The 22-250 Ackley Improved (AI) cartridge is a favorite among long-range shooters and varmint hunters for its impressive accuracy and flat trajectory. However, achieving optimal performance requires meticulous attention to reloading details. This guide provides comprehensive 22-250 AI load data, emphasizing safety and accuracy. Remember, always prioritize safety and consult your specific reloading manual before attempting any reloading. This information is for educational purposes only.
Understanding the 22-250 Ackley Improved
The 22-250 AI is a modified version of the standard 22-250 Remington. The improved version features a sharper shoulder angle, allowing for increased case capacity and higher velocity. This translates to flatter trajectories and increased effective range, making it ideal for long-range shooting applications. However, the increased pressure necessitates careful attention to reloading parameters to avoid dangerous over-pressures.
Key Considerations for 22-250 AI Reloading
Before diving into specific load data, let's address critical aspects impacting your reloading results:
1. Case Preparation:
- Neck Turning: Essential for consistent neck tension and improved accuracy. Variations in neck thickness can significantly affect bullet seating depth and pressure.
- Primer Pocket Uniformity: Ensure consistent primer seating depth to prevent misfires or excessive pressure.
- Case Trimming: Maintain consistent case length to avoid excessive headspace and potential pressure issues. Regular trimming is crucial, especially with repeated firings.
2. Bullet Selection:
Bullet choice significantly impacts accuracy and ballistic performance. Consider factors such as:
- Weight: Heavier bullets generally offer better ballistic coefficients (BC) for longer-range accuracy, but may require more powder.
- Profile: The bullet's shape affects its aerodynamic characteristics and stability in flight. Match your bullet to your intended application. Consider ballistic tips for enhanced long-range performance.
- Construction: Choose a bullet construction suitable for your intended game or target.
3. Powder Selection:
Powder selection is crucial for achieving optimal performance and safety. Experimentation is necessary to find the best powder for your specific rifle and components. Popular choices for 22-250 AI include:
- Hodgdon Varget: Known for its versatility and excellent accuracy in a wide range of cartridges.
- IMR 4350: Another popular choice offering good accuracy and consistent performance.
- RL-15: A well-regarded powder known for its consistent performance in high-velocity cartridges.
Always consult your reloading manual for recommended powder charges and other specific data for your chosen powder.
4. Primer Selection:
Small rifle primers are standard for the 22-250 AI. Use a quality primer from a reputable manufacturer.
Sample Load Data (Illustrative Only - Not a Substitute for Your Manual)
Disclaimer: The following data is for illustrative purposes only. It's crucial to consult your reloading manual and conduct thorough research before attempting any loads. This information does not constitute a recommendation and should never be considered a replacement for safe reloading practices. Improper loading can lead to dangerous over-pressures and catastrophic equipment failure.
| Bullet Weight (grains) | Powder (type) | Powder Charge (grains) | Primer | COL (inches) | Notes |
|---|---|---|---|---|---|
| 50 | IMR 4350 | 38.0 | Small Rifle | 2.260 | Start low, work up |
| 55 | Hodgdon Varget | 39.0 | Small Rifle | 2.270 | Start low, work up |
| 55 | RL-15 | 36.5 | Small Rifle | 2.250 | Start low, work up |
Remember to always start at the minimum charge listed in your reloading manual and work your way up gradually, carefully observing for any signs of excessive pressure.
Safety First: Crucial Reloading Practices
- Start low and work up: Never start at maximum recommended loads. Gradually increase powder charges in small increments while carefully monitoring pressure signs.
- Use a calibrated scale: Accurate powder measurement is critical for consistent performance and safety.
- Inspect cases and components: Check for any damage or defects before loading.
- Never mix powders: Using the wrong powder can lead to catastrophic failure.
- Use proper safety gear: Eye protection and hearing protection are essential.
- Store ammunition properly: Keep ammunition in a cool, dry place, away from sources of ignition.
This comprehensive guide provides a strong foundation for safe and effective 22-250 AI reloading. Always remember to consult your reloading manual and prioritize safety above all else. Enjoy the precision and power this fantastic cartridge offers!
