In terms of burn rate, H335 falls into the medium-burn-rate category. While the exact burn rate can vary slightly between batches, its position allows it to function well in a variety of calibers. It burns slightly slower than some faster-burning powders, offering a balance between velocity and pressure development.
The performance characteristics of H335 offer a number of advantages. It provides good consistency, making it a good choice for target shooting, where precision is paramount. Its predictable burning behavior contributes to better accuracy. Also, the ball powder’s ease of metering simplifies the reloading process, leading to more consistent results. However, like all propellants, H335 can be sensitive to temperature changes. The reloader must consider this when loading in different climates.
Ideal Applications
H335 shines in a selection of popular calibers and bullet weights. Specifically, it is a favourite amongst reloaders of the .223 Remington for both light- and medium-weight bullets. It is also employed effectively in the .308 Winchester for various bullet weights, as well as other calibers. Understanding the recommended bullet weight range for a specific cartridge will help you maximize performance and safety.
Essential Sources of Load Data
Reloading Manuals
Reliable load data is the cornerstone of safe and successful reloading. It is essential to consult and adhere to published information from trusted sources.
Reloading manuals are the primary reference for load data. These manuals, published by respected manufacturers and organizations, offer comprehensive data for a vast array of calibers, powders, and bullets. They usually include detailed instructions, diagrams, and safety precautions. Popular reloading manuals include those published by Lyman, Hornady, and Hodgdon. Each manual is carefully compiled through extensive testing and research, providing a reliable source of information.
Online Resources
Online resources provide additional avenues for accessing load data. The manufacturer’s website, such as Hodgdon’s, often contains up-to-date data. Reloading forums can also provide information, although it is important to approach these sources with caution. Always verify information found online with data from published manuals.
Importance of Verified Data
The importance of using verified data cannot be overstated. Always prioritize safety and rely on established sources when developing your loads. Cross-reference data from multiple sources when possible. If there’s any doubt, err on the side of caution and consult a qualified reloading expert. Incorrect load data can cause catastrophic failure of the firearm, risking severe personal injury or even death.
Critical Considerations for Reloading with H335
Case Preparation
Before you even begin weighing powder, thorough case preparation is the first step. This is key for safety and accuracy.
Case trimming is often necessary to ensure proper cartridge length. Trimming involves removing excess material to meet the recommended specifications for a given caliber. Case trimming provides for consistent neck tension and aids in the performance of the ammunition. Ensure you are using a case trimmer designed for your cartridge.
Chamfering and deburring the case mouth improves bullet seating and promotes consistent neck tension. Chamfering involves creating a small bevel on the inside of the case mouth, while deburring smooths any sharp edges on the outside. This process prevents damage to the bullet and case during loading.
Thorough cleaning is another vital part of case preparation. Use a case tumbler or ultrasonic cleaner to remove dirt, grime, and residue from the cases. Clean cases will help the powder burn more consistently and prevent any issues that could arise from contamination.
Primers and Bullet Selection
The selection of primers plays a crucial role in load development. The primer’s sensitivity, ignition characteristics, and the power it provides impact the overall burn rate and pressure within the cartridge. For many cartridges loaded with H335, a standard primer is sufficient. Consult your reloading manual to find the recommended primer for your caliber, bullet weight, and H335 powder charge. Some calibers might suggest a magnum primer depending on the powder charge, case capacity, and bullet type.
Bullet selection is a critical aspect that affects load data. Consider bullet weight ranges, and the type of bullet. Your choice of bullet influences the load data you will need. A lighter bullet requires a smaller powder charge than a heavier bullet. In general, H335 performs well with a range of bullet weights within the recommended parameters.
Powder Measurement and Loading Process
Precise powder measurement is vital for consistent and safe performance. Use a quality powder scale to weigh charges accurately. Digital scales provide accurate measurements, allowing you to meet your target charge. A powder dispenser can simplify the process, delivering consistent powder charges. Regular calibration of the scale is essential for reliable results.
The loading process itself involves specific considerations. Seating depth, the distance the bullet is seated into the case, affects pressure and accuracy. Follow the recommendations provided by your reloading manual.
Crimping can improve bullet retention and ensure proper chambering. Determine if crimping is necessary by consulting your reloading manual. If crimping is recommended, use a crimping die to apply the appropriate amount of crimp.
Load Data: Putting it into Practice
Let’s look at some example cartridges and illustrate how to consult and apply load data. It is vital to reiterate, these are *examples* and not instructions. Always consult your manuals and perform your due diligence.
Example Calibers and Bullet Weights
For the .223 Remington, H335 is a popular choice. The reloader may want to choose a starting charge, following the guidelines in a reloading manual. The manual would give you a powder charge range. From there, you would incrementally increase the charge, observing the cartridge for signs of overpressure. The COAL (Cartridge Overall Length) provided in the manual is also critical.
For the .308 Winchester, H335 also presents a useful option. The bullet weight selection, the primer selection, and the powder charge all need to be properly considered. The reloader will also reference the COAL, and ensure it is adhered to for both safety and function. Again, follow the recommendations in your manual.
Remember that these examples are merely meant to illustrate how to find and apply load data. Always consult your chosen reloading manual for the complete data. The data will include starting and maximum charges, recommended primers, and COAL for each specific bullet and caliber.
