American Select powder is a popular choice among reloaders for its versatility and consistent performance across various calibers and applications. This comprehensive guide delves into the intricacies of American Select load data, providing you with the information you need to safely and effectively utilize this powder in your reloading endeavors. Understanding American Select powder load data is crucial for achieving optimal accuracy and safety. We'll cover everything from finding reliable data sources to interpreting the information and understanding the implications of variations in load components.
Understanding American Select Powder Characteristics
American Select is a spherical powder, known for its consistent burn rate and metering characteristics. This makes it a favored choice for both beginners and experienced reloaders alike. Its spherical shape contributes to a smoother, more consistent burn, leading to reduced pressure spikes and improved accuracy. This makes it suitable for a range of cartridges, from pistol rounds to rifle rounds.
- Burn Rate: American Select's burn rate is generally considered moderate, making it suitable for a wide variety of applications. However, the specific burn rate can vary slightly depending on the lot number, so always refer to the manufacturer's data for your specific lot.
- Metering: The spherical shape of American Select contributes to excellent metering characteristics, especially when using a powder measure. Consistent powder charges are vital for accuracy and safety. However, proper maintenance of your powder measure is still essential.
- Temperature Sensitivity: Like most powders, American Select exhibits some degree of temperature sensitivity. Extreme temperature variations can affect its burn rate. Always strive for consistent loading conditions and consider temperature compensation when loading in extreme environments.
Choosing the Right Data Source
Finding reliable load data is paramount for safe and accurate reloading. Never rely on anecdotal information or unverified sources. Here are some trusted sources:
- Hodgdon Powder Company: Hodgdon, the manufacturer of American Select, provides comprehensive load data on their website. This is the most reliable source for up-to-date and accurate information.
- Alliant Powder: Alliant also offers load data which might include American Select data if it's compatible with their other powders.
- Reloading Manuals: Major reloading manual publishers, such as Lyman, Sierra, and Hornady, include load data for various powders, including American Select, in their publications. Always ensure your manual is up-to-date.
- Online Forums: While online forums can be useful for sharing experiences, never rely solely on forum data for loading. Always cross-reference information with a trusted source.
Caution: Always start at the minimum load listed in your chosen data source and work your way up gradually. Never exceed the maximum listed load. Failure to do so can result in dangerous pressure spikes, potentially leading to equipment damage or injury.
Deciphering American Select Load Data
Load data typically includes the following information:
| Data Point | Description |
|---|---|
| Caliber | Cartridge for which the load data applies (e.g., .308 Winchester) |
| Bullet Weight | Weight of the projectile in grains (e.g., 150 grains) |
| Bullet Type | Type of bullet (e.g., jacketed hollow point, full metal jacket) |
| Powder | Type of powder used (in this case, American Select) |
| Powder Charge | Amount of powder in grains (this is the crucial data point) |
| Primer | Type of primer to be used (e.g., CCI Large Rifle Magnum) |
| Case Length (Optional) | May be specified for certain cartridges. |
| Velocity | Expected muzzle velocity in feet per second (fps) |
| Pressure | Pressure in PSI (pounds per square inch) - crucial for safety |
| Notes/Warnings | Important notes provided by the manufacturer. Essential to read! |
Case Studies and Examples
Let's consider a hypothetical example using data from a reloading manual. Imagine you are loading .308 Winchester ammunition using a 150-grain bullet. The manual might show the following data:
Example Load Data:
- Caliber: .308 Winchester
- Bullet Weight: 150 grains
- Bullet Type: Full Metal Jacket (FMJ)
- Powder: American Select
- Powder Charge: 43.0 grains
- Primer: CCI Large Rifle Magnum
- Velocity: 2650 fps (approximate)
- Pressure: 55,000 PSI (approximate)
Important Note: This is a hypothetical example. Always consult a reliable reloading manual or the powder manufacturer's website for the actual load data relevant to your specific components and equipment. Never use this data as is.
Safety First: Best Practices for Reloading with American Select
- Start Low, Go Slow: Always begin with the minimum powder charge listed in your data source and work up gradually.
- Double-Check Your Work: Carefully verify each step of the reloading process. Accuracy is paramount.
- Use a Reliable Scale: A precise powder scale is vital for consistent and safe reloading.
- Inspect Your Cases and Components: Ensure all components are clean and free of damage.
- Understand Your Equipment: Familiarize yourself with the operation of all your reloading equipment.
- Follow Safety Guidelines: Always adhere to the safety instructions provided by your equipment and powder manufacturers.
- Never Mix and Match Data: Do not combine data from different sources without thorough verification.
American Select powder, with its consistent performance and versatile nature, is a solid choice for reloaders. However, safe and successful reloading hinges on diligent attention to detail, a deep understanding of load data, and adherence to best practices. Always prioritize safety and consult trusted resources before undertaking any reloading activity.
