It has a long heavy bullet with a semi-armor-piercing iron or mild steel core and a gilded steel jacket. After the Vietnam War it was replaced by the M80 ball cartridge as the standard round. Data contained in TM 9-1005-298-12 mentions the approximate maximum range of 3,820-metre (4,180 yd) at 856.2-metre-per-second (2,809 ft/s) muzzle velocity.
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
It can penetrate a 6 mm (0.2 in) thick St3 steel plate at 300 m (328 yd) and 6Zh85T body armour at 30 m (33 yd). [citation needed] The 7N23 armour-piercing bullet, introduced in 2002, has a 3.6 g (55.6 gr) sharp-pointed steel penetrator made of steel U12A and retains the soft lead plug in the nose for jacket discarding. The bullet has a black tip.
"Grain foot per second" (gr·ft/s) can be obtained by measuring the mass in grains (gr) (7,000 to the pound) and velocity in feet per second (ft/s), but since their product yields a very large number it is common to multiply by a factor of 1 ⁄ 1000, obtaining the power factor in kilo grain foot per second instead.
The DBP10 cartridge was developed in 2010 and has a hardened steel-cored 4.6 grams (71 gr) bullet, a muzzle velocity of 915 metres per second (3,002 ft/s) from a standard barrel (Type 95 / QBZ-95, 463 mm barrel length) and was designed to match nine different then serving 5.8×42mm chambered weapons. These weapons featured different barrel ...
The SS109 used a 62 gr full metal jacket bullet with a seven grain mild steel tip to move the center of gravity rearward, increasing flight stability and thereby the chances of striking the target tip-first at longer ranges, in part to meet a requirement that the bullet be able to penetrate through one side of a WWII U.S. M1 helmet at 500 yd ...
Michael Crumling, a 25-year-old machinist, recently designed bullets that use a rather thick, steel shell, strong enough to keep a hold of the blast from inside without spreading any force to the ...
.950 JDJ cases are approximately 70 mm in length, and are based on a 20×102mm Vulcan case shortened and necked up to accept the .950 in (24.1 mm) bullet. Projectiles are custom-made and most commonly weigh 3,600 grains (230 g) which is 8.2 ounces or over half a pound.
