The .460 Rowland is a potent cartridge known for its impressive stopping power, making it a popular choice for self-defense and competitive shooting. However, reloading this powerful round requires precision and a deep understanding of safe loading practices. This guide provides comprehensive information on 460 Rowland reloading data, emphasizing safety and accuracy. Always prioritize safety and consult your reloading manual before attempting any reloading. This information is for educational purposes only and should not be considered a substitute for professional guidance.
Understanding the .460 Rowland Cartridge
The .460 Rowland, designed by renowned firearms expert Richard Rowland, is a powerful cartridge built on the 10mm Auto case. Its increased capacity and higher pressures result in significantly greater velocity and energy compared to the 10mm. This power necessitates careful attention to detail when reloading. Variations exist in case dimensions, even within the same manufacturer, so accurate case measurement is crucial.
Key Considerations Before Reloading:
- Proper Equipment: Invest in high-quality reloading equipment, including a scale capable of precise measurements (to the tenth of a grain), case trimmer, powder measure, and appropriate dies.
- Reliable Components: Use only high-quality bullets, primers, and powder specifically designed for the .460 Rowland. Using substandard components can lead to catastrophic failure.
- Safety Gear: Always wear safety glasses and hearing protection when reloading. Consider using a reloading bench with a bullet-trapping system.
- Reference Manuals: Consult multiple reputable reloading manuals from sources such as Hodgdon, Alliant, and Accurate Arms. Never rely solely on online data. Cross-referencing data from multiple sources is key to ensuring safety and accuracy.
- Start Low and Work Up: Always start with the minimum recommended load from your chosen reloading manual and gradually increase the powder charge while carefully monitoring pressure signs.
- Observe Pressure Signs: Familiarize yourself with signs of excessive pressure, such as flattened primers, excessively hard bolt lift, or unusual noises. If you observe any of these, immediately cease reloading and consult a reloading expert.
460 Rowland Reloading Data Sources and Considerations
Finding reliable 460 Rowland reloading data can be challenging due to the cartridge's relatively recent introduction. However, several reputable sources exist:
- Hodgdon Powder Company: Hodgdon provides extensive reloading data for a variety of cartridges, and while they may not specifically list the .460 Rowland, their data for similar cartridges can offer guidance. Remember to always adjust loads cautiously and carefully consider the differences in pressure and case capacity.
- Alliant Powder: Similar to Hodgdon, Alliant offers detailed reloading information that can serve as a reference point. Always prioritize safe loading practices.
- Accurate Arms: Another reputable powder manufacturer, Accurate Arms, often publishes data for less common cartridges. Consulting their resources can be beneficial, but again, cross-referencing data is recommended.
- Online Forums and Communities: Online forums dedicated to reloading can provide valuable insights and experience from other reloaders. However, exercise caution and verify information with reputable sources before implementing any data. Remember that personal anecdotes should not substitute for data from reputable sources.
Data Points to Consider:
When referencing reloading data, pay close attention to these key elements:
- Bullet Weight: The weight of the bullet significantly impacts the necessary powder charge. Heavier bullets generally require more powder.
- Powder Type: Different powders burn at different rates, influencing pressure and velocity. Carefully choose a powder appropriate for the .460 Rowland and the specific bullet weight you are using.
- Primer Type: While less influential than bullet weight and powder type, the primer can still have a minor effect on pressure.
- Case Length: Ensure consistent case length through trimming. Variations in case length can affect pressure.
Safety First: A Recap
Reloading the .460 Rowland demands precision and meticulous attention to detail. Failure to adhere to proper safety procedures can result in serious injury or damage to your firearm. Remember these crucial safety points:
- Start low and work up.
- Always use a reliable reloading manual.
- Observe pressure signs carefully.
- Never exceed the maximum recommended load.
- Use high-quality components.
- Maintain clean and properly functioning equipment.
This guide provides a foundation for safe and accurate 460 Rowland reloading. However, it's crucial to reiterate that this information should not replace thorough research and consulting reputable reloading manuals and experienced reloaders. Safe reloading practices are paramount. Always prioritize safety above all else.
