Their approach prioritizes safety and accuracy, rigorously testing various powder charges, bullet weights, and primers to optimize performance and ensure consistent results. The data provided in their manuals is the result of extensive testing and should be followed precisely.
Key Considerations Before Reloading
Before diving into specific Nosler load data for the 7mm Rem Mag, remember these critical safety precautions:
- Consult the Manual: Always refer to the most current edition of the Nosler Reloading Manual. This is your primary source for accurate and safe load data. Never rely on information found elsewhere without verifying it against the manual.
- Proper Equipment: Ensure you have the necessary reloading equipment, including a scale accurate to 0.1 grain, case trimmer, and appropriate dies.
- Safety Gear: Always wear safety glasses and hearing protection when reloading.
- Cleanliness: Maintain a clean and organized reloading bench to prevent mistakes.
- Start Low, Work Up: Begin with the minimum charge listed in the Nosler manual and work your way up gradually, carefully observing pressure signs at each increment. Never exceed the maximum listed charge.
- Accurate Measurement: Precise measurement is paramount in reloading. Use a scale to measure powder charges accurately.
Deciphering Nosler's 7mm Rem Mag Load Data
Nosler's load data typically includes the following information for each load:
- Bullet: Bullet weight, type (e.g., Partition, AccuBond), and ballistic coefficient (BC).
- Powder: Type and weight in grains.
- Primer: Type (e.g., large rifle magnum).
- OAL (Overall Length): The total length of the loaded cartridge.
- Velocity (fps): Expected muzzle velocity.
- Pressure (PSI): Maximum pressure observed during testing.
Important Note: The specific loads available will vary depending on the Nosler manual edition and the available bullet weights.
Interpreting Pressure Signs
While Nosler provides pressure data, learning to identify pressure signs is crucial for safe reloading. These include:
