The .308 Winchester
The story of these cartridges begins not in a sterile laboratory, but in the crucible of history. Understanding their origins provides crucial insight into their design and intended purpose.
The .45-70 Government, also known as the .45-70, first thundered onto the scene in the 1870s. Born from the needs of the United States Army, it replaced the .50-70. Its genesis was tied to the shift toward metallic cartridge breech-loading rifles and the need for a powerful, reliable round for the infantry. The “45” signifies the bullet’s nominal diameter – a hefty 0.45 inches. The “70” refers to the black powder charge, originally a charge of seventy grains of black powder. This cartridge, when loaded with black powder, delivered a devastating blow, playing a pivotal role in the settlement of the American West and the Indian Wars. Its sheer power made it a formidable weapon in the hands of soldiers and frontiersmen, able to bring down large game and defend against hostile encounters. Its legacy is deeply interwoven with the romanticized narratives of the Wild West, making it a favorite among collectors and enthusiasts who appreciate its history and raw power.
In contrast, the .308 Winchester arrived on the scene in the mid-twentieth century, a product of postwar advancements in ammunition and rifle technology. Developed in the 1950s, the .308 Winchester was, in many ways, a refinement of military cartridge design, building on the 7.62x51mm NATO cartridge. This was an answer to the need for a more efficient, versatile, and accurate round compared to previous military offerings. The .308 quickly found its way into civilian hands, embraced by hunters and target shooters alike. It quickly established itself as a staple of bolt-action rifles. It represents a step forward in terms of efficiency and performance. Its flatter trajectory, long range capabilities and widespread availability ensured its rapid success. It is a testament to the continuous evolution in ammunition design and ballistic science.
Ballistic Performance: A Head-to-Head Comparison
Bullet Weight and Size
The heart of any cartridge comparison lies in its ballistics: the science that governs a bullet’s flight. Here, we examine the .45-70 and .308, focusing on key performance characteristics.
The .45-70, with its wider diameter, is often paired with bullets ranging from 300 to 500 or more grains. This heavier bullet weight contributes to its reputation for sheer power. The massive lead slugs, designed for maximum impact, deliver a substantial punch upon impact. The .308, on the other hand, generally utilizes bullets from 150 to 180 grains. These bullets, while lighter, are designed with different purposes in mind. The .308, thanks to its high velocity, makes for a very efficient cartridge. The difference in bullet weight directly influences their performance downrange, which is crucial to consider.
Velocity and Trajectory
Velocity and trajectory are intimately linked. The .45-70, with its heavier and slower bullet, exhibits a more curved trajectory. This means its bullet drops more dramatically over distance, necessitating careful adjustments to compensate for bullet drop at longer ranges. The .308, by contrast, enjoys a much flatter trajectory. Its bullets travel at a higher velocity, resulting in less bullet drop and making it easier to hit targets at varying ranges. This flatter trajectory is a significant advantage for hunters and target shooters who require accuracy at extended distances.
Energy and Stopping Power
Energy transfer, often measured in foot-pounds, is a critical element of a bullet’s effectiveness, and the .45-70 and .308 deliver energy in different ways. The .45-70, with its heavier bullet and large diameter, typically starts with a higher muzzle energy. However, this energy depletes more rapidly as the bullet travels downrange due to the aerodynamic drag. The .308’s higher velocity allows it to maintain its energy over a greater distance. This characteristic, while not boasting the same initial power, provides more consistent downrange performance. This difference becomes particularly important when considering hunting effectiveness.
Recoil
Recoil is another significant factor that directly affects the shooting experience and the shooter’s ability to maintain accuracy. The .45-70, particularly when loaded with heavier bullets, is known for its substantial recoil. This can require a greater level of training and experience to manage effectively. The .308, in comparison, typically generates less recoil, making it more comfortable to shoot for extended periods, and facilitating quicker follow-up shots. This aspect can be a critical consideration for shooters of all experience levels.
Hunting Applications: Where Each Cartridge Shines
The .45-70
The optimal choice between these two cartridges depends heavily on the type of game you pursue and the environment you hunt in.
