The .45-70 Government cartridge, a venerable round with a rich history, has seen a resurgence in popularity, thanks in part to Hornady's LeverEvolution ammunition. This post delves into the ballistics of Hornady's LeverEvolution .45-70 offerings, examining their performance characteristics and suitability for various hunting and shooting applications. We'll explore factors like velocity, energy, trajectory, and effective range, providing you with the information needed to make informed decisions about your ammunition choices.
Understanding Hornady LeverEvolution Technology
Before diving into the specifics of ballistics, it's crucial to understand what makes Hornady LeverEvolution ammunition unique. Unlike traditional .45-70 ammunition, LeverEvolution utilizes a pointed, polymer-tipped projectile. This design allows for a higher ballistic coefficient (BC), resulting in a flatter trajectory and reduced wind drift compared to traditional round-nose bullets. This is particularly beneficial in lever-action rifles, which often have longer sight radii and can benefit from a more predictable bullet path. The polymer tip also contributes to better accuracy and improved penetration.
Ballistic Data for Hornady LeverEvolution .45-70
The exact ballistic data for Hornady LeverEvolution .45-70 ammunition can vary slightly depending on the specific bullet weight and the rifle used. However, we can provide general performance characteristics based on manufacturer's data and field testing:
Typical Ballistic Characteristics (Approximate):
- Bullet Weight: Ranges from 250 grains to 325 grains. More weight generally translates to increased retained energy at longer ranges, but with a trade-off in velocity.
- Muzzle Velocity: Expect velocities in the range of 2000-2400 fps (feet per second), significantly higher than traditional .45-70 loads. This higher velocity contributes to the flatter trajectory and extended range.
- Muzzle Energy: Muzzle energy will be correspondingly high, typically ranging from 2,000 to 2,800 ft-lbs (foot-pounds). This potent energy is ideal for large game hunting.
- Trajectory: Due to the high BC bullet, the trajectory is noticeably flatter than traditional .45-70 loads, making long-range shots more manageable and accurate.
- Effective Range: While effective range depends on several factors (shooter skill, wind conditions, target size), Hornady LeverEvolution .45-70 ammunition can effectively reach out to significantly greater distances than traditional loads, extending into the 300-yard range for experienced shooters.
Bullet Weight Considerations:
- Lighter Bullets (e.g., 250 grains): These will generally exhibit higher velocities and flatter trajectories, sacrificing some retained energy at longer distances. Suitable for deer-sized game at moderate ranges.
- Heavier Bullets (e.g., 325 grains): These deliver greater knockdown power and retained energy at longer ranges, but with a more pronounced trajectory drop. Ideal for larger game like elk or bear, especially at extended ranges.
Applications of Hornady LeverEvolution .45-70
The superior ballistics of Hornady LeverEvolution .45-70 make it a versatile choice for various applications:
- Big Game Hunting: This ammunition excels in taking down large game animals, including deer, elk, bear, and even moose, especially at extended ranges where traditional .45-70 loads might fall short.
- Lever-Action Rifles: Specifically designed to work reliably in lever-action rifles, reducing feeding and cycling issues commonly associated with pointed bullets in tubular magazines.
- Long-Range Shooting: The flatter trajectory and reduced wind drift contribute to improved accuracy at longer ranges, suitable for target shooting and hunting at extended distances.
Conclusion: A Powerful and Versatile Cartridge
Hornady LeverEvolution .45-70 ammunition offers a significant upgrade over traditional .45-70 loads. The innovative bullet design delivers superior ballistics, making it an excellent choice for hunters and shooters seeking increased accuracy, range, and stopping power. Always consult Hornady's official website for the most up-to-date ballistic data and safety information. Remember to always practice safe firearm handling procedures.
