The .45-70’s story began in the late 1800s. Developed for the U.S. Army, it replaced the .50-70 Government, a cartridge that had shown its limitations. The .45-70, with its larger bullet and improved powder, quickly proved its worth. The “45” refers to the bullet diameter in hundredths of an inch (.45 inches), and the “70” indicates the black powder charge in grains. Originally chambered in the Springfield Model 1873 “Trapdoor” rifle, the .45-70 served as the primary military cartridge for nearly two decades, playing a pivotal role in shaping the American frontier.
Its effectiveness wasn’t lost on civilian hunters and settlers. The cartridge’s substantial power and flat trajectory at moderate ranges made it ideal for taking down large game, from bison and elk to deer and black bear. The .45-70 quickly earned a reputation for its stopping power, capable of putting down animals quickly and cleanly.
Modern times have seen a renewed interest in the .45-70. While it has faded somewhat from its initial military application, the .45-70’s continued use and popularity are undeniable. Its versatility allows it to excel in various fields, from hunting to sport shooting, allowing it to carve a new niche in contemporary shooting. It’s found favor with hunters seeking a powerful cartridge for close-range encounters, target shooters who appreciate its inherent accuracy and the classic rifle platforms it is often found in, and cowboy action shooters drawn to its historical significance.
Introducing the Hornady Leverevolution Advantage
To truly understand the modern relevance of the .45-70, we must consider the innovation that has breathed new life into this iconic cartridge: Hornady Leverevolution ammunition. Hornady, a leader in ammunition innovation, recognized the potential of this classic round and developed a unique bullet design specifically for lever-action rifles, the most common platform for the .45-70.
The key to Leverevolution’s success lies in its Flex Tip bullet design. This revolutionary feature replaces the traditional, rigid bullet tip with a soft, flexible polymer tip. This seemingly minor change has a profound impact on the bullet’s performance. Because of the flexible tip, it is completely safe in the tube magazine of lever-action rifles, which can sometimes result in accidents with pointed bullets. This innovative design provides a significant advantage in several key areas.
The Flex Tip design allows for a higher ballistic coefficient (BC). BC measures a bullet’s ability to overcome air resistance. A higher BC means the bullet will retain its velocity and energy over a longer distance, resulting in a flatter trajectory and less drop at longer ranges. The Flex Tip also promotes better terminal ballistics. Upon impact, the flexible tip initiates rapid expansion, transferring maximum energy to the target. This delivers more effective energy transfer and quicker, more humane kills when hunting.
Leverevolution ammunition for the .45-70 is available in several bullet weights and styles, with the 325-grain FTX being particularly popular. This bullet weight offers an excellent balance of velocity, energy, and trajectory, making it a versatile choice for various hunting situations.
Decoding the Hornady Leverevolution 45-70 Ballistics Chart
The heart of understanding the Hornady Leverevolution 45-70 is the ballistics chart itself. This chart is a detailed summary of the ammunition’s performance, providing crucial information for hunters and shooters to accurately assess its capabilities. Let’s break down the key data points and explore what they mean:
The ballistics chart starts with the muzzle velocity. This is the speed at which the bullet leaves the muzzle of the rifle, typically measured in feet per second (fps). Higher muzzle velocities generally translate to flatter trajectories and more energy downrange. For Hornady Leverevolution in the .45-70, the muzzle velocity of the 325-grain FTX bullet is usually around 2050 fps, though this can vary slightly depending on the barrel length of the rifle.
Next, the chart lists the ballistic coefficient (BC). The BC is an important factor affecting the bullet’s trajectory. A higher BC allows the bullet to maintain its velocity and energy over longer distances, meaning the bullet has a more efficient shape and can resist the slowing effects of air drag. This helps in reducing the amount of drop the bullet will experience over a certain range.
The chart will include the zero range. This is the distance at which the bullet’s path intersects with the line of sight of the scope or sights. At this distance, the bullet will strike at the point you aim. Understanding the zero range is crucial for precise shooting, as it helps in determining how high or low the bullet will impact at different distances. In the example of the 325-grain FTX, the typical zero range might be around 100 yards.
The most important data found within the ballistics chart is the trajectory data itself, providing information on the bullet’s path throughout its flight. This data includes the bullet drop at different ranges (e.g., 50, 100, 150, 200, 250, 300 yards). The bullet drop is usually measured in inches (or centimeters) and indicates how far below the line of sight the bullet will impact at a specific distance. This data is critical for making accurate shots at varying ranges. For instance, a .45-70 bullet might drop several inches at 200 yards, requiring the shooter to compensate for the drop by aiming slightly higher.
The chart also lists the energy figures, or the amount of kinetic energy the bullet carries at each range. This is measured in foot-pounds (ft-lbs) and is a crucial metric for determining the bullet’s effectiveness on target. A higher energy level at impact will transfer a greater amount of energy to the target, resulting in a more significant impact and, for hunters, more effective terminal performance.
Finally, some ballistics charts may include wind drift data, indicating how much the bullet will be pushed sideways by the wind at different distances. This is an important factor to consider when shooting in windy conditions, and understanding wind drift allows shooters to compensate for the effect of wind by aiming slightly into the wind.
Analyzing Performance and Capabilities
Let’s break down the implications of these numbers for a typical Hornady Leverevolution .45-70 load, focusing on the 325-grain FTX bullet.
The muzzle velocity of around 2050 fps provides a solid foundation for effective performance, generating substantial energy. As the bullet travels downrange, it slowly loses velocity due to air resistance.
Considering the trajectory, we can understand how the bullet drops. A .45-70 bullet, with its relatively heavy weight, experiences a significant drop compared to high-velocity, flatter-shooting cartridges at longer ranges. However, the Flex Tip design helps to mitigate this, providing a more predictable trajectory than other bullet designs. The shooter has to be sure to use the bullet drop data from the ballistics chart to make any appropriate aiming adjustments.
The energy retention is impressive. Even at 200 or 250 yards, the Hornady Leverevolution .45-70 still delivers substantial energy, making it a viable choice for hunting large game at moderate distances. This makes it very useful when hunting big game animals such as elk, deer, or even bear.
The wind drift for a .45-70 bullet can be noticeable, especially at longer ranges or in strong winds. This is why it is very important to account for these conditions when aiming.
Key Factors that can affect Ballistics
Several elements can influence the performance of the Hornady Leverevolution 45-70 ammunition:
Environmental factors can play a significant role in affecting bullet trajectory and accuracy. Altitude, for example, can influence air density, affecting the bullet’s flight path. Temperature affects the air density and powder combustion, and can impact velocity. Humidity can also play a role, particularly at extremely high levels. Wind, as previously mentioned, can push the bullet off course, requiring shooters to make adjustments to compensate.
The quality of your rifle and scope is also very important. A high-quality rifle with a well-maintained barrel and a properly mounted scope will greatly improve accuracy and consistency. It is imperative to sight in your scope at the appropriate distance, based on your intended use. This way, the bullet will strike at the point of aim.
Bullet performance also depends on how the bullet is constructed. Different bullet types are designed for different purposes. Hornady’s Flex Tip is constructed to promote rapid expansion on impact, which delivers exceptional energy transfer and a quick, clean kill when hunting.
