The .45-70 Government cartridge, a venerable round with a rich history, has seen a resurgence in popularity, largely thanks to Hornady's Leverevolution ammunition. This innovative cartridge design pushes the boundaries of what's possible with the old-school .45-70, offering improved accuracy and flatter trajectory at longer ranges. This article will delve into the ballistics of Hornady Leverevolution .45-70 ammunition, exploring its performance characteristics and suitability for various applications.
Understanding Hornady Leverevolution's Unique Design
Unlike traditional .45-70 rounds that utilize full-metal-jacket (FMJ) or round-nose bullets, Hornady Leverevolution employs a unique, pointed Flex Tip bullet. This design allows for superior ballistic performance compared to its predecessors. The Flex Tip's design is crucial; its polymer tip aids in consistent expansion and better penetration, enhancing accuracy and terminal effectiveness. The lighter weight compared to traditional .45-70 bullets also contributes to a flatter trajectory and reduced recoil, making it suitable for hunting at extended ranges.
Key Ballistic Advantages of the Flex Tip Design:
- Improved Accuracy: The pointed bullet design reduces the yaw (wobble) experienced by round-nose bullets, leading to greater accuracy at longer ranges.
- Flatter Trajectory: The lighter projectile weight results in a flatter trajectory, making shot placement easier at longer distances.
- Reduced Recoil: The lighter bullet, combined with the efficient powder charge in Hornady Leverevolution, contributes to a more manageable recoil impulse, increasing shooter comfort and follow-up shot capability.
- Controlled Expansion: The Flex Tip design ensures consistent expansion on impact, offering reliable performance in hunting situations.
Examining the Ballistic Data
Precise ballistic data varies depending on the specific load (bullet weight, powder charge) and environmental factors (temperature, altitude, humidity). However, general observations based on Hornady's published data and field tests indicate the following performance characteristics:
- Muzzle Velocity: Hornady Leverevolution typically exhibits muzzle velocities ranging from approximately 2000-2200 fps, significantly higher than traditional .45-70 loads. This higher velocity is a major contributor to the improved range and accuracy.
- Energy Retention: While energy drops off with distance, the Leverevolution round maintains significant energy at extended ranges, making it effective for hunting larger game.
- Effective Range: While not a long-range cartridge in the typical sense, the Leverevolution expands the effective range of the .45-70 significantly compared to its traditional counterparts, often up to 200 yards or more, depending on the hunter's skill and conditions. However, responsible hunters should always practice and know their personal limits.
Leverevolution's Applications: Hunting and Beyond
Hornady Leverevolution's improved ballistics make it an excellent choice for a variety of applications:
Hunting:
- Large Game Hunting: The .45-70 Leverevolution is exceptionally well-suited for hunting large game animals within its effective range. It delivers devastating stopping power, ensuring a quick, clean kill. This makes it a potent cartridge for animals such as deer, elk, and bear (depending on regulations and ethical hunting practices).
- Improved Accuracy at Longer Ranges: The flatter trajectory and superior accuracy compared to standard .45-70 ammo extend the hunter's ethical shooting range, increasing the chances of a clean, humane harvest.
Other Uses:
While hunting is the primary application, some enthusiasts use the Leverevolution round for target shooting and practicing long-range skills. However, the relatively high cost of this ammunition makes it less appealing for pure target practice compared to other less expensive cartridges.
Conclusion: A Modern Twist on a Classic Cartridge
Hornady Leverevolution ammunition has successfully modernized the venerable .45-70 cartridge. Its unique design and superior ballistics offer enhanced accuracy, flatter trajectory, and improved performance compared to traditional loads, expanding its effective range and making it a viable option for hunters seeking a powerful, versatile, and accurate round for larger game. However, always remember safe firearm handling and adhere to all relevant hunting regulations.
