This ammunition is not just another bullet; it's a testament to Winchester's commitment to innovation, offering a solution to the perennial challenge of achieving consistent, devastating on-target energy transfer in a hunting cartridge.

Understanding the Power of the .45-70 Government Cartridge

The .45-70 Government, a cartridge with a storied history dating back to 1873, remains incredibly popular for its potent stopping power and versatility, particularly in lever-action rifles. Originally designed for military use, its robust characteristics quickly found favor among big game hunters. Even today, over a century and a half later, it continues to be a top choice for those targeting large North American game such as moose, elk, bear, and bison, as well as being highly effective in brush country where shorter, heavy bullets excel.

What makes the .45-70 Government so enduringly relevant? Its large diameter and heavy bullet options deliver significant energy transfer upon impact, creating wide wound channels and promoting rapid incapacitation. This cartridge thrives in scenarios where raw power and deep penetration are paramount, making it an ideal companion for the rugged outdoorsman. With the advent of modern propellants and bullet designs like the Winchester Dual Bond, the .45-70 has seen a significant resurgence, pushing its capabilities far beyond its original black powder limitations. It offers hunters the reliability of a classic caliber combined with contemporary ballistic advancements, ensuring it remains a formidable force in the field.

Why Winchester Dual Bond Technology Stands Apart

The core of this ammunition's superior performance lies in Winchester's proprietary Dual Bond technology. Unlike traditional bullets where the core and jacket might separate upon impact, Dual Bond bullets are engineered with a unique, two-stage bonding process. This innovative construction ensures that the lead core is molecularly bonded to the copper jacket from the very tip to the base. This holistic bonding achieves several critical advantages for hunters:

• Controlled Expansion: The Dual Bond bullet is designed to expand reliably and consistently, even at varying impact velocities. This controlled expansion creates a wide, devastating wound channel, maximizing tissue damage and energy transfer within the target. It avoids the fragmentation often associated with lesser bullets, ensuring that the bullet's mass is retained for deeper penetration.
• High Weight Retention: Because the core and jacket are bonded, the bullet retains almost all of its original weight after impact. This high weight retention is crucial for driving the bullet deeper through muscle, bone, and hide, increasing the likelihood of reaching vital organs and ensuring a clean, humane kill. Hunters often report seeing the bullet exit on large animals, signifying complete pass-through and maximum energy delivery.
• Deep Penetration: The combination of controlled expansion and high weight retention directly translates into exceptional penetration capabilities. This is particularly vital when hunting large animals with thick hides or dense bone structures, where ordinary bullets might deform excessively or stop prematurely. The Dual Bond drives through obstacles, ensuring the bullet reaches its intended target.
• Devastating Terminal Performance: The cumulative effect of these features is devastating terminal performance. Hunters using Winchester Dual Bond .45-70 rounds can expect their shot to deliver maximum shock and trauma, leading to quick and ethical takedowns, reducing tracking distances, and providing confidence in every pull of the trigger. This predictable performance minimizes suffering for the animal and maximizes success for the hunter.
