Similarly to SLAP rounds (saboted light armor penetrator) which get their armor-piercing ability from the propulsion of a 7.62 mm tungsten heavy alloy bullet from a 12.7 mm barrel (.50 caliber) using a sabot with much more energy than is usually possible from a 7.62 mm round, HEIAP munitions utilize a similar theory with an added explosive ...
It consists of a sub-caliber 0.224-inch (5.7 mm) diameter bullet, held in a .30-caliber 7-grain (0.45 g) six-fingered plastic sabot with a hollowed base. The bullet separates from the sabot approximately 14 inches (360 mm) from the muzzle.
At 2,400 m (2,625 yd) the total drop predictions deviate 47.5 cm (19.7 in) or 0.20 mil (0.68 moa) at 50° latitude and up to 2,700 m (2,953 yd) the total drop predictions are within 0.30 mil (1 moa) at 50° latitude. The 2016 Lapua Ballistics 6 DoF App version predictions were even closer to the Doppler radar test predictions.
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
Named after CBJ Tech AB's founder and president Carl Bertil Johansson, [3] the 6.5×25mm CBJ has the same functional dimensions as the 9×19mm Parabellum and was designed to produce the same recoil and pressures to allow most 9 mm caliber weapons to be converted to 6.5×25mm CBJ with a simple barrel change. Also, because the 6.5×25mm CBJ has ...
As a result, the twist rate of the larger barrel will dictate which smaller bullets can be fired with sufficient stability out of a sabot. In this example, using 1:10 rifling in 7.62mm restricts saboting to 5.56mm bullets that require 1:10 twist or slower, and this requirement will tend to restrict saboting to the shorter (and lighter) 5.56mm ...
Projectile dimension: 435 mm 12: 1 L/d; 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 M829A3 round has a total mass of 22.3 kg (49 lb) and length of 892 mm (35.1 in). It uses 8.1 kg (18 lb) of RPD-380 stick propellant, accelerating the 10 kg (22 lb) sabot and depleted-uranium rod penetrator assembly, and a muzzle velocity of 1,555 m/s (5,100 ft/s). [ 7 ]
