A Glimpse Into History: The Genesis of a Legend
The story of the 45-70 begins with the United States Army’s need for a more potent and reliable cartridge in the late 19th century. The year was 1873, and the U.S. Army officially adopted the 45-70-405 cartridge, marking a pivotal moment in firearms history. The “45” referred to the bullet’s diameter in hundredths of an inch, specifically 0.45 inches. The “70” signified the original charge of black powder in grains, though this charge would evolve with the advent of smokeless powders. The “405” referred to the bullet’s weight in grains, in this initial load.
The primary weapon that embraced this revolutionary cartridge was the Springfield Model 1873 “Trapdoor” rifle. This single-shot rifle was the standard-issue weapon for the U.S. Army soldiers during the Indian Wars and beyond. The 45 70 was a significant upgrade from its predecessor, the .50-70 Government. The new cartridge delivered a heavier bullet and a larger powder charge, providing increased stopping power and effective range on the battlefield.
The 45-70’s impact extended beyond the battlefield. It quickly became a favorite among civilian hunters and frontiersmen. The powerful round proved to be devastating against various North American game animals, securing its place in the annals of hunting lore. This was a time of westward expansion, rugged individualism, and a genuine appreciation for the raw power this cartridge delivered. The 45 70 cartridge became as symbolic of the American West as the Colt Single Action Army revolver.
The Hunter’s Companion: Taking Down Game
The 45-70’s effectiveness is not confined to the pages of history; it continues to be a popular choice for hunters across the continent. The cartridge is renowned for its ability to bring down a wide variety of game, from whitetail deer and black bear to elk and even larger, tougher animals. Its reputation for delivering a decisive blow is well-earned, making it a reliable option for hunters who demand performance.
The key to the 45-70’s hunting prowess lies in the combination of a heavy bullet and a sizable powder charge. The large, typically lead-based bullets of the 45-70, often weighing between 300 and 500 grains, carry significant mass and kinetic energy. This mass delivers a substantial impact upon contact with the target. Unlike the faster, lighter bullets of modern cartridges that rely on high velocity to transfer energy, the 45 70 cartridge’s approach is based on raw stopping power.
This “knockdown” effect is highly valued by hunters. When a 45 70 bullet strikes its target, it delivers a massive transfer of energy that can quickly incapacitate even the largest game animals. While the bullet speed may not be as impressive as some more modern cartridges, the effect is what truly matters. A well-placed shot with a 45 70 can often bring down an animal quickly and humanely, preventing unnecessary suffering.
When hunting with a 45 70, hunters must consider its effective range. While it can certainly reach out beyond 200 yards, the trajectory of the bullet becomes increasingly curved at longer distances. This requires the hunter to carefully compensate for bullet drop to ensure an accurate shot. The 45 70 is often more effective at shorter to medium ranges, where its power can be unleashed with the most effect.
The slow bullet speeds also provide some advantages for the hunter. They can be advantageous in dense cover or thick brush, where a slower bullet is more likely to stay on its course, as opposed to deflecting on the limbs or foliage. Additionally, the slower velocity makes the bullet less sensitive to wind drift at moderate ranges, improving accuracy.
Hunters can tailor their ammunition choices depending on the size of game they pursue. Lighter bullets can be effective for deer-sized game, while heavier bullets are often preferred for elk, bears, and other large animals. Choosing the correct bullet type (e.g., soft-point, hollow-point) and weight can optimize the cartridge’s performance for specific hunting scenarios. The bullet selection process is critical for maximizing performance.
Beyond the Hunt: Target Shooting and Recreational Pursuits
The 45-70’s versatility isn’t restricted to hunting; it has found a beloved place in the realm of target shooting and recreational activities. This iconic cartridge has carved a niche in several shooting disciplines.
The 45 70 is an essential component of Cowboy Action Shooting (CAS). This thrilling sport revives the spirit of the Old West, with competitors dressing in period attire and using historically accurate firearms. Lever-action rifles, such as the Winchester Model 1873 and the Marlin Model 1895, chambered in 45 70, are staples of CAS. The cartridge’s historical significance and manageable recoil make it well-suited for the fast-paced action of CAS, and many CAS enthusiasts relish the feeling of shooting a firearm that harkens back to the days of cowboys and outlaws.
While the 45 70’s trajectory isn’t ideally suited for long-range competitive shooting when compared to dedicated long-range cartridges, it can still deliver surprisingly good results at specific distances. At ranges of 300 to 500 yards, a properly loaded 45 70 can be a formidable target-shooting round. The key is selecting the right bullet weight, charge, and employing careful trajectory calculations to account for bullet drop.
For many shooters, the 45 70 is simply a source of pure enjoyment. The feeling of shouldering a rifle chambered in 45 70, the sound of the shot, and the satisfying impact of a well-placed round are a source of immense satisfaction. The cartridge’s historical connection and its reputation for power make it an appealing choice for casual target shooting, and range days with the 45 70 are a special experience for many firearm enthusiasts.
Advantages and Disadvantages: A Balanced Perspective
Like any cartridge, the 45 70 possesses its advantages and disadvantages. Understanding both sides of the equation is critical for anyone considering using the 45 70 for hunting or recreational shooting.
On the plus side, the 45 70 offers exceptional stopping power and is particularly effective at bringing down large game. Its historical significance is attractive for collectors and those who appreciate classic firearms. The cartridge has a great range of bullet weights and loadings to tailor it to different needs. Moreover, ammunition and reloading components are readily available. The reloading process itself is relatively straightforward, making it accessible to those who want to customize their loads.
However, the 45 70 isn’t without its drawbacks. Recoil can be substantial, particularly with lighter rifles or heavy loads, which can make it less comfortable for inexperienced shooters. The curved trajectory of the bullet requires careful compensation for bullet drop, especially at longer ranges. Additionally, the effective range, in many situations, can be less than some modern cartridges. The cost of ammunition can also be a consideration, as the price of factory-loaded 45 70 rounds is often more expensive than other cartridges.
