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 ...
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
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.
For comparison, Hornady's 9249 load for the .500 S&W Magnum cartridge offers slightly less energy at the muzzle, achieving 2,868 ft⋅lbf (3,888 J) by driving a 300 grain (19 g) FTX bullet at 2,075 ft/s (632 m/s). Buffalo Bore's loading for the .500 S&W cartridge offers much less energy at the muzzle, achieving only 2,579 ft⋅lbf (3,497 J) by ...
Dug out my internal ballistics software and plugged in the .45-70-405 data based on the Sandy Hook trials and a .308 long range load, and got the following: The scale exagerates the slope a bit--the .45-70 is actually traveling downwards at about a 20 degree angle when it hits--but the .308 is only doing about a 3.6 degree angle.
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.
