1. A Brief Introduction to the .45-70 Government

The .45-70 Government cartridge has been around for over a century. It was originally developed for the U.S. military in the late 1800s, back when black powder was still the norm. Ever wonder why a cartridge that started in the days of the horse-drawn carriage can still be found on hunting trips and in shooters’ collections today? It’s simple: reliability, versatility, and sheer power.

You might say the .45-70 Government is like a wise old friend who never fails to show up when needed. Despite numerous modern cartridges on the market, the .45-70 still holds a special place in the hearts of hunters and firearm enthusiasts, largely due to its proven track record against big game and its ability to adapt to both old and new firearms.

2. History of the .45-70 Government

From Military Use to Civilian Favorite

The .45-70 Government was introduced in 1873 as the official cartridge for the “Trapdoor” Springfield rifle. At the time, it used a 405-grain bullet loaded with 70 grains of black powder—hence the name “.45-70.” This was an era where black powder, thick wood stocks, and single-shot rifles were standard. Soldiers found this cartridge incredibly effective, and it served well in various military engagements.

By the late 19th century, the .45-70 Government transitioned into civilian use. Hunters and frontiersmen recognized its stopping power for large game like buffalo, bear, and moose. Its popularity only grew from there. Despite more modern cartridges arriving in the early 20th century, this big-bore round remained a staple for those who needed something with a bit more oomph.

Adapting to Modern Smokeless Powder

As technology advanced, black powder gave way to smokeless powder, which offered higher velocities and reduced fouling. The .45-70 Government adapted seamlessly to these changes, allowing modern firearms to fire it at even greater speeds. This versatility proved key in helping it stay relevant in a fast-evolving firearms landscape. While the original black-powder load is still celebrated for its historical significance, current .45-70 ammo often employs modern powders, giving shooters the best of both worlds: heritage and performance.
