In 1884, the US Ordnance Department increased the bullet weight of the 45–70 to 45–70–500, or a 45 caliber bullet, 70 grains of black powder, and a 500 grain bullet. [3] The new 45-70-500 loading was recorded with a muzzle velocity of 1315.7 feet, and generated 1525 ft lbs of energy at 100 yds, and 562.3 ft lbs of energy at 1,000 yards ...
The .50-70 Government cartridge used the Benét internal center-fire primer design and became the official cartridge of the U.S. military in 1866 until being replaced by the .45-70 Government in 1873. The .50-70 cartridge has a pressure limit of 22,500 psi (155 MPa) [1] The official designation of this cartridge at the time of introduction was ...
Swaging, rather than casting, became a preferred manufacturing technique during the 19th century Industrial Revolution; but cast bullets remained popular in early rimmed black powder cartridges like the .32-20 Winchester, .32-40 Ballard, .38-40 Winchester, .38-55 Winchester, .44-40 Winchester, .45 Colt, and .45-70.

In general, loads close to 100% density (or even loads where seating the bullet in the case compresses the powder) ignite and burn more consistently than lower-density loads. 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 ...
Boxes also recommended casting bullets from an alloy of one part tin and sixteen parts lead and lubricating bullets with Japan wax or tallow. [5] The .45-75 was shorter and fatter than the .45-70 government cartridge. Although the .45-75 was nominally superior to the popular .45-70, the weak toggle-link action with its elevator-style carrier ...
The 45-70-500 Government is an example. Often, the name reflects the company or individual who standardized it, such as the .30 Newton , or some characteristic important to that person. The .38 Special actually has a nominal bullet diameter of 0.3570 inches (9.07 mm) (jacketed) or 0.3580 inches (9.09 mm) (lead) while the case has a nominal ...
The Springfield Model 1884 had a muzzle velocity of 1315.7 feet per second with a 500 grain lead bullet. The muzzle velocity of the carbine bullet was 1,150 feet per second. The 1884 model rifle generated 1525 ft lbs of energy at 100 yds, and 562.3 ft lbs of energy at 1,000 yards, with a maximum range of 3,500 yards.
