We’ll explore its history, ballistics, common uses, and potential modifications. Understanding the 45-70 lever action will equip you to make an informed decision about whether this powerful classic is right for you.
The Legacy of the .45-70 Government Cartridge
The .45-70 Government cartridge itself is a significant part of the story. Adopted by the U.S. Army in 1873, this powerful round was originally designed for the Trapdoor Springfield rifle. Its massive bullet, typically weighing between 300 and 500 grains, delivers substantial stopping power at close to medium ranges. This cartridge has seen extensive use throughout history, participating in conflicts from the Indian Wars to the Spanish-American War. Its enduring popularity speaks to its effectiveness and the enduring legacy of the cartridge itself. The stopping power, even by today's standards, is remarkable.
Evolution of the 45-70 Lever Action
While originally chambered in single-shot breech-loading rifles, the .45-70 cartridge found a new home in lever-action rifles, significantly increasing its practical rate of fire. Manufacturers like Marlin and Winchester quickly adopted the cartridge, producing iconic lever-action rifles that cemented the .45-70's place in American history. Modern lever-action rifles chambered in .45-70 often feature improved actions, stronger receivers, and enhanced safety features compared to their historical counterparts. The ability to quickly cycle through rounds makes these firearms suitable for various applications, from hunting large game to defensive purposes.
Ballistics and Performance: Why it's a "Thumper"
The term "thumper" accurately describes the .45-70's recoil and impact. The substantial bullet weight, coupled with relatively low velocities (compared to modern high-velocity cartridges), delivers impressive energy transfer upon impact. This makes it highly effective for hunting large game.
| Bullet Weight (grains) | Muzzle Velocity (fps) | Muzzle Energy (ft-lbs) |
|---|---|---|
| 300 | 1800 | 2500 |
| 405 | 1600 | 3000 |
| 500 | 1300 | 3000 |
Note: These are approximate values and can vary based on ammunition manufacturer, barrel length, and other factors.
The lower velocity, while seeming less potent than modern cartridges, contributes to better bullet expansion and penetration within the target, delivering greater stopping power.
Applications and Uses of the 45-70 Lever Action
The 45-70 lever action is surprisingly versatile:
-
Big Game Hunting: This is the primary application. Elk, moose, bear, and deer are all well within its capabilities. The significant stopping power ensures quick, humane kills.
