Understanding Hodgdon Powder and Reloading
Before we delve into the chart, it’s essential to grasp the fundamentals of Hodgdon powder and the broader reloading process. Hodgdon powders are meticulously manufactured and extensively tested, designed to deliver consistent performance across a wide range of calibers and applications. Each powder type has specific burning characteristics, influencing the pressure and velocity generated within a cartridge when ignited. Choosing the right powder is therefore critical for achieving the desired ballistic results and maintaining safe operating pressures within your firearms.
The reloading journey typically involves a series of steps, each demanding meticulous attention. It starts with inspecting and preparing spent cartridge cases, followed by resizing and priming them. Then, comes the crucial task of adding the precise amount of powder. Next, bullets are carefully seated within the case, and finally, the loaded cartridge is crimped to secure the bullet and ensure consistent ignition. Throughout this process, using the correct tools and following the proper procedures is paramount. A good reloading setup usually includes a scale to measure components, a powder measure, dies, and case trimmers.
What is a Hodgdon Powder Bushing Chart?
The foundation of safe and effective reloading hinges on the precise measurement of gunpowder. Too little powder can lead to inconsistent performance or even failure to fire, while excessive amounts can generate dangerously high pressures, causing damage to your firearm and posing a significant risk of injury. This is where the importance of the Hodgdon Powder Bushing Chart comes into play.
A powder bushing chart is a fundamental tool designed to assist reloaders in selecting the appropriate bushing size for a specific powder and desired powder charge. Bushings are essentially cylindrical inserts used within powder measures, designed to meter a predetermined volume of powder with each throw. By using the chart, reloaders can quickly identify the optimal bushing for a given powder and the targeted powder charge they want to achieve.
The chart isn’t merely a collection of random numbers; it is a carefully compiled reference that allows you to correlate the bushing number with the amount of a specific powder that will be dispensed. The chart is often organized by powder type, with each powder listed alongside a selection of bushings and the corresponding charge weights they are likely to produce when used within a specific powder measure.
It’s important to understand that the chart represents estimations. There can be variations in the actual charge weight due to various factors, like how the bushing is seated, the consistency of the powder lots, and the type of powder measure being used. The chart’s primary function is to give you a starting point for adjusting your powder measure to throw the desired charge. Therefore, it’s a great way to save time when you are setting up a new load.
Downloading and Accessing the Hodgdon Powder Bushing Chart PDF
Acquiring access to the Hodgdon Powder Bushing Chart PDF is a straightforward process. The official Hodgdon website is the primary source for these crucial tools. By visiting the website, you’ll typically find a dedicated section for reloading information and resources. From there, you should be able to easily locate the Hodgdon Powder Bushing Chart PDF for download. Once downloaded, the chart is ready to be used.
The available charts are often in PDF format, making them easy to access and print. Ensure you always download the most recent version of the chart. Hodgdon regularly updates these resources to reflect changes in powder formulations, testing methodologies, or any new powders introduced.

How to Use the Hodgdon Powder Bushing Chart
Using the Hodgdon Powder Bushing Chart requires a methodical approach. Here’s a step-by-step guide:
The first step is identifying the exact powder you plan to use. Locate the correct powder on the chart. Hodgdon often categorizes its powders by name (e.g., H4895, Varget, Titegroup).
Next, find the type of powder. Identify the powder type. Is it a flake powder, a ball powder, or an extruded powder? The type will help refine the chart findings.
Once you’ve identified your specific Hodgdon powder, examine the chart’s columns to find the bushing size that corresponds to your targeted powder charge. The charge weights listed in the chart are generally based on average measurements using standard powder measures. Keep in mind the chart is only a reference, and it’s always a good idea to double-check with a weighing scale.
Always cross-reference the bushing chart with a reliable reloading manual that provides load data specific to your cartridge and bullet combination. Reloading manuals, such as those published by Hornady, Lyman, or Sierra, offer carefully tested and validated load recipes. These manuals should always be considered the primary source for load data. Compare the suggested powder charge from your reloading manual with the chart’s recommended bushing size.
Begin with the lowest recommended charge listed in your reloading manual, especially when you are reloading a new caliber or bullet configuration. Start by adjusting your powder measure to throw the powder charge suggested by the Hodgdon Powder Bushing Chart PDF and by your reloading manual.
After the correct bushing and charge are selected, the charges need to be weighed on a scale. Then, start by throwing a powder charge into your powder measure. After, weigh the powder charge that it throws.
The Hodgdon Powder Bushing Chart provides excellent information for the powder measure, but the scale is still the most important tool. When starting out, you should weigh every charge.
Important Considerations and Tips for Accurate Powder Measurement
In the realm of reloading, safety is not just a recommendation; it’s a non-negotiable imperative. Always wear safety glasses to protect your eyes from stray powder grains, potential case ruptures, or ejected primers. Handle and store your powders with care, following the manufacturer’s instructions. Avoid smoking, open flames, and any potential sources of ignition near your reloading bench. Finally, never exceed the maximum powder charges specified in your reloading manual. Overloading a cartridge can have severe consequences, leading to firearm damage or, even worse, serious injury.
Numerous factors can subtly influence the powder charge dispensed by your powder measure. Powders from different production lots, even those of the same type, may have slight variations in density. Temperature and humidity can also affect the volume of powder dispensed. Moreover, variations in equipment, like the design of the powder measure, can introduce minor differences.
While the Hodgdon Powder Bushing Chart serves as a reliable guide, the importance of weighing each powder charge for consistency cannot be overstated, particularly when you’re still learning the ropes of reloading or working with a new powder or cartridge combination. Weighing each charge will help you quickly identify any potential issues and ensure that every round you load is within safe and consistent parameters.
Troubleshooting and Common Issues
When you discover that the chart doesn’t perfectly match the desired powder charge for a load, use the chart as a starting point and work to refine the charge with your scale. You might need to adjust the bushing slightly to make sure you get the proper weight. Increase the powder charge in small increments.
Even with the best techniques, some issues might emerge during the reloading process. Powder leakage is a common problem. Ensure all the components fit properly and the powder measure is seated securely. Inconsistent powder charges are another possibility. To deal with this, check the consistency of the powder and ensure the bushing is correctly chosen for your process.
Where to Buy and Maintain Powder Bushings
Purchasing powder bushings is a relatively easy process. Online retailers specializing in reloading supplies are a good place to start, where you’ll find a wide selection of bushings. Local gun stores with reloading sections usually carry bushings, providing you with an opportunity to consult with experienced reloaders and assess the fit and finish of the bushings before purchasing.
Maintain your bushings by regularly cleaning them to ensure smooth and consistent powder flow. Always store your bushings in a dry, secure location. This practice will extend their lifespan and ensure their functionality.
