The Big Bore Battle: A Look at 450 Bushmaster and 45-70 Government

A Journey Through Time and Innovation

The rumble of a large-bore rifle is a siren song to many firearm enthusiasts. The promise of massive energy transfer, decisive stopping power, and the thrill of hunting big game are powerful draws. Two cartridges stand out in this realm, each with a distinct history, design, and intended purpose: the 450 Bushmaster and the venerable 45-70 Government. This article will delve deep into a comprehensive comparison, exploring their origins, specifications, performance in the field, ammunition considerations, and which cartridge might be the best fit for your needs.

The Roots of These Cartridges

The genesis of these two cartridges paints a fascinating picture of firearms history. The 45-70 Government is a true icon, born in an era of rapid technological advancement. It was originally designed for the U.S. military in the late 19th century, finding its place in the hands of soldiers and frontiersmen alike. This cartridge became synonymous with the American West, aiding in the expansion and defense of the nation. Its legacy is etched into the annals of hunting and firearms lore, its reputation built on decades of service.

The Birth of a Modern Cartridge

In contrast, the 450 Bushmaster represents a modern adaptation, a product of contemporary firearms engineering. Designed in the early 2000s, its creation was driven by a specific need: to provide hunters with an effective cartridge for states with straight-walled cartridge regulations. This modern design allows for hunting in areas with restrictions against bottlenecked cartridges. The 450 Bushmaster takes advantage of modern manufacturing and materials, offering a blend of power and practicality tailored to the demands of the modern sportsman.

Deciphering the Dimensions and Ballistics

Understanding the Physical Differences

Understanding the physical characteristics of these cartridges is crucial to comparing their performance. The 45-70 Government, with its larger overall length, and a bullet diameter of approximately .458 inches, hints at its heritage. This cartridge often loads heavier bullets, resulting in substantial momentum.

Modern Case Design

The 450 Bushmaster also utilizes a .452-inch diameter bullet. The design of the case is straight-walled, and the cartridge itself is comparatively compact, a crucial factor for its compatibility with modern semi-automatic platforms.

Ballistics Tables Revealed

Ballistics tables offer a compelling view of how these dimensional differences translate into real-world performance. The 45-70, with its historical roots, sees a wide variety of bullet weights available. The 45-70 loads tend to offer a flatter trajectory with a wider bullet weight range, with the heaviest loads delivering significant energy.

The Bushmaster’s Trajectory

The 450 Bushmaster, optimized for moderate ranges, is known for its relatively flat trajectory at typical hunting distances. The cartridge is designed to provide impressive stopping power with less recoil than some of the heavier 45-70 loads.

Distinct Design Philosophies

The differences in ballistics highlight their distinct design philosophies. The 45-70 offers a broad range of energy and potentially greater effective range, while the 450 Bushmaster prioritizes performance in the typical hunting range and ease of use in modern firearms.

Arms and the Cartridges

Classic and Timeless Platforms

The firearms platforms available for each cartridge play a significant role in their appeal. The 45-70 Government is frequently associated with lever-action rifles. These firearms, with their classic lines and reliable functionality, are deeply ingrained in the history of the cartridge. Single-shot rifles and rolling-block actions are also platforms that have been successfully chambered in the 45-70. The lever-action rifles offer a combination of nostalgia, ease of operation, and effectiveness.

Modern Platforms and Customization

The 450 Bushmaster embraces modern firearm technology. It is primarily chambered in AR-15 style platforms, with the AR-15’s modular design facilitating easy customization and adaptation. Bolt-action rifles are another common platform for this cartridge, often chosen for their inherent accuracy. The AR-15 platform allows for rapid follow-up shots and ease of operation.

Platform Advantages

The platforms themselves offer varied advantages. The 45-70 offers a sense of historical authenticity and charm, as well as potentially more versatility due to the wide array of loads available. The 450 Bushmaster delivers a modern design, superior ergonomics, and excellent accessory compatibility. This caters to a contemporary shooting style.

Performance in the Wild

Hunting with the 45-70

Hunting applications reveal the core strengths of both cartridges. The 45-70 Government, with its heavy bullets and substantial energy, has proven its ability to take down a wide array of game, including deer, elk, and even large bears. The 45-70 is known for its deep penetration and devastating wound channels. It is a versatile option for hunters across a range of terrains and game sizes.

The Bushmaster in the Field

The 450 Bushmaster, specifically optimized for hunting in areas with regulations, excels at medium-range hunting. Its power and accuracy make it well-suited for deer, bears, and other similar-sized game. The 450 Bushmaster can effectively perform in straight-walled states.

Comparing Hunting Ranges

Comparing their performance, it’s important to understand the typical hunting ranges. The 45-70, with its potential for heavy loads, might have a longer effective range when used in the appropriate load. The 450 Bushmaster delivers a powerful impact at its intended distance, providing effective energy transfer.

Accuracy and Recoil

Target shooting performance also gives insight into each cartridge’s characteristics. Both cartridges are capable of delivering impressive accuracy when paired with appropriate firearms. Recoil management is an important consideration, with the 45-70’s reputation for significant recoil. The 450 Bushmaster generally produces less felt recoil, which can be a significant factor in terms of comfort and the ability to make accurate follow-up shots.

The Currency of the Cartridge: Availability and Expense

Ammunition Options

Ammunition availability and cost are vital practical considerations. The 45-70 Government, due to its long history, benefits from widespread ammunition availability. A wide range of bullet types and loads are available, catering to both hunting and target shooting needs. The price per round varies depending on the load.

The Bushmaster’s Supply

The 450 Bushmaster, while still relatively popular, has slightly fewer factory ammunition options than the 45-70. Ammunition prices are usually competitive with other large-bore cartridges.

Reloading Benefits

Reloading offers a degree of control over ammunition costs. The 45-70 provides significant flexibility when it comes to handloading, with reloaders being able to tailor loads to match their specific needs. The 450 Bushmaster also can be handloaded and it is also an economical route to shooting.
