A Glimpse into the Past: Echoes of the Old West
The .45 Colt
The history of the American West is etched in steel, gunpowder, and the relentless pursuit of the horizon. Among the firearms that shaped this era, and continue to resonate with shooters today, are two iconic cartridges: the .45 Colt and the .45-70. These rounds, though sharing a common ancestry and a similar bullet diameter, represent very different approaches to projectile delivery. Exploring their capabilities, history, and suitability for various tasks reveals a fascinating tale of ballistics, firearm design, and the enduring appeal of these classic cartridges. This comparison aims to delve deep into the specifics of these two legends, helping shooters understand their strengths, weaknesses, and which cartridge best aligns with their needs.
The .45-70 Government
In contrast, the .45-70 Government (or simply .45-70) was born from the need for a more powerful cartridge to equip the US military. Developed for the Springfield Model 1873 rifle, it addressed the need for greater range and stopping power against both adversaries and large game. The .45-70, with its heavier bullet and larger powder charge, was a significant leap in cartridge design. The .45-70 quickly became a favorite among hunters and frontiersmen seeking to take down larger game such as bison, elk, and bear. Its impressive performance at longer ranges established its place as a staple of the American frontier. The rifle itself, along with its cartridge, shaped battles and hunting expeditions throughout the territories.
Understanding the Numbers: Cartridge Specifications and Differences
.45 Colt Specifications
A closer examination of the specifications of these two cartridges reveals the fundamental differences in their design and capabilities. The .45 Colt and .45-70 share a bullet diameter, which is .452 inches, but their dimensions, powder capacities, and resulting performance differ significantly. These key aspects dictate the effective range and impact each round has on its target.
.45-70 Specifications
The .45 Colt is often considered a relatively compact cartridge. Its case length is typically around 1.3 inches. This allows for the chambering in handguns and rifles, while also limiting the amount of propellant that can be used. Bullet weights generally range from around 200 to 255 grains, depending on the load. Muzzle velocities vary depending on the firearm and specific load, but typically fall between 700 and 1,000 feet per second (fps). The energy produced by the .45 Colt is more modest, usually in the range of 300 to 550 foot-pounds at the muzzle. This makes it suitable for close range work and target shooting. The smaller size gives .45 Colt guns advantages in weight and maneuverability.
Comparative Analysis
The .45-70, on the other hand, is a much larger cartridge, reflecting its designed role in the military and for big game hunting. Its case length is about 2.1 inches, holding a substantially larger volume of powder. Bullet weights are significantly heavier, typically ranging from 300 to 500 grains, with heavier bullets being more common for hunting. Muzzle velocities vary widely depending on the load but can reach up to 1,800 fps for some modern loads. The resulting energy is considerably higher, often exceeding 1,500 foot-pounds at the muzzle. This increased power makes the .45-70 a formidable cartridge for taking down larger game at longer distances. Its design made it ideal for battles, allowing soldiers to fire further and more accurately.
Performance on the Range and in the Field: Ballistic Capabilities
.45 Colt Ballistics
Ballistics is the science of projectiles in motion. Understanding the ballistic characteristics of the .45 Colt and .45-70 is essential to accurately assessing their capabilities for various applications.
.45-70 Ballistics
The .45 Colt, designed primarily for handguns, typically excels at shorter ranges. Its effective range in a revolver is generally considered to be within 50 yards, although accurate shooters can extend this range somewhat. The trajectory of the bullet is relatively flat over short distances, but it begins to arc noticeably beyond that point. Bullet drop is a factor, but less pronounced when compared to the .45-70. The .45 Colt provides adequate power for self-defense, target shooting, and plinking. While it can be used for hunting, its limited energy makes it best suited for smaller game at close range. The lighter recoil of .45 Colt makes it easier to control and it is a popular round in Cowboy Action Shooting.
Recoil Considerations
The .45-70, built for rifles, boasts significantly greater range and power. The effective range of the .45-70 can extend well beyond 200 yards, with some hunters confidently engaging targets at 300 yards or more. The trajectory, though flatter than the .45 Colt at longer ranges, is still subject to significant bullet drop. This requires the shooter to carefully estimate the distance to the target and adjust their aim accordingly. The .45-70 delivers a substantial impact, making it effective for hunting larger game, where its heavy bullet and high energy transfer deliver the necessary knock-down power. Hunting applications require the user to understand the bullet drop to get an accurate shot.
The Tools of the Trade: Firearms for Each Cartridge

The .45 Colt and .45-70 are not limited to a single firearm platform. Their flexibility and the availability of different designs for each cartridge further expands their appeal.
Firearms for .45-70
The .45 Colt has a strong connection to revolvers. The Colt Single Action Army, the original firearm for the round, remains a popular choice for both historical enthusiasts and Cowboy Action Shooters. Modern manufacturers continue to produce a wide variety of .45 Colt revolvers, including double-action revolvers and models with adjustable sights. Lever-action rifles are also chambered in .45 Colt, which extends the effective range and enhances the cartridge’s capabilities. These lever-action rifles are favored for their quick handling and the classic appeal of the round.
Comparing Firearms
The .45-70 is predominantly a rifle cartridge. Lever-action rifles, especially those made by Marlin and Winchester, are popular choices for hunting and recreational shooting. These rifles offer fast follow-up shots and a classic feel. Single-shot rifles, which were originally developed for the .45-70, are also still in production and are preferred for target shooting and long-range applications. Bolt-action rifles are less common for the .45-70, but they are available for shooters who prefer that platform. Bolt actions provide increased accuracy potential.
