Also the muzzle energy is only an upper limit for how much energy is transmitted to the target, and the effects of a ballistic trauma depend on several other factors as well. There is wide variation in commercial ammunition. A 180 gr (12 g) bullet fired from .357 Magnum handgun can achieve a muzzle energy of 580 ft⋅lbf (790 J). A 110 gr (7.1 ...
These factors, along with Taylor’s dismissal of muzzle energy, allow many obsolete low powered large bore cartridges such as the .577/450 Martini-Henry and the .45-70 Government to have as much as twice the TKOF than the smaller bore general purpose hunting cartridges such as the .303 British and the .30-06 Springfield. For these reasons the ...
Diagram of .45 Colt U.S. Army "ball cartridge" for Army M1909 revolver, with dimensions in inches. The .45 Colt was a joint development between Colt's Patent Firearms Manufacturing Company (now known as Colt's Manufacturing Company), of Hartford, Connecticut, and the Union Metallic Cartridge Company (UMC) of Bridgeport, Connecticut.
See: .45-70 at Two Miles: The Sandy Hook Tests of 1879), a new variation of the .45-70 cartridge was produced: the .45-70-500, which fired a heavier, 500-grain (32 g) bullet. The heavier bullet produced significantly superior ballistics and could reach ranges of 3,350 yd (3,060 m), which were beyond the maximum range of the .45-70-405.
The .450 Marlin is a firearms cartridge designed as a modernized equivalent to the .45-70 cartridge. It was designed by a joint team of Marlin and Hornady engineers headed by Hornady's Mitch Mittelstaedt, [4] and was released in 2000, with cartridges manufactured by Hornady and rifles manufactured by Marlin, mainly the Model 1895M levergun.
The .460 S&W Magnum was derived from the .454 Casull while the .454 Casull was derived from the .45 Colt. Because of this lineage the .460 S&W Magnum has similar dimensional attributes to the .45 Colt with the exception of a much longer casing. As such, revolvers chambered to .460 S&W Magnum will usually chamber the shorter .45 Colt.
In cartridges surviving from the black-powder era (examples being .45 Colt, .45-70 Government), the case is much larger than is needed to hold the maximum charge of high-density smokeless powder. This extra room allows the powder to shift in the case, piling up near the front or back of the case and potentially causing significant variations in ...
The ballistic coefficient of an atmospheric reentry vehicle has a significant effect on its behavior. A very high ballistic coefficient vehicle would lose velocity very slowly and would impact the Earth's surface at higher speeds. In contrast, a low ballistic coefficient vehicle would reach subsonic speeds before reaching the ground. [75]
