Choosing the right cartridge for hunting in Alaska, or anywhere for that matter, demands careful consideration. Both the .50 Alaskan and the .45-70 Government are powerful contenders, but their strengths lie in different areas. This in-depth comparison will help you understand which cartridge best suits your needs.
Cartridge Ballistics: A Side-by-Side Comparison
Let's start with the raw numbers. While specific load data can vary significantly between manufacturers, a general comparison reveals key differences:
| Feature | .50 Alaskan | .45-70 Government |
|---|---|---|
| Caliber | .50 caliber (12.7 mm) | .45 caliber (11.5 mm) |
| Case Type | Proprietary, bottlenecked | Straight-walled, belted (often) |
| Bullet Weight (grains) | Typically 350-500+ | Wide range, typically 300-500+ |
| Muzzle Velocity (fps) | Varies greatly depending on load; generally slower than .45-70 | Varies greatly depending on load; generally higher than .50 Alaskan (with lighter bullets) |
| Muzzle Energy (ft-lbs) | Extremely high, exceeding 4000 ft-lbs in some loads | High, often exceeding 3000 ft-lbs, but less than the .50 Alaskan |
| Recoil | Significantly higher than .45-70 | High, but manageable |
.50 Alaskan: The Heavyweight Champion
The .50 Alaskan is designed for serious stopping power. Its large diameter and heavy bullets create devastating wound channels, making it exceptionally effective against large, dangerous game. The sheer energy delivered ensures deep penetration, even through thick hides and bone.
Advantages of the .50 Alaskan:
- Exceptional stopping power: Its massive bullet diameter and weight deliver unparalleled knockdown power.
- Superior penetration: Ideal for taking down thick-skinned animals.
Disadvantages of the .50 Alaskan:
- Extreme recoil: This cartridge is not for the faint of heart. Managing recoil requires significant strength and practice.
- Limited availability: Ammunition and reloading components might be less readily available compared to the .45-70.
- Cost: Generally more expensive than .45-70 ammunition.
.45-70 Government: A Classic with Staying Power
The .45-70 Government boasts a long and storied history, renowned for its effectiveness in hunting large game. While not as powerful as the .50 Alaskan in terms of sheer energy, its versatility and readily available ammunition make it a compelling choice.
Advantages of the .45-70 Government:
- Wide ammunition availability: Finding ammunition is generally easy.
- Manageable recoil (relatively): Compared to the .50 Alaskan, recoil is considerably less, leading to better follow-up shots.
- Variety of bullet weights and types: Allows for tailoring loads to specific game and hunting situations.
- Lower cost: Generally less expensive than .50 Alaskan ammunition.
Disadvantages of the .45-70 Government:
- Less stopping power than .50 Alaskan: Might require more precise shot placement for clean kills on large game.
- Trajectory: The trajectory of heavier bullets can be less forgiving at longer ranges than lighter bullets, which may fly faster but can lack the penetration depth required.
The Verdict: Choosing the Right Cartridge
The "best" cartridge depends entirely on your priorities and hunting style.
-
Choose the .50 Alaskan if: You prioritize maximum stopping power and penetration, and are comfortable with significant recoil. This is a cartridge best suited for experienced hunters who need the ultimate in stopping power in extreme situations.
-
Choose the .45-70 Government if: You value manageable recoil, wide ammunition availability, and a lower cost. Its versatility makes it suitable for a broader range of hunting scenarios. This makes it an excellent choice for a wider range of hunters.
Ultimately, the decision comes down to personal preference, experience level, and the specific hunting conditions you'll face. Consider your own physical capabilities and the type of game you'll be hunting before making your choice. Consult with experienced hunters and firearm professionals to make an informed decision.
