Ballistic Chart: .45-70 Government vs. .308 Winchester
| Characteristic | .45-70 Government (405gr) | .308 Winchester (150gr) | Notes |
|---|---|---|---|
| Bullet Weight (gr) | 405 | 150 | Heavier bullets generally have more stopping power but less velocity. |
| Muzzle Velocity (fps) | ~1800-2200 | ~2700-3000 | Velocity significantly impacts range and energy downrange. |
| Muzzle Energy (ft-lbs) | ~2500-3500 | ~2500-3000 | Energy represents the kinetic force of the bullet upon impact. |
| Effective Range (yds) | ~200-300 | ~600-800 | Effective range depends on accuracy and energy needed for target incapacitation. |
| Recoil | High | Moderate | Recoil is a crucial consideration for shooter comfort and control. |
| Trajectory | High-arcing | Relatively Flat | Trajectory affects bullet drop over distance, influencing aiming adjustments. |
| Cost per round | Moderate to High | Moderate | Ammunition costs can vary depending on brand and availability. |
| Availability | Widely Available | Extremely Widely Available | Ease of finding ammunition is a practical factor. |
In-Depth Analysis: .45-70 vs. .308
.45-70 Government: The Heavyweight Contender
The .45-70 Government is a powerful cartridge with a long and storied history. Its massive bullet delivers devastating energy at close to medium ranges, making it a formidable choice for large game hunting. However, its high recoil and significant bullet drop at longer distances limit its versatility. The .45-70 excels in:
- Large game hunting: Its heavy bullet and substantial energy are highly effective against bear, elk, and other large animals.
- Short to medium-range shooting: The heavy bullet's trajectory is less affected by wind at shorter ranges.
- Lever-action rifles: This cartridge is historically associated with lever-action rifles, offering a classic shooting experience.
.308 Winchester: The Versatile Performer
The .308 Winchester is a highly versatile cartridge known for its accuracy, moderate recoil, and relatively flat trajectory. Its widespread popularity stems from its adaptability across various applications. The .308 shines in:
- Long-range shooting: Its higher velocity and flatter trajectory extend its effective range significantly compared to the .45-70.
- Hunting: Effective against a wide range of game, from deer to larger animals (with appropriate bullet selection).
- Target shooting: Accuracy and predictable ballistics make it a preferred choice for precision shooting.
- Military and Law Enforcement: Its widespread adoption by military and law enforcement speaks to its reliability and effectiveness.
Conclusion: Choosing the Right Cartridge
The best cartridge ultimately depends on your specific needs and preferences. The .45-70 Government is the superior choice for close-range hunting of large game where raw stopping power is paramount. The .308 Winchester, on the other hand, offers superior versatility, accuracy, and range, making it a more suitable option for longer-range hunting, target shooting, and other applications. Consider the intended use, shooting distance, recoil tolerance, and ammunition availability when making your decision.
