Starting Loads and Gradual Work-Up
This section does not provide specific loading data. It is absolutely crucial to consult Hornady's official reloading manual for the most up-to-date and accurate load data for the specific bullets and powders you are using. Hornady's manuals are readily available online and through their website.
The process of working up a load involves starting with the minimum recommended charge from the manual and gradually increasing it in small increments (0.1-0.2 grains at a time), carefully observing pressure signs throughout the process. These signs include excessive primer flow, flattened primers, sticky bolt lift, and unusual sounds during firing. If you observe any of these signs, immediately cease increasing the charge and consult the Hornady manual for further guidance.
Key Considerations for Safe and Accurate Reloading
- Weighing Charges: Always use a precise powder scale to ensure accurate powder charges. Inconsistent powder charges can lead to erratic performance and pressure issues.
- Proper Case Preparation: Properly clean, deprime, and resize your brass before reloading. Consistent case preparation is vital for consistent results.
- Consistent Seating Depth: Maintain consistent bullet seating depth for optimal accuracy. Use a bullet seating die with a micrometer adjustment for precise control.
- Record Keeping: Meticulously record all your reloading data, including bullet weight, powder type and charge, primer type, and overall cartridge length. This is essential for future reference and troubleshooting.
- Safety Equipment: Always wear safety glasses and hearing protection when reloading and shooting.
This guide provides a framework for safely and effectively reloading 7mm Remington Magnum ammunition using Hornady components. Remember, safety is paramount. Always consult Hornady's official reloading manuals for precise loading data and strictly adhere to their recommendations.
