The Hornady 45-70 LeverEvolution ammunition has revolutionized the way we think about the venerable 45-70 Government cartridge. Its unique design allows for significantly increased velocity and flatter trajectory compared to traditional 45-70 loads, opening up new possibilities for hunters and shooters alike. This article will delve into the ballistics of this popular ammunition, exploring its performance characteristics and comparing it to traditional rounds.
Understanding LeverEvolution's Innovative Design
The key to LeverEvolution's superior ballistics lies in its patented FlexTip™ bullet design. This bullet features a polymer tip that allows for a much higher ballistic coefficient (BC) compared to traditional lead or jacketed bullets. The polymer tip reduces drag, leading to a flatter trajectory and increased downrange energy. Furthermore, the bullet's construction ensures reliable feeding in lever-action rifles, a feature that was often problematic with heavier, traditional 45-70 loads.
Key Ballistic Differences: LeverEvolution vs. Traditional 45-70
The following table illustrates the key differences in ballistics between a typical 300-grain jacketed 45-70 round and a Hornady 325-grain LeverEvolution round (data may vary slightly depending on barrel length and specific load):
| Characteristic | Traditional 45-70 (300gr) | LeverEvolution (325gr) |
|---|---|---|
| Muzzle Velocity (fps) | ~1800-2000 | ~2200-2400 |
| Muzzle Energy (ft-lbs) | ~2000-2500 | ~3000-3500 |
| Trajectory at 200 yards | Significantly dropping | Relatively Flat |
| Effective Range | Moderate | Extended |
As you can see, the LeverEvolution round boasts a significantly higher muzzle velocity and energy, translating to a flatter trajectory and extended effective range. This makes it ideal for longer shots on game, where accuracy is paramount.
Analyzing the Impact of Higher Velocity
The increased velocity of the LeverEvolution ammunition has several impactful consequences:
- Increased Range and Accuracy: The flatter trajectory allows for more precise shots at longer distances, reducing the need for extensive holdovers or adjustments.
- Greater Penetration: Higher velocity contributes to greater penetration on game, resulting in more effective hunting performance.
- Improved Energy Retention: Although it starts with higher energy, the higher BC of the FlexTip™ bullet helps it retain more energy downrange, enhancing its effectiveness at longer distances.
Considerations for LeverEvolution Usage
While LeverEvolution offers significant advantages, users should consider the following:
- Barrel Length: Longer barrels generally yield higher velocities and therefore better ballistic performance.
- Rifle Compatibility: Ensure your lever-action rifle is compatible with high-velocity 45-70 ammunition; consult your firearm's manual before using LeverEvolution.
- Recoil: The increased velocity results in increased recoil, which might be more noticeable for shooters accustomed to traditional 45-70 loads.
Conclusion: A Powerful Upgrade for the 45-70
Hornady's LeverEvolution ammunition represents a significant advancement in 45-70 technology. Its superior ballistics, stemming from the innovative FlexTip™ bullet design, offer hunters and shooters increased range, accuracy, and effective power. While recoil is slightly increased, the benefits of enhanced performance often outweigh this consideration. For those seeking the best possible performance from their 45-70 lever-action rifle, the LeverEvolution line is undoubtedly worth exploring. Always prioritize safety and consult your firearm's manual before using any ammunition.
