According to Tang Shunzhi, writing in the mid-1500s, the cost of production for a musket required 0.2 taels for 20 catties of Fujian iron, 0.18 taels for 6 days of work to hammer out the iron, 0.19 taels for 6 days of work forging the iron into a tube, 0.21 taels for 7 days of work boring the barrel, and other miscellaneous costs such as 0.01 ...
The KAC PDW fires a 6×35 mm cartridge, which is over a centimeter shorter than the 5.56×45mm NATO round. The 6mm bullet is slightly wider, and the standard 6×35mm bullet slightly heavier, than the standard 5.56mm bullet (65 grains (4.2 g) versus 62 grains (4.0 g)).
Iron Beam is an air defense system in development by Israeli defense contractor Rafael Advanced Defense Systems. [8] Unveiled at the 2014 Singapore Air Show on 11 February, [9] the system is designed to destroy short-range rockets, artillery, and mortars with a range of up to 7 km (4.3 mi), too small for the Iron Dome system to intercept ...
A mine shell (from German: Minengeschoss, "mine shot") or high-explosive, high-capacity (HEHC) [a] in British military nomenclature, [1] [2] [3] is a military explosive shell type characterized by thin (usually steel) shell walls and a correspondingly high quantity of explosives, much higher than the traditional high-explosive shell type per caliber, meaning that mine shells trade ...
Casemates on the main deck were very close to the waterline. In the Edgar-class cruisers, the guns in the casemates were only 10 feet (3.0 m) above the waterline. [35] Casemates that were too close to the waterline or too close to the bow (such as in the 1912 Iron Duke-class dreadnoughts) were prone to flooding, making the guns ineffective. [36]
The Minié ball is a cylindro-conoidal bullet with grease-filled cannelures on its exterior and a cone-shaped hollow in its base.Minié designed the bullet with a small iron plug, and lead skirting that would expand under the pressure of gunpowder deflagration causing the bullet to obturate, and grip the rifling grooves.
The Maschinengewehr (MG) 151 is a belt-fed autocannon for aircraft use, developed in Nazi Germany from 1934 to 1940 and produced by Waffenfabrik Mauser during World War II.It was originally produced in 15.1 mm caliber from 1940, with a 15×96mm cartridge, but due to demand for higher effect against aircraft, especially with the introduction of mine shells for the 20 mm MG-FF/M aircraft cannon ...
However, the ammo was much heavier (393 gr (25.4 g) for 7.62 x 51 round compared to 160 gr (10.4 g) for .45 ACP), effectively limiting the ammo load. Additionally, when fired in full automatic mode free recoil delivered by full-sized and full-powered cartridges became an issue, too.
