458 Win Mag Vs. 45-70: Choosing the Right Big-Bore Rifle

From the Past to the Present: A Tale of Two Cartridges

The .45-70 Government’s Genesis

The story of the .45-70 Government begins long ago, in a time when firearms were evolving rapidly. Born in eighteen seventy-three, it was adopted by the United States Army and quickly became a cornerstone of military and civilian marksmanship. The .45-70 was developed to fire a .45-caliber bullet propelled by seventy grains of black powder. This combination, while seemingly modest by today’s standards, provided significant stopping power at the ranges common in the era. The rifles chambered for this cartridge, like the iconic Springfield Model eighteen seventy-three, were simple, robust, and reliable. They became synonymous with the American West, participating in the frontier’s defining moments. The .45-70 quickly became a favorite among hunters seeking to harvest bison, elk, and other large game. Its legacy endures, as it continues to be an incredibly popular choice for hunters.

The Birth of the .458 Winchester Magnum

Fast forward to the mid-twentieth century, and the hunting world demanded more power. As hunters began to explore the dark continent and its formidable big game, a new standard was needed. The .458 Winchester Magnum emerged in the nineteen fifties, a response to the increasing need for a cartridge specifically designed for dangerous game. Built upon the .375 H&H Magnum case, the .458 Winchester Magnum delivered a massive .458-inch diameter bullet with significantly higher velocity and energy compared to the .45-70. This new cartridge was intended for use against thick-skinned game like elephant, rhino, and Cape buffalo. The goal was simple: to deliver maximum stopping power in a single, decisive shot. The .458 Winchester Magnum revolutionized big game hunting, establishing a new level of performance in a readily available cartridge.

Understanding the Core: Specifications and Performance Metrics

Delving into .45-70 Government’s Design

The essence of any cartridge lies in its core specifications. Let’s take a closer look at the technical aspects of both the .45-70 Government and the .458 Winchester Magnum to understand their capabilities.

The .45-70 Government, despite its age, boasts a simple yet effective design. It typically utilizes bullets with a .458-inch diameter, the same as the .458 Win Mag, but bullet weights are often in the three hundred to five hundred grain range. The cartridge’s case is significantly longer than the original case as ammunition manufacturers have expanded its capability over time. This allows for the cartridge to handle a wide variety of bullet weights and designs, although this flexibility does have a limit. Muzzle velocities can range from approximately thirteen hundred feet per second to two thousand feet per second, based on the load used. The muzzle energy will naturally reflect this, being anywhere between two thousand foot-pounds to around three thousand foot-pounds. Its effective range can vary but is often considered to be around two hundred yards, although experienced shooters can extend this with practice and appropriate loads. Its trajectory is more arced, which means it requires more adjustments for shots over distance.

Unpacking .458 Winchester Magnum Details

The .458 Winchester Magnum, on the other hand, is a different beast altogether. This magnum cartridge sports a longer case and higher pressures. The .458 Win Mag also uses a .458-inch diameter bullet, but the bullet weights are usually similar to, or heavier than the .45-70 with the most popular weights being three hundred to five hundred grain bullets. The .458 Win Mag, however, reaches muzzle velocities in the range of two thousand to two thousand four hundred feet per second. Because of the increased velocity, this results in a massive increase in kinetic energy which can be between three thousand five hundred to five thousand foot-pounds or more, especially with heavier bullets. The flatter trajectory allows it to reach further, and some experienced hunters are able to make accurate shots out to three hundred yards or more. This cartridge’s capabilities are undeniable, and its design is optimized for delivering tremendous power.

Contrasting Capabilities: Assessing the Strengths and Weaknesses

Power on Display

Understanding the specifications is one thing; understanding their implications in the field is another. Here, we delve into the practical considerations that shape the real-world performance of these two cartridges.

The power and stopping potential of each cartridge are fundamentally different. The .458 Winchester Magnum’s higher velocity and kinetic energy result in a more significant impact on target. This translates to enhanced penetration and a greater ability to stop a charging or dangerous animal quickly. This makes it a great choice for those hunting big game. The .45-70 Government, while still packing a punch, falls short in this area. However, a properly loaded .45-70 can easily take down a deer, elk, or black bear. The advantage of the .458 Win Mag’s stopping power comes at the cost of heavier recoil, which can make it challenging to shoot accurately for some hunters.

Range Considerations

Range is another critical factor. Because of its flatter trajectory, the .458 Winchester Magnum has a clear advantage at longer distances. While the .45-70 can certainly reach out, its bullet drops more significantly over distance. This makes precise shot placement more challenging at longer ranges. For the hunter who anticipates shots beyond two hundred yards, the .458 Win Mag is the better choice.

Recoil Impact

Recoil is one of the most important things to consider when picking a rifle. The .458 Winchester Magnum generates significant recoil, especially with heavy loads. This can make follow-up shots more difficult and may discourage some shooters. The .45-70 Government, with its lower recoil, is generally considered more manageable for most shooters. This is especially important if a hunter is new to the cartridge, or if they have a physical limitation that makes handling recoil difficult.

Rifle and Ammunition Economics

The rifles chambered for each of these cartridges are readily available. The .45-70 Government is offered in a wide variety of rifles, from traditional lever-actions to modern single-shot designs. The .458 Winchester Magnum, while not as common, is still available in bolt-action rifles from several manufacturers. The cost of the rifles varies based on the manufacturer, materials, and features. However, in general, .458 Winchester Magnum rifles tend to be more expensive than .45-70 rifles. The ammunition availability of both cartridges is good. Reloading components for both cartridges are readily available, and it is easy to tailor the load to fit your specific needs.

Assessing Versatility

Regarding versatility, both cartridges are capable of taking down a wide variety of game. However, the .458 Winchester Magnum shines when hunting large and dangerous game. The increased power and range make it a great choice for elephant, rhino, Cape buffalo, and other thick-skinned animals. The .45-70 Government, while still a capable hunting cartridge, is more suited to medium-sized game. It can be used effectively on deer, elk, and bears, especially at shorter ranges.

Considering the Hunter’s Toolkit: Reloading and Customization

Benefits of Reloading

The option to reload ammunition adds a whole new layer of possibilities for both cartridges. Reloading allows the hunter to fine-tune the performance of their rifle, optimizing it for their specific hunting needs and preferences.

Reloading can dramatically impact the performance of both cartridges. Handloading provides the flexibility to experiment with different bullet weights, powder types, and primer combinations. This allows you to tailor the cartridge to match your desired game. For the .458 Winchester Magnum, handloading allows you to reduce the recoil. For the .45-70 Government, you can take advantage of the older designs that allowed for smokeless powder to give the cartridge a new lease on life.

Component Availability

The components for reloading are easily available. You can get bullets from a variety of manufacturers, and there are numerous choices for primers and powders. This creates a wide range of possibilities when it comes to ammunition selection. You can also customize the load for your rifle to get the most accurate and consistent results.
