This iconic ammunition, available exclusively at DEGuns, embodies decades of Remington's commitment to quality and hunting success.

The Enduring Legacy of the 45-70 Government Cartridge

When considering ammunition for formidable game, the 45-70 Government cartridge often comes to mind. Developed in 1873 for the U.S. Army's Springfield Model 1873 Trapdoor rifle, this cartridge quickly cemented its place in history, known for its sheer power and versatility. While originally designed for military applications, its robust capabilities soon found favor among hunters pursuing large North American game. From the vast plains to dense forests, the 45-70 Government has proven its efficacy on deer, elk, moose, and even formidable bears.

What makes the 45-70 Government so relevant today, nearly 150 years after its inception? Its large bore diameter and heavy bullet weight translate into exceptional kinetic energy transfer upon impact, delivering profound stopping power. This characteristic is particularly crucial for ethical hunting, ensuring swift and humane harvests. Hunters often ask, "What is the best ammunition for brush hunting?" or "Which cartridge provides reliable knockdown power at moderate ranges?" The 45-70 Government, especially when paired with a bullet like the Remington Core-Lokt, provides a resounding answer. Its heavy, blunt-nosed bullets are less susceptible to deflection by light brush compared to smaller, faster projectiles, making it an excellent choice for thick cover where shots are often taken at closer distances.

Unleashing "The Deadliest Mushroom": Remington Core-Lokt Technology

At the heart of the Remington R4570G1's performance is the legendary Core-Lokt bullet. Introduced in 1939, Core-Lokt quickly earned its reputation as "The Deadliest Mushroom" due to its unparalleled controlled expansion. This isn't just marketing jargon; it's a testament to a foundational bullet design that has remained a favorite among hunters for generations.

So, how does Core-Lokt achieve this superior performance? The secret lies in its meticulously engineered construction. Each Core-Lokt bullet features a precisely designed lead core mechanically locked to a progressively tapering copper jacket. This innovative design ensures two critical outcomes upon impact:

• Controlled Expansion: Unlike bullets that might fragment prematurely or fail to expand at all, the Core-Lokt's design facilitates consistent, reliable expansion into a large, mushroom shape. This maximizes energy transfer and creates a devastating wound channel, vital for clean, ethical kills.
• High Weight Retention: The mechanical lock between the core and jacket prevents the lead core from separating from the jacket. This high weight retention means that the bullet maintains its mass and momentum as it penetrates, driving deeper into vital organs. For hunters pursuing large, thick-skinned game, deep penetration coupled with controlled expansion is the ultimate combination for achieving decisive terminal performance.

Many hunters ponder, "What kind of bullet provides the best balance of expansion and penetration?" or "How does bullet design affect hunting success?" The answer, often highlighted by decades of field experience, points directly to the principles embodied by the Core-Lokt. Its soft point (SP) nose initiates expansion reliably upon impact, even at the lower velocities characteristic of many 45-70 loads, making it an ideal pairing for this cartridge.

Key Features and Benefits of Remington R4570G1 Core-Lokt 45-70 Gov 405 gr

The Remington R4570G1 specifically loads the 45-70 Government cartridge with a 405-grain Core-Lokt Soft Point bullet. This particular bullet weight and design are highly regarded for their effectiveness on a wide range of game.

• Exceptional Stopping Power: The combination of the heavy 405-grain projectile and the Core-Lokt's controlled expansion delivers tremendous knockdown power. This is crucial for stopping large game quickly and efficiently, minimizing tracking and ensuring a humane harvest.
• Reliable Performance: Hunters need ammunition they can trust shot after shot, season after season. Remington's manufacturing quality ensures consistent primer ignition, uniform powder charges, and precise bullet seating, leading to reliable feeding and consistent ballistic performance.
• Versatility for Big Game: Whether you're hunting whitetail deer in dense woods, elk in open country, or planning a challenging black bear or even brown bear hunt, the 45-70 Gov 405 gr Core-Lokt Soft Point is engineered to perform. Its design excels in scenarios where deep penetration and significant tissue damage are required.
• Optimized for Lever-Action Rifles: Many enthusiasts of the 45-70 Government cartridge favor classic lever-action rifles. The R4570G1 ammunition is designed to feed smoothly and reliably in these timeless firearms, honoring the heritage of the cartridge itself. This makes it an excellent choice for those asking, "What is the best ammunition for my lever-action 45-70?" or "Which 45-70 ammo is reliable in tube magazines?"
• Ethical Hunting Choice: For hunters committed to ethical practices, the R4570G1 provides the confidence needed to make clean, one-shot kills. The bullet’s design ensures maximum energy transfer and tissue disruption, leading to swift incapacitation.
• Trajectory and Ballistics: While not a long-range cartridge by modern standards, the 45-70 Government with a 405-grain Core-Lokt bullet offers a flatter trajectory than many might expect at typical hunting distances (up to 150-200 yards). With a muzzle velocity of approximately 1330 feet per second and muzzle energy around 1588 foot-pounds, this load delivers substantial power where it counts. Its energy retention ensures effective performance even at extended ranges for this caliber.
• Proudly Made: Remington has a long-standing heritage in American ammunition manufacturing, and the Core-Lokt line upholds that tradition of quality and performance.

Real-World Hunting Scenarios and User Outcomes

Imagine being deep in the Alaskan wilderness, facing a formidable brown bear, or tracking a majestic elk through the Rocky Mountains. In such critical moments, the choice of ammunition can mean the difference between success and failure, or even safety and danger. The Remington R4570G1 Core-Lokt provides the assurance that many hunters seek.

• For the Deer Hunter: For those pursuing whitetail or mule deer, especially in areas with thick cover or where quick incapacitation is desired, the 405 gr Core-Lokt delivers. Its broad frontal area upon expansion creates a devastating wound channel, often resulting in short tracking jobs or immediate stops.
• For the Elk or Moose Hunter: When facing the larger bone structure and robust musculature of elk or moose, deep penetration is key. The Core-Lokt's locked core ensures it drives through heavy tissue and bone to reach vital organs, making it a reliable choice for these larger cervids.
• For Bear Defense and Hunting: Many guides and seasoned bear hunters trust the 45-70 Government for its potent stopping power. The 405 gr Core-Lokt is an excellent option for black bear and even larger bears, providing the necessary penetration and energy to deter a charge or ensure a clean harvest.
• The Classic "Thumper" for Traditionalists: For hunters who appreciate the history and raw power of classic cartridges, the 45-70 Government in a traditional lever-action rifle, loaded with Core-Lokt, is a deeply satisfying and highly effective combination. It offers a tangible connection to hunting heritage while delivering modern performance.

Users report increased confidence in the field, knowing their ammunition is designed to perform reliably under pressure. The outcome is often a clean, ethical harvest, minimizing animal suffering and maximizing the hunting experience. This trust in equipment allows hunters to focus on their craft, rather than worrying about ammunition deficiencies.
