This specific cartridge designates a .45-70 Government round loaded with a 405-grain lead bullet. The .45-70 Government, a centerfire rifle cartridge, was developed in 1873 for the U.S. Army’s Springfield Trapdoor rifle. This particular loading, using a heavy lead projectile, represents a classic configuration often favored by hunters and enthusiasts of historical firearms.
Historically, this combination provided substantial stopping power for large game like bison and elk, contributing significantly to westward expansion. Today, it remains a popular choice among modern hunters pursuing similar game and among those who enjoy the challenge and historical significance of shooting vintage firearms. Its enduring popularity stems from its effectiveness at moderate ranges and the readily available ammunition and reloading components.
