The story of the 45-70 and the 45 Colt begins in a time of rapid innovation and westward expansion. Their origins, deeply intertwined with the U.S. military and the burgeoning firearms industry, shaped their destinies.
The 45-70 Government, officially known as the 45-70 (a designation derived from the cartridge’s bullet diameter of .45 inches, the weight of the black powder charge in grains, and the weight of the bullet in grains), emerged in the late 1800s. It was developed as the standard-issue cartridge for the U.S. Army, specifically for the Springfield Model 1873 “Trapdoor” rifle. The military sought a powerful cartridge capable of delivering devastating stopping power at extended ranges. The 45-70 fulfilled this requirement admirably. The cartridge was instrumental in the Indian Wars and served soldiers for several decades. Its robust design and high-powered performance quickly gained a reputation. The 45-70, as the standard issue, became synonymous with the U.S. military in the late 19th century, and its influence was immediately felt, helping to shape the firearms industry and the American frontier. Its use continued far beyond its primary military purpose, finding favor in hunting, target shooting, and even civilian defense, solidifying its legacy.
45 Colt
The 45 Colt, on the other hand, took a different route, born from the innovative mind of Samuel Colt and manufactured by his famed Colt’s Patent Firearms Manufacturing Company. Introduced around the same time as the 45-70, the 45 Colt was initially designed for use in the Colt Single Action Army revolver, also known as the “Peacemaker,” or “Frontier Six-Shooter.” This revolver quickly became a symbol of the American West, carried by lawmen, cowboys, and outlaws alike. The 45 Colt was adopted not only by the U.S. Army but also by civilians, earning a place in history as a favored cartridge of the period. The 45 Colt was more than just a cartridge; it was an extension of the iconic revolver. It offered a balance of power and manageability that made it a favorite for personal defense, hunting, and general use. The 45 Colt is deeply woven into the fabric of Western pop culture, a symbol of self-reliance and the spirit of the American frontier.
Understanding the Core: Cartridge Specifications and Design
To fully grasp the differences between the 45-70 and the 45 Colt, it’s essential to understand the technical specifications of each cartridge. These seemingly minor details have significant implications for performance and functionality.
45-70
The 45-70 boasts a much larger physical presence than the 45 Colt. Its case is significantly longer, allowing for a greater powder capacity. Its dimensions create a bullet that is inherently powerful, capable of launching heavier bullets at impressive velocities. The 45-70 typically uses bullets ranging from approximately 300 to over 500 grains in weight, providing exceptional energy at impact. The generous powder capacity of the 45-70 allows for various loading styles. Traditional black powder loads are still prevalent, and they offer a classic shooting experience, complete with a puff of smoke. Modern smokeless powder loads have also been developed, offering even greater performance potential, extending the range and overall versatility of the cartridge. The design of the 45-70 is specifically optimized for use in rifles, with a rifling twist rate suited for longer bullets, giving them stability at long distances.
45 Colt
The 45 Colt, in contrast, features a shorter and sleeker profile. Designed for a revolver, its case dimensions are naturally more compact. This compactness facilitates ease of use and allows for a more manageable recoil impulse. The 45 Colt typically launches bullets in the 230 to 255-grain range, which offers a good balance between power and control in the handgun, for which it was designed. The lower powder capacity contributes to a moderate recoil, making the 45 Colt more accessible to shooters of all experience levels. Its versatility is a key advantage. The bullet’s design is typically optimized for revolvers, though rifles have also been made for this caliber.
A critical design feature impacting performance is the rim size. The 45-70 has a rim diameter that is smaller than the diameter of the cartridge case, allowing it to feed smoothly from magazine-fed rifles. The 45 Colt has a larger rim, which is ideal for revolvers where the rim is used to extract the spent cartridge.
The Numbers Tell the Story: Ballistics and Performance
The ballistic performance of a cartridge refers to its trajectory, velocity, and energy delivered upon impact. These factors, directly related to the cartridge’s design and specifications, will tell the story of the 45-70 and 45 Colt.
45-70
The 45-70 is renowned for its impressive power and extended range. With appropriate loads, the 45-70 can generate muzzle velocities exceeding 1,800 feet per second (fps) with significant muzzle energy, often exceeding 2,500 foot-pounds (ft-lbs). Its trajectory, while relatively flat at shorter ranges, exhibits considerable bullet drop at longer distances. This makes it a formidable choice for hunting big game, such as bear, elk, and moose, at distances where accuracy and power are paramount. The effective range of a 45-70 rifle, with a skilled shooter and appropriate optics, can easily reach out to 400 yards or beyond, though proper compensation for bullet drop is essential.
45 Colt
The 45 Colt excels in the realm of handguns, showcasing respectable performance for its size. Modern loads may achieve muzzle velocities of around 800 to 1,000 fps, with muzzle energy in the 350 to 450 ft-lbs range. Its trajectory is typically flatter than the 45-70 at shorter distances, making it well-suited for close-range encounters and target practice. The effective range of a 45 Colt revolver is typically 50-75 yards, though experienced shooters may extend that slightly, but the bullet drop becomes significantly more pronounced at extended distances.
Comparing the two cartridges is stark in terms of raw power. The 45-70’s bullet will hit a target with significantly more energy at the same distance. The 45-70 offers a distinct advantage at the longer end of the spectrum. The 45 Colt maintains its value in the revolver setting where the portability and handling are paramount. Modern loads have done much to improve the 45 Colt’s overall performance, making it more effective than it once was.
