About the 45-70 Cartridge
The .45-70 rifle cartridge, also known as . 45-70 Government, was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873, which is known to collectors as the "Trapdoor Springfield". The new cartridge was a replacement for the stop-gap .50-70 Government cartridge which had been adopted in 1866, one year after the end of the American Civil War.

The new cartridge was completely identified as the .45-70-405, but was also referred to as the ".45 Government" cartridge in commercial catalogs. The nomenclature of the time was based on three properties of the cartridge:
.45: nominal diameter of bullet, measured in decimal inches, i.e., 0.458 inches (11.63 mm);
70: weight of black powder, measured in grains, i.e., 70 grains (4.56 g);
405: weight of lead bullet, measured in grains, i.e., 405 grains (26.2 g).
