The 6.5 x 55 Swedish Mauser cartridge, a venerable round with a rich history, continues to be a favorite among hunters and target shooters. Its accuracy, moderate recoil, and flat trajectory make it a compelling choice. However, achieving optimal performance requires meticulous reloading practices. This guide provides comprehensive 6.5 x 55 reloading data, emphasizing safety and precision. Disclaimer: Always consult your firearm's manual and follow all safety precautions before reloading ammunition. The data provided here is for informational purposes only and should not be considered a substitute for professional advice.
Understanding Your Components: The Foundation of Accurate Reloading
Before diving into specific data, let's review the critical components involved in 6.5 x 55 reloading:
1. Cases: Preparing for Precision
Proper case preparation is paramount. This includes:
- Cleaning: Remove all traces of previous primer compounds and fouling. A thorough cleaning ensures consistent ignition and prevents pressure spikes.
- Sizing: Sizing dies resize the case to the correct dimensions, ensuring consistent chambering and preventing pressure issues. Using the appropriate die for your specific sizing needs is crucial. Full-length sizing should be employed for most cases, but neck sizing might be an option if you're working with brass that’s already been fired in your specific rifle and isn't experiencing excessive runout.
- Trimming: Consistent case length is vital for accurate and safe reloading. Trimming ensures uniform case length, preventing inconsistent pressure and potential damage.
2. Primers: The Spark of Ignition
Primer selection affects ignition consistency and overall performance. Choose a primer appropriate for your powder type and environmental conditions. Small rifle primers (SRPs) are commonly used for the 6.5 x 55. Always ensure primers are seated correctly to avoid misfires or squibs.
3. Powder: The Heart of the Cartridge
Powder selection significantly impacts the cartridge's performance. Various powder types are suitable for the 6.5 x 55, each offering a distinct burn rate and pressure curve. Experimentation (within safe limits and starting with minimum loads) is crucial to find the ideal powder for your specific rifle and desired performance. Never exceed maximum recommended loads.
Popular powders for 6.5 x 55 reloading often include:
- IMR 4350: A very popular choice known for its consistent performance.
- IMR 4831: Another reliable choice, providing good accuracy and velocity.
- H4895: A versatile powder suitable for various cartridges, including the 6.5 x 55.
- RL-19: A slower-burning powder option that often provides excellent accuracy at longer ranges.
(Note: Powder selection is highly dependent on your specific bullet weight and rifle, thus thorough research into which powder is best suited to your components is highly advised)
4. Bullets: Achieving Accuracy
Bullet selection influences accuracy, trajectory, and ballistic performance. The weight and design of your bullet will significantly affect your reloading data. Popular bullet weights range from 120 grains to 160 grains, each providing a different combination of velocity and trajectory.

Safety First: Essential Precautions
- Always wear safety glasses and hearing protection.
- Work in a well-ventilated area.
- Never exceed maximum recommended loads.
- Inspect your cases, primers, and bullets for any defects before reloading.
- Keep your powder dry and away from ignition sources.
- Use a reloading scale to accurately measure powder charges.
- Consult multiple reloading manuals to cross-reference data.
Further Resources: Expanding Your Knowledge
This guide provides a foundation for safe and effective 6.5 x 55 reloading. However, further research is crucial. Consult reputable reloading manuals, such as those published by Hodgdon, Alliant, and Sierra Bullets, for comprehensive data specific to your chosen components. Engage with experienced reloaders and participate in online forums to learn from their expertise.
By combining careful preparation, precise measurements, and a commitment to safety, you can achieve accurate and reliable 6.5 x 55 ammunition tailored to your specific needs. Remember, the key to success lies in responsible and informed reloading practices.
