IMR 4064 is a popular, versatile propellant known for its excellent performance in a wide range of cartridges. However, safe and accurate reloading with IMR 4064 requires careful attention to detail and adherence to reputable load data sources. This guide provides comprehensive information on using IMR 4064, emphasizing safety and precision. Always prioritize safety and consult multiple sources before attempting any reloading. This information is for educational purposes only and should not be considered a substitute for professional reloading instruction.
Understanding IMR 4064's Characteristics
IMR 4064 is a medium-burning, extruded powder known for its relatively low pressure and consistent performance. Its versatility makes it suitable for various calibers and bullet weights, from varmint rounds to heavier hunting cartridges. However, its sensitivity to temperature and variations in lot-to-lot consistency necessitates careful attention to detail during the reloading process.
Key Properties:
- Medium-Burning Rate: This contributes to its versatility across different cartridge types.
- Extruded Powder: Offers consistent burn characteristics compared to ball powders.
- Temperature Sensitivity: Performance can be affected by extreme temperatures, emphasizing the importance of consistent storage and loading conditions.
- Lot-to-Lot Variation: While generally consistent, slight variations between powder lots may occur.
Finding Reliable IMR 4064 Load Data
The most crucial aspect of safe reloading is using accurate and reliable load data. Never deviate from published load data, unless you have extensive experience and understand the potential risks.
Reputable Sources:
- Hodgdon Powder Company: As the manufacturer of IMR 4064, Hodgdon provides official load data on their website. This should be your primary source.
- Reloading Manuals: Several reputable publishers produce comprehensive reloading manuals containing extensive load data for various cartridges and powders, including IMR 4064. Look for manuals from well-established publishers with a strong reputation for accuracy.
- Loading articles from reputable gun publications: Some shooting and reloading magazines provide load data developed by experienced reloaders and often tested under controlled conditions.
Factors to Consider When Choosing Load Data:
- Caliber and Cartridge: Ensure the data is specific to your cartridge.
- Bullet Weight and Type: Different bullet weights and types affect pressure and velocity.
- Primer Type: The type of primer can influence ignition characteristics.
- Case Length: Variations in case length can impact pressure.
- Powder Lot Number: Ideally, use the specific powder lot number indicated in the data source for optimal results.
Safe Reloading Practices with IMR 4064
Safe reloading requires meticulous attention to detail and adherence to established procedures. Always follow these safety practices:
- Wear Safety Glasses: Protect your eyes from potential hazards.
- Work in a Well-Ventilated Area: Powder dust can be irritating and potentially harmful.
- Use a Reloading Scale: Accurately measure powder charges for consistent results and safety.
- Avoid Static Electricity: Static electricity can cause powder to ignite unexpectedly.
- Never Force Anything: If a component doesn't fit properly, investigate the cause before proceeding.
- Clean Your Equipment Regularly: Maintain your reloading equipment for optimal performance and safety.
- Start Low and Work Up (Gradually): Begin with the minimum charge listed in your chosen load data and gradually increase to the maximum only after careful monitoring.
Understanding the Importance of Accurate Measurement
Using a reloading scale to measure powder charges is essential for both safety and accuracy. Inconsistent powder charges can lead to variations in pressure, potentially causing dangerous conditions or inaccurate performance.
