The .45-70 Government cartridge, a venerable round with a rich history, continues to be a favorite among hunters and shooters. This guide focuses on Hornady .45-70 load data, providing a detailed look at safe and effective recipes for various applications. Remember, always consult your firearm's owner's manual and Hornady's official loading data before reloading. This information is for educational purposes only and should not be considered a substitute for responsible reloading practices.
Understanding Hornady's .45-70 Offerings
Hornady offers a range of bullets designed specifically for the .45-70, each tailored for different hunting scenarios and applications. These include:
-
Leverevolution® .45-70 Bullets: These uniquely designed bullets feature a low-drag profile allowing for longer ranges and flatter trajectories. They are excellent choices for hunting larger game at extended distances. The reduced recoil is also advantageous for lever-action rifles.
-
RN (Round Nose) Bullets: These traditional round nose bullets are suitable for a variety of uses, from plinking to hunting smaller game at closer ranges. They often provide excellent accuracy and are a cost-effective choice for practice.
-
FN (Flat Nose) Bullets: Similar to RN bullets, but with a flatter profile. This can sometimes impact accuracy but may improve performance in certain applications, though this difference is often subtle.
-
FP (Flat Point) Bullets: These bullets are often preferred for hunting applications as the flat point enhances penetration. The exact advantages often depend on bullet composition (lead, jacketed, etc.)
It's crucial to select a bullet weight and type that aligns with your intended use and firearm. Hornady provides detailed data sheets outlining the best powders, primers, and case sizes for optimal performance with each bullet type.
Key Components of a .45-70 Load
Creating a successful .45-70 load involves carefully selecting several crucial components:
-
Bullet: As discussed above, choose a bullet based on intended use and rifle capabilities. Hornady provides a vast range of options.
-
Powder: Hornady recommends specific powders for each bullet weight and type. Using the wrong powder can lead to dangerous pressure spikes and potential firearm damage. Common powders include IMR 4198, IMR 3031, and H4895, but this list isn't exhaustive. Always follow Hornady's load data precisely.
-
Primer: Large rifle primers (LRPs) are standard for the .45-70. The type of primer can affect ignition consistency, so it’s essential to use the recommended primer type from the data.
-
Case: Use properly prepared cases of the correct size and type for your .45-70. This includes cleaning, resizing, and priming before loading.
