best powder for 45-70

The .45-70 Government cartridge, a venerable round with a rich history, demands careful consideration when selecting the right powder. Choosing the best powder isn't just about achieving the highest velocity; it's about finding the optimal balance between accuracy, pressure, and the specific application—whether it's hunting large game, target shooting, or even Cowboy Action Shooting. This guide will help you navigate the complexities of .45-70 powder selection.

Understanding Your Needs: Application Matters

Before diving into specific powders, it's crucial to define how you'll be using your .45-70. Different applications have different needs:

Hunting:

Hunting requires a powder that delivers sufficient velocity and energy for reliable stopping power at hunting ranges. This often means prioritizing a magnum load for heavier bullets at longer distances. Accuracy and consistency are paramount.

Target Shooting:

Target shooting emphasizes accuracy and consistent performance. You might prioritize a powder that provides a lower recoil impulse for better follow-up shots.

Cowboy Action Shooting:

This discipline often involves using black powder substitutes or slower-burning powders to mimic the feel and characteristics of historical black powder loads. Reliability and consistent performance are key here, too.

Top Powder Choices for .45-70:

Several excellent powders consistently perform well in the .45-70. The following are some of the top contenders, categorized for clarity:

For Maximum Power and Hunting:

  • IMR 4198: A versatile, medium-burning powder suitable for heavier bullets. It offers a good balance of power and accuracy, making it a popular choice for hunting loads.

  • IMR 4350: Another excellent choice for heavier bullets and longer ranges, IMR 4350 provides high velocity and good accuracy. This powder works exceptionally well with heavier bullets.

  • Hodgdon H4895: Known for its consistent burning rate and excellent accuracy, H4895 is a go-to option for many .45-70 shooters. It works well across a range of bullet weights.

  • Reloder 7: This powder delivers impressive performance with heavier bullets, offering high velocity while maintaining manageable recoil.

For Lighter Recoil and Target Shooting:

  • Accurate Arms #9: This powder provides excellent accuracy and a smoother recoil impulse, making it well-suited for target shooting. It’s known for its finer metering and cleaner burning.

  • Unique Powder: A classic choice for lower-velocity loads, Unique is a versatile powder that is relatively easy to work with. It's more commonly found in milder loads.

Considerations Beyond Specific Powders:

  • Bullet Weight: The weight of your bullet significantly impacts powder selection. Heavier bullets generally require a slower-burning powder, while lighter bullets often perform best with faster-burning powders.

  • Case Capacity: The capacity of your .45-70 cases varies slightly depending on the manufacturer and case headstamp. Always double-check your case capacity to ensure you stay within safe pressure limits.

  • Manuals are Crucial: Always consult the reloading manuals from the powder manufacturer (Hodgdon, IMR, Alliant, etc.) for specific load data relevant to the bullet you're using. Never exceed the maximum recommended charge listed in the manuals!

  • Safety First: Reloading is inherently dangerous. Always wear appropriate safety equipment, follow proper safety procedures, and handle all components with extreme caution.

Conclusion:

Selecting the best powder for your .45-70 Government hinges on the intended application and the bullet weight. While this guide highlights some excellent options, remember to conduct thorough research and always consult reloading manuals for accurate load data. Safe and responsible reloading practices are paramount. With careful selection and adherence to safe reloading procedures, you can find the perfect powder combination to optimize your .45-70 performance.
