The 6.5x47 Lapua cartridge has gained significant popularity among precision rifle shooters and long-range enthusiasts. Its exceptional accuracy, relatively low recoil, and impressive ballistic performance make it a top choice for various shooting disciplines. However, achieving optimal performance with the 6.5x47 Lapua requires meticulous reloading practices. This comprehensive guide provides in-depth reloading data for the 6.5x47 Lapua, covering crucial aspects to ensure safety and maximize accuracy. Remember, always prioritize safety and consult your own load manuals before attempting to reload ammunition. This information is for educational purposes only.
Understanding the 6.5x47 Lapua Cartridge
Before delving into reloading data, let's briefly examine the unique characteristics of the 6.5x47 Lapua. This cartridge boasts a relatively short, efficient case design, contributing to its impressive performance. Its higher pressure capacity, compared to similar calibers, allows for higher velocities while maintaining accuracy. The 6.5mm bullet diameter also facilitates excellent ballistic coefficients, resulting in flatter trajectories and reduced wind drift.
Key Features of 6.5x47 Lapua:
- High Velocity Potential: Due to its efficient case design and high pressure handling capability.
- Flatter Trajectories: Achieved with high ballistic coefficient bullets.
- Reduced Recoil: Compared to larger calibers, making it comfortable for extended shooting sessions.
- Excellent Accuracy: Highly regarded for its precision capabilities.
- Premium Components: Often requires high-quality components for optimal results.
Reloading Components: Choosing the Right Materials
The quality of your reloading components directly impacts the accuracy and safety of your ammunition. Selecting high-quality components is paramount for optimal results with the 6.5x47 Lapua.
Essential Components:
- Brass: Lapua brass is the preferred choice by many due to its consistency and reliability. Other high-quality brands, such as Norma and Peterson, can also produce acceptable results. Avoid using mixed brass batches.
- Bullets: A wide selection of 6.5mm bullets is available, ranging from 120 grain to 160 grain. The optimal bullet choice depends on your intended application. Consider the ballistic coefficient (BC) for long-range shooting.
- Powder: Various propellants are suitable for the 6.5x47 Lapua. Popular options include Hodgdon H4350, Varget, and Reloder 17. However, powder selection is dependent on the bullet weight and desired velocity. Consult your specific powder manufacturer's load data.
- Primers: Small rifle primers are standard for this caliber. High-quality primers from reputable brands are crucial for consistent ignition and reduced variation. Avoid using improperly seated or damaged primers.

The table below presents a sample of potential 6.5x47 Lapua reloading data. These are only examples and may not be suitable for your specific equipment, components, or environment. Always start low and work your way up, meticulously observing for signs of over-pressure.
| Bullet Weight (grains) | Powder (type & grains) | Primer | COL (inches) | Avg. Velocity (fps) | Notes |
|---|---|---|---|---|---|
| 140 | H4350 (43.0) | Small Rifle | 2.820 | 2750 | Start Low, Work Up |
| 140 | Varget (42.0) | Small Rifle | 2.820 | 2700 | Start Low, Work Up |
| 147 | Reloder 17 (44.5) | Small Rifle | 2.850 | 2700 | Start Low, Work Up |
| 160 | H4350 (44.0) | Small Rifle | 2.900 | 2600 | Start Low, Work Up |
COL: Cartridge Overall Length. This measurement is critical and should be checked carefully using a case gauge.
Safety Precautions: The Importance of Safe Reloading Practices
Reloading ammunition involves working with potentially dangerous materials. Always prioritize safety and adhere to these essential precautions:
- Proper Eye and Ear Protection: Always wear safety glasses and hearing protection.
- Cleanliness: Maintain a clean and organized workspace to prevent accidents.
- Follow Instructions: Strictly adhere to instructions from your powder manufacturer and reloading manuals.
- Start Low, Work Up: Never start with maximum loads. Start with minimum loads and incrementally increase charges to find an optimal load for your rifle.
- Inspect Ammunition: Carefully inspect each cartridge for defects before loading into your firearm.
- Never Force Anything: Do not force cases into dies or bullets into cases.
Troubleshooting Common Issues in 6.5x47 Lapua Reloading
Even with careful attention, some problems may arise.
Common Problems and Solutions:
- High Pressure Signs: Flat primers, excessive case head expansion, or unusual sounds indicate over-pressure. Immediately cease loading and investigate the cause.
- Inconsistent Accuracy: This could be due to inconsistent powder charges, improper bullet seating, or a faulty rifle.
- Case Head Separation: Ensure proper case preparation and avoid excessive pressure.
Consult experienced reloaders or a gunsmith for more specific assistance with these issues.
Conclusion: Achieving Precision with 6.5x47 Lapua Reloading
The 6.5x47 Lapua cartridge offers exceptional accuracy and long-range performance. Reloading your own ammunition can significantly enhance your shooting experience, providing cost savings and the ability to fine-tune your loads for optimal results. However, safe and successful reloading requires careful attention to detail, adherence to safety guidelines, and a thorough understanding of the process. Remember to always consult your powder manufacturer’s load data and never exceed recommended maximum loads. Safe reloading and happy shooting!
