- Reloading Press: A sturdy press capable of handling the high pressures associated with the .45-70 is vital.
- Dies: A full set of dies (sizing die, powder measure, bullet seater die, and possibly a crimp die) specifically designed for .45-70 is necessary.
- Powder Measure: An accurate powder measure is critical for consistent powder charges.
- Scale: A digital powder scale ensures precise powder weights.
- Case Trimmer: Trimming cases to uniform length maintains headspace and ensures reliable ignition.
- Bullet Lubricant: Lubricating bullets, especially lead bullets, reduces friction during seating and improves accuracy.
- Case Lube: A case lube helps reduce friction and damage during sizing.
Step-by-Step Reloading Process
The reloading process for .45-70 Government follows the standard steps, but extra attention to detail is required. Here's a detailed breakdown:
1. Case Preparation:
- Cleaning: Thoroughly clean spent cases to remove any residue.
- Sizing: Resize cases to uniform dimensions using your sizing die.
- Trimming: Trim cases to the correct length.
- Deburring: Remove any sharp edges from cases.
2. Powder Charging:
- Weighing: Carefully weigh each powder charge using your scale. Consistency is key for safe and accurate shooting.
- Charging: Add the measured powder charge to each case.
3. Bullet Seating:
- Lubrication: Lubricate bullets if needed.
- Seating: Seat the bullet to the desired depth using your bullet seater die.
