Finding the right powder bushing is crucial for consistent and safe reloading. Hodgdon, a trusted name in reloading components, offers a wide variety of powder bushings for their powder measures. However, navigating the selection process can be confusing without a readily available chart. While a readily downloadable PDF isn't consistently offered directly by Hodgdon, this guide provides the information you need to understand and utilize their bushing system effectively. We'll cover how to find the right bushing for your needs and explain the importance of accurate powder charges in reloading.
Understanding Hodgdon Powder Bushings
Hodgdon powder bushings are small, precisely-machined components that control the amount of powder dispensed by their powder measures. Each bushing has a specific hole size, dictating the volume of powder delivered per throw. The key to accurate reloading lies in selecting the correct bushing for your chosen cartridge and powder type. Using the wrong bushing can lead to unsafe loads, inconsistent performance, and potential damage to your firearm.
Why a Chart Isn't Always Available (and What to Do Instead)
While a single, all-encompassing PDF chart for all Hodgdon powder bushings and their corresponding powder charges doesn't exist on their website, this isn't unusual for reloading equipment manufacturers. This is because the optimal bushing size is dependent not just on the powder type, but also on factors like the specific powder measure model and even variations in powder manufacturing batches.
Instead of relying solely on a PDF chart, Hodgdon recommends utilizing their reloading data. This data, accessible on their website (though I can't provide links here), specifies the recommended powder charge weight for various cartridges and powders. This is the most reliable and up-to-date information available. You then use this weight to determine the appropriate bushing size through careful measurement and testing.
Determining the Correct Bushing Size: A Step-by-Step Process
-
Consult Hodgdon's Reloading Data: This is your primary source. Find the data specific to your chosen cartridge and powder. Note the recommended powder charge weight.
-
Select Your Powder Measure: Make sure you know the exact model of your Hodgdon powder measure. Different models might use different bushing systems.
-
Begin with a Trial Bushing: Start with a bushing size that's close to the expected weight. Many reloaders start with a middle-of-the-road size and adjust from there.
-
Measure and Adjust: Dispense several powder charges (at least 5-10) using the chosen bushing. Weigh each charge individually using a precision scale. Compare the average weight to the recommended weight from Hodgdon's data.
-
Iterative Refinement: If the average weight is too high, try a smaller bushing. If it's too low, try a larger one. Repeat steps 4 and 5 until you achieve an average weight that closely matches the recommended weight.
-
Maintain Records: Keep a meticulous log of your findings, noting the powder type, cartridge, bushing size, and average weight per charge. This log is invaluable for future reloading sessions.
Safety First: Critical Considerations for Reloading
- Always use a scale: Never rely solely on the bushing to determine powder charge weight. A precise scale is essential for safety and accuracy.
- Double-check your work: Always verify your powder charge before loading it into a cartridge case.
- Consult reloading manuals: Use only reloading data from trusted sources like Hodgdon. Never exceed the maximum recommended charge weight.
- Regular maintenance: Keep your powder measure clean and properly lubricated for optimal performance.
By following these steps and prioritizing safety, you can confidently use your Hodgdon powder measure to create precise and safe ammunition. Remember that consistency and accuracy are paramount in reloading. The lack of a readily available PDF chart shouldn't deter you from safe and effective reloading practices. Focus instead on using the precise and reliable data provided by Hodgdon.
