Safety First: Reloading Best Practices
Reloading ammunition is a rewarding pursuit that allows shooters to customize their loads, save money, and enhance their accuracy. However, it is a process that demands respect and a firm commitment to safety.
First and foremost, you need the right equipment. The essential tools include a reloading press, reloading dies, a precision scale for accurately measuring powder charges, a powder measure, calipers for precise measurements of cartridge length and case dimensions, case trimmers, and a bullet seating tool. Investing in quality equipment will not only improve the safety of the process but also lead to better results.
Your workspace should be well-lit and well-ventilated. Always wear eye protection to shield your eyes from flying debris. Gloves can provide added protection. Having a safe, dedicated workspace will minimize distractions and help maintain focus on the task at hand.
*Crucial Reminder: * The most important rule is to use published load data from reputable sources, such as the Hornady reloading manual, or well-regarded reloading manuals. Never, under any circumstances, exceed the maximum powder charge specified in the published data. Always start with the minimum recommended charge and work your way up incrementally, carefully observing for signs of excessive pressure.
Signs of overpressure can be subtle. Look for flattened primers, hard bolt lift, cratering around the firing pin, or difficult case extraction. If any of these signs appear, immediately stop reloading and consult a knowledgeable reloader or seek professional guidance.
The choice of powder and primers is critical. The burn rate of the powder must be appropriate for the .308 Winchester and the 150-grain bullet. Powders like IMR 4064, Varget, and Reloder 15 often work well with this combination. The right primer can also affect the ignition. The primer’s sensitivity and ignition strength can have a direct impact on the load’s consistency and accuracy.
Before loading, check your brass, trimming and preparing the cases to the correct length is crucial for safety and optimal performance.
Load Data Considerations
*Disclaimer:* The information below is provided as an example and *must not* be used without cross-referencing with reliable reloading manuals and Hornady’s published data. Always start with the lowest recommended powder charge and increase cautiously, observing carefully for signs of excessive pressure.
When working with Hornady 308 150 Grain Load Data, consider the following factors, which contribute to the overall safety and effectiveness:
The Specific Bullet Type
The specific Hornady bullet you’re using (e.g., SST, InterLock, ELD-M) will influence the load data. Always consult the reloading manual for the specific bullet.

The OAL is a critical dimension. It significantly affects pressure and can influence accuracy.
Accuracy and Testing
Accurate shooting relies on more than just the right Hornady 308 150 Grain Load Data. Proper sighting-in of your rifle is the starting point. Zeroing your scope at a specific distance (e.g., 100 yards) allows you to confidently engage targets at various ranges.
Understanding how to interpret group sizes is essential. Smaller groups, with all shots clustered together, indicate better accuracy. Several factors affect accuracy. The condition of your rifle’s barrel (a dirty barrel can significantly degrade accuracy). The environment (wind, temperature, and humidity).
Consistency is king when it comes to reloading. The consistency of the powder charge, seating depth, and crimp will all impact accuracy. Small variations can lead to significant changes in trajectory and impact point.
Testing loads is critical. Start by loading several rounds with a specific powder charge and then firing them at a target. Record the group size, velocity, and any observations of pressure. Experiment with increasing the powder charge in small increments, always carefully monitoring for signs of overpressure.
