Understanding the 7mm-08 Remington and the Hornady 139 gr SST
The 7mm-08 Remington is a popular cartridge known for its accuracy, moderate recoil, and flat trajectory. Its versatility makes it suitable for various hunting applications, from varmints to larger game. The Hornady 139 gr SST (Super Shock Tip) bullet is a popular choice for its excellent accuracy and expansion characteristics, making it a great option for hunting deer-sized game.
Key Considerations Before Reloading
Before you begin, ensure you have the necessary tools and equipment, including a reloading press, dies, powder scale, and case trimmer. Accurate measurements are paramount for safety and consistency.
- Consult Multiple Sources: Never rely on a single source for reloading data. Always cross-reference information from multiple reputable manufacturers, such as Hornady, to ensure accuracy and safety.
- Start Low and Work Up: Begin with the minimum powder charge listed in your chosen data source and work your way up in small increments, carefully observing pressure signs.
- Observe Pressure Signs: Pay close attention to pressure signs during loading and shooting. Excessive pressure can lead to dangerous situations. Signs include flattened primers, excessive case head expansion, or unusually high chamber pressure.
- Proper Case Preparation: Ensure your brass is clean, sized correctly, and trimmed to the appropriate length before loading.
