The .220 Swift, known for its blistering speed and flat trajectory, demands precision in reloading. This guide delves into the intricacies of .220 Swift reloading, offering data, techniques, and insights to help you achieve optimal accuracy and performance. We'll cover everything from case preparation to load development, ensuring you get the most out of this exceptional cartridge.
Understanding the .220 Swift Cartridge
Before diving into reloading data, it's crucial to understand the .220 Swift's unique characteristics. Its high velocity necessitates careful attention to detail, as excessive pressure can lead to dangerous consequences. The relatively thin case walls also require gentle handling during processing.
Key Characteristics Affecting Reloading:
- High Pressure: The .220 Swift operates at high pressures, demanding meticulous attention to proper powder charges and case preparation. Overloading is a serious risk.
- Case Capacity: The relatively small case capacity limits powder choices and necessitates precise powder measurements.
- Bullet Selection: Bullet weight and design significantly impact velocity and accuracy. Choosing the right bullet is paramount for optimal performance.
Reloading Equipment and Supplies
Before you begin, ensure you have all the necessary equipment and supplies. Investing in quality tools will contribute to safer and more accurate reloading.
Essential Equipment:
- Reloading Press: A single-stage press is sufficient for beginners, while progressive presses offer increased efficiency for larger reloading volumes.
- Case Trimmer: Essential for maintaining consistent case length.
- Powder Measure: A precise powder measure is critical for consistent powder charges, preventing overloads and underloads.
- Scale: An accurate scale for verifying powder charges is a must-have safety precaution.
- Bullet Seating Die: Ensures proper bullet seating depth and concentricity.
- Primer Seating Tool: For safely seating primers into prepared cases.
- Case Lubricant: Reduces friction during resizing and prevents case damage.
Step-by-Step Reloading Process
This section outlines the reloading process. Remember to always consult your reloading manual and follow all safety precautions. This data is for informational purposes only and should not be considered a substitute for reputable reloading manuals.
1. Case Preparation:
- Cleaning: Remove all residue from spent cases.
- Sizing: Resize cases to ensure consistent dimensions.
- Trimming: Trim cases to the specified length for optimal performance.
- Deburring: Remove any burrs or sharp edges from the case mouths and flash holes.
- Primer Pocket Cleaning: Ensure primer pockets are clean and free of debris.
2. Powder Charging:
- Powder Selection: Choose a powder specifically recommended for the .220 Swift. Consult reloading manuals for specific powder recommendations based on your chosen bullet weight.
- Accurate Measurement: Use your powder measure and scale to ensure consistent and accurate powder charges. Always double-check your powder charge before seating the bullet.
3. Primer Seating:
- Primer Selection: Use appropriate primers recommended for the .220 Swift.
- Careful Seating: Seat primers firmly and evenly to ensure proper ignition.
4. Bullet Seating:
- Bullet Selection: Choose bullets appropriate for your intended use and velocity.
- Consistent Seating: Ensure bullets are seated to the correct depth for optimal accuracy and to prevent exceeding safe pressure limits. Use a bullet comparator to check seating depth.
5. Final Inspection:
- Visual Inspection: Carefully inspect each round for any defects or inconsistencies.
