A spitzer bullet (from German: Spitzgeschoss, "point shot") is a munitions term, primarily regarding fully-powered and intermediate small-arms ammunition, describing bullets featuring an aerodynamically pointed nose shape, called a spire point, sometimes combined with a tapered base, called a boat tail (then a spitzer boat-tail bullet), in order to reduce drag and obtain a lower drag ...
A copper-plated hollow-point loaded in a .44 Magnum, for example, with an original weight of 240 grains (15.55 g) and a diameter of 0.43 inch (11 mm) might mushroom on impact to form a rough circle with a diameter of 0.70 inches (18 mm) and a final weight of 239 grains (15.48 g).
Projectile velocities can reach 4.5 kilometres per second (16,000 km/h) for the 8.0-inch (200 mm) configuration and 7 kilometres per second (25,000 km/h) for the 3.3-inch (84 mm) launcher configuration. [4] The primary use of the range facilities at Arnold Air Force Base is the measurement of released kinetic energy upon projectile impact.
Examples of various small-arms flechettes (scale in inches) A flechette or flèchette (/ f l eɪ ˈ ʃ ɛ t / fle-SHET) is a pointed, fin-stabilized steel projectile.The name comes from French flèchette (from \flèche), meaning "little arrow" or "dart", and sometimes retains the grave accent in English: flèchette.
Alternatively if released at high altitudes over 10,000 feet (3,000 m), the projectile will approach its terminal velocity of around 700 feet per second (210 m/s; 480 mph; 770 km/h). [6] [2] A variant version of the "Lazy Dog" projectile was developed for the recoilless rifle. Development was suspended because another type of flechette was used ...
It has an effective range of 75 m to 5000 m, and takes 17.6 seconds to reach maximum range. Refleks can penetrate about 900 millimetres (35 in) of steel armour and can engage low-flying air targets such as helicopters. [14] Country of origin: Soviet Union; Projectile weight: 16.5 kg; Warhead weight: 4.5 kg; Guidance system: Laser beam riding
The 62 grain (4.0 g) projectile can better penetrate steel, brick, concrete, and masonry walls, as well as body armor and sheet metal. It penetrates 3 ⁄ 8 in (9.5 mm) of mild steel at 350 meters, which the M855 can only do at 160 meters.
High-explosive anti-tank (HEAT) – Can penetrate up to 45 centimetres (18 in) of rolled homogeneous armour (RHA) with beyond-armour effect. [21] High-explosive dual purpose (HEDP) 502 [5] [22] – For use against bunkers, buildings, enemy personnel in the open, and light armour. It can be set to detonate on impact or with a brief detonation delay.
