45-70 vs 308 Ballistics: A Comprehensive Comparison Chart and Analysis
Choosing the right cartridge for hunting, target shooting, or self-defense requires careful consideration of various ballistic factors. This in-depth analysis compares the venerable .45-70 Government and the popular .308 Winchester, examining their performance across key metrics to help you make an informed decision.
This comparison goes beyond a simple ballistic chart; we delve into the nuances of each cartridge, exploring their strengths and weaknesses in different applications.
Ballistic Chart Comparison: .45-70 Government vs .308 Winchester
The following chart presents a comparison of typical factory loads for both cartridges. Note that actual ballistic performance can vary depending on ammunition manufacturer, bullet weight, barrel length, and environmental conditions. This data serves as a general guideline.
| Characteristic | .45-70 Government (405gr) | .308 Winchester (150gr) | Notes |
|---|---|---|---|
| Bullet Weight (gr) | 405 | 150 | Heavier bullets generally deliver more stopping power but less velocity. |
| Muzzle Velocity (fps) | ~1800 | ~2800 | Significant velocity difference impacts range and energy downrange. |
| Muzzle Energy (ft-lbs) | ~2000 | ~2700 | Higher muzzle energy generally translates to greater stopping power. |
| Recoil | High | Moderate | .45-70 recoil is substantially more significant than .308 Winchester. |
| Effective Range (yards) | ~200-300 | ~600-800 | .308 Winchester significantly outperforms .45-70 at longer ranges. |
| Trajectory | Steep | Flatter | .308 Winchester offers a flatter trajectory, making long-range shots easier. |
| Typical Application | Big game hunting (short to medium range) | Hunting, target shooting, long-range shooting | Each cartridge shines in specific applications depending on its characteristics. |
In-Depth Analysis: .45-70 Government
The .45-70 Government, a classic black powder cartridge dating back to 1873, is known for its impressive stopping power, particularly at close to medium ranges. Its large diameter and heavy bullets create substantial wound channels, making it exceptionally effective for hunting large game like bear and elk, particularly at shorter ranges. However, its limitations become apparent at longer distances due to its steep trajectory and lower velocity. Recoil is significant, requiring a strong shooter and proper shooting techniques.
In-Depth Analysis: .308 Winchester
The .308 Winchester, a versatile and popular cartridge, offers a balance of accuracy, range, and manageable recoil. Its higher velocity and flatter trajectory provide exceptional long-range accuracy, making it suitable for hunting a wide variety of game, target shooting, and even some long-range precision shooting applications. While not delivering the same raw stopping power as the .45-70 at close range, its accuracy and reach make it far superior at longer distances.
Conclusion: Choosing the Right Cartridge
The "better" cartridge depends entirely on the intended application.
-
Choose the .45-70 Government if: You need maximum stopping power at close to medium ranges for large, dangerous game hunting and recoil is not a major concern.
-
Choose the .308 Winchester if: You require accuracy, a flatter trajectory, and a longer effective range for hunting a wider variety of game, target shooting, or long-range shooting. A more manageable recoil is also an advantage.
Remember to always practice safe firearm handling and consult relevant regulations and laws before using any firearm or ammunition. This comparison provides a general overview; specific ammunition selection and usage should be guided by your individual needs and expertise.
