Alliant Powder's 20/28 is a popular choice among reloaders, known for its versatility and performance across various handgun and rifle cartridges. This comprehensive guide delves into the characteristics, applications, and considerations for using Alliant 20/28 powder. We'll explore its suitability for different calibers, discuss optimal loading data, and address common questions regarding its use.
Understanding Alliant 20/28's Properties
Alliant 20/28 is classified as an extruded powder, meaning it's formed into cylindrical grains through a process of extrusion. This contributes to its consistent burn rate and relatively low flash. Its medium burn rate makes it adaptable to a wide range of applications, from handgun loads requiring moderate pressure to certain rifle cartridges. The exact burn rate and performance characteristics can vary slightly depending on the lot number, emphasizing the importance of always consulting current reloading manuals for precise data.
Key Characteristics:
- Medium Burn Rate: Suitable for a broad spectrum of cartridges.
- Extruded Grains: Contributes to consistent burning and reduced flash.
- Versatile Applications: Useful for both handgun and rifle cartridges.
- Good Accuracy Potential: Many reloaders report high accuracy with 20/28.
- Moderate Pressure Levels: Generally considered a safe powder for proper loading.
Alliant 20/28 Applications: Handgun and Rifle Cartridges
The versatility of Alliant 20/28 makes it a favorite among reloaders for its adaptability to various calibers. However, it's crucial to understand that not all cartridges benefit equally from its characteristics.
Handgun Applications:
Alliant 20/28 excels in many popular handgun cartridges, providing reliable performance and consistent accuracy. Some examples include:
- .38 Special: Ideal for target shooting and plinking loads.
- .357 Magnum: Suitable for moderate loads, offering a good balance between power and recoil.
- 9mm Luger: Provides reliable performance in this widely used cartridge.
- .40 S&W: Can be used for target loads, but higher-pressure applications might require a faster-burning powder.
- .45 ACP: Suitable for target and moderate-pressure loads.
Rifle Applications:
While primarily a handgun powder, Alliant 20/28 finds use in some rifle applications, particularly those requiring moderate pressure levels. However, caution is advised; always consult a reloading manual specific to your chosen cartridge and powder for safe and accurate load data. Some examples include:
- .223 Remington/.556 NATO: Can be used for lighter loads, but other powders might be better suited for higher-velocity applications.
- .30 Carbine: Suitable for certain applications, but again, consult appropriate loading manuals.
Safety Precautions and Best Practices
Reloading is an inherently dangerous activity if not undertaken with meticulous care and attention to detail. Always adhere to the following safety precautions:
- Consult Loading Manuals: Never deviate from published loading data specific to your chosen powder, cartridge, and bullet. Using incorrect data can lead to dangerous pressure levels and potential catastrophic failure.
- Proper Equipment: Use only high-quality reloading equipment that is in good working order.
- Cleanliness: Maintain a clean workspace, free of debris and contaminants.
- Safety Glasses & Hearing Protection: Always wear appropriate safety glasses and hearing protection.
- Single-Stage Loading: Start with a single-stage press to learn the fundamentals before progressing to more advanced techniques.
Conclusion: Alliant 20/28 – A Versatile Choice
Alliant 20/28 powder offers reloaders a versatile option for both handgun and some rifle applications. Its medium burn rate and consistent performance contribute to its popularity. However, understanding its limitations and always adhering to safe reloading practices is paramount. Remember to consult updated loading manuals before beginning any reloading project. This ensures safe and accurate loads, maximizing the potential of this popular powder. Always prioritize safety and responsible reloading practices.
