The 6.5x55 Swedish Mauser cartridge, a venerable round with a rich history, continues to be a favorite among hunters and target shooters alike. Its inherent accuracy and mild recoil make it a pleasure to shoot, but realizing its full potential requires careful handloading. This guide dives deep into 6.5x55 load data, offering insights for both beginners and experienced reloaders. Remember, always prioritize safety and consult your own reloading manuals before attempting any reloading. This information is for educational purposes only and should not be considered a substitute for professional advice.
Understanding the 6.5x55 Cartridge
Before diving into load data, it's crucial to understand the 6.5x55's characteristics. This cartridge, also known as the 6.5x55mm Swedish Mauser, is a classic bottleneck design known for its excellent ballistic properties. Its relatively lightweight bullet coupled with a moderate powder charge provides a flat trajectory and manageable recoil. However, its older design can be sensitive to variations in powder and components, hence the need for meticulous reloading practices.
Key Components for Reloading 6.5x55
Successful reloading hinges on the quality of your components. Selecting the right bullets, cases, primers, and powder is paramount.
1. Bullets:
Bullet weight and type significantly impact ballistics. Popular bullet weights range from 120 grains to 160 grains. Bullet types include:
- Full Metal Jacket (FMJ): Ideal for target practice due to their consistent performance and affordability.
- Soft Point (SP): Offer good expansion for hunting applications.
- Boat Tail (BT): Improve ballistic coefficient, leading to flatter trajectories and longer ranges.
- Controlled Expansion (CE): Designed for consistent expansion on game, minimizing over-penetration.
2. Cases:
Choose high-quality brass cases, preferably once-fired, for consistent performance and longevity. Proper case preparation, including cleaning, resizing, and trimming, is essential for optimal accuracy.
3. Primers:
Select primers appropriate for your chosen powder and load data. Always follow the manufacturer's recommendations.
4. Powder:
Numerous powders work well with the 6.5x55. Popular choices include IMR 4350, IMR 4895, H4350, and RL19. Always consult your reloading manual for specific powder recommendations and load data. Using the wrong powder can lead to dangerous overpressure.

Safety First: Essential Reloading Practices
- Always wear safety glasses: Eye protection is crucial during the entire reloading process.
- Work in a well-ventilated area: Powder fumes can be harmful.
- Never mix powders: Use only one type of powder per loading session.
- Clean your equipment regularly: This ensures consistent performance and accuracy.
- Double-check your work: Carefully inspect each round before loading it into your firearm.
- Start low and work up gradually: This is the best way to determine the optimal load for your firearm.
- Observe pressure signs: Pay close attention to signs of overpressure, such as flattened primers or excessive case expansion.
Conclusion
Reloading 6.5x55 ammunition can be a rewarding experience, providing shooters with customized loads tailored to their specific needs and preferences. However, it's essential to approach reloading with caution, thoroughness, and a deep respect for safety. By following established procedures and adhering to manufacturer recommendations, reloaders can safely and successfully enjoy the precision and versatility this classic cartridge offers. Always remember that safe reloading practices are paramount, and consulting multiple reputable sources before attempting any reloading is crucial.
