commercial shotgun slugs to deform on impact would render them illegal under the Hague Convention of 1899 and so a jacketed, hardened or sabot slug may be adopted. Less lethal rounds are used by U.S. troops serving as police ...
