Optimizing Performance with Sierra Bullet Reloading Data
Achieving the best accuracy and performance involves fine-tuning your loads:
Tips for Optimization:
- Start Low, Work Up: Begin with the minimum charge listed in Sierra’s data and gradually increase until optimal accuracy is achieved.
- Maintain Consistency: Use the same brand and lot of powder, and measure charges meticulously.
- Adjust Seating Depth: Slight variations can impact accuracy; experiment within safe limits.
- Check for Signs of Excessive Pressure: Flattened primers, case elongation, or sticky bolt lift indicate overpressure.
Load Development Process:
1. Develop a ladder of loads around the starting load.
2. Test each load at the range, recording group sizes and velocity.
3. Identify the load that offers the best accuracy with safe pressure signs.
4. Fine-tune seating depth and powder charge as needed.
