With the low burning speed of black powder, the best efficiency was achieved with large, heavy bullets, so the bullet was the largest practical diameter. The large diameter allowed a short, stable bullet with high weight, and the maximum practical bore volume to extract the most energy possible in a given length barrel. There were a few ...
Comparison of .577 Black Powder Express, .303 British & 8 bore bullets The most common 8 bore cartridges used paper cases, much like shotgun shells, and true .835 in (21.2 mm) caliber projectiles. A larger version utilising a thin brass case was also available, although it fired .875 in (22.2 mm) projectiles, in reality making it a 7 bore.
Burst barrel of a muzzle loader pistol replica, which was loaded with nitrocellulose powder instead of black powder and could not withstand the higher pressures of the modern propellant. The development of smokeless powders, such as cordite, in the late 19th century created the need for a spark-sensitive priming charge, such as gunpowder.
In some instances, the powder may not have even been fully burned in guns with short barrels. So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. Large naval guns will have high length-to-diameter ratios, ranging between 38:1 to 50:1. This length ...
The first black powder cartridge adopted in large numbers by the Japanese Army, it was used in the Murata rifle, a hybrid of French Gras and German Mausers 1871 and 1871/84 rifles. 12.7×108mm: 1930 USSR R 12.7×108mm 2700 11980 (13737) 255 0.511 108mm Used in Heavy Machine Guns, AT-rifles [41] and anti-materiel rifles. 14.5×114mm: 1941 [42 ...
A barrel that today costs $100 is the equivalent, in real dollars, to a $71 barrel in 2010 and a $56 barrel in 2000. ... But its energy imports are actually rising as the nation attempts to shift ...
In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder.

Ghanaian President Nana Akufo-Addo has broken ground on the construction of a 300,000 barrel-per-day oil refinery that the government hopes will turn the West African country into the region's ...
