Understanding the .45-70 Cartridge
Before diving into the reloading process, a foundational understanding of the .45-70 Government cartridge is crucial. This powerful round, known for its substantial recoil and impressive stopping power, requires precision and attention to detail during reloading. Its large case capacity allows for significant powder charge variations, impacting velocity and accuracy. Understanding these nuances is paramount for safe and effective reloading.
Key Considerations for .45-70 Reloading
-
Case Preparation: Proper case preparation is the cornerstone of successful reloading. This includes resizing, cleaning, and trimming cases to uniform dimensions. Inconsistencies here can lead to pressure issues and potential dangers. Using a quality case trimmer is essential for achieving consistent case length.
-
Powder Selection: Choosing the right powder is critical. Various powders exhibit different burn rates, influencing velocity and pressure. Consult reloading manuals for recommended powder charges and always adhere strictly to the listed data. Experimentation should be approached cautiously and incrementally, prioritizing safety above all else.
-
Bullet Selection: The .45-70 accommodates a wide variety of bullets, ranging from round nose to flat nose designs, each impacting ballistic characteristics. Choosing the right bullet depends on intended use – hunting, target shooting, or black powder substitution. Pay close attention to bullet weight and its interaction with your chosen powder.

- Cleaning: Clean the cases thoroughly to remove any residue.
- Trimming: Trim cases to the recommended length for optimal performance.
2. Powder Charging:
- Weighing Powder: Carefully weigh each powder charge using a precise powder scale. This step is crucial for consistency and safety. Never estimate powder charges.
- Adding Powder: Add the weighed powder charge to each prepared case.
3. Bullet Seating:
- Seating the Bullet: Seat the chosen bullet using a seating die. Ensure the bullet is seated to the correct depth.
4. Priming:
- Adding Primers: Carefully add a large rifle primer to each case using a priming tool. Avoid damaging the primers during this process.
5. Crimping (Optional):
- Crimping the Case: For some bullet designs, crimping the case mouth might be necessary to secure the bullet.
Safety Precautions:
Reloading .45-70 Government ammunition requires utmost caution. Always adhere to these safety guidelines:
- Consult Reloading Manuals: Always consult reputable reloading manuals for recommended load data. Never deviate from these guidelines.
- Use a Powder Scale: Always weigh powder charges accurately. Never guess or estimate.
- Wear Safety Glasses: Protect your eyes at all times.
- Work in a Well-Ventilated Area: Reloading can generate fumes; ensure adequate ventilation.
- Store Ammunition Properly: Store reloaded ammunition in a cool, dry, and secure location.
