Trail Boss is a unique, very-low-volume powder designed for handgun reloading, especially popular for light loads in revolvers and larger handgun calibers. Understanding its properties and utilizing accurate Trail Boss reloading data is crucial for safe and effective shooting. This guide will provide a comprehensive overview, including safety considerations and data tables. Remember to always consult your reloading manual and follow its instructions before attempting any reloading. This information is for educational purposes only.
Understanding Trail Boss Powder
Trail Boss differs significantly from other handgun powders. Its primary characteristic is its exceptionally low density. This allows for a large volume of powder to be used, even for light loads, filling a significant portion of the case. This volume-based approach reduces the risk of accidental double-charges, a common cause of firearm damage.
Key Features of Trail Boss:
- Low Density: Allows for a large volume of powder, mitigating the risk of double charges.
- Volume-Based Charging: Instead of weighing charges, many reloaders use a powder measure to fill the case to a certain level.
- Designed for Light Loads: Typically used for low recoil target practice or reduced-recoil loads for specific applications (like Cowboy Action Shooting).
- Generally Clean Burning: Produces relatively less fouling compared to some other powders.
- Not Suitable for All Calibers/Applications: Its low density limits its use in high-pressure loads or higher-power cartridges.
Important Note: Never substitute Trail Boss for other powders. Its unique properties require adherence to specific loading data. Using incorrect data can result in dangerous pressure levels.
Why Use Trail Boss?
Trail Boss offers several advantages for handgun reloaders, especially beginners:
- Increased Safety: The large volume of powder used significantly reduces the risk of accidental double charges, a leading cause of firearm damage.
- Ease of Use: The volume-based charging method simplifies the reloading process, making it more accessible to beginners.
- Reduced Recoil: Light loads are ideal for practice, especially for shooters with less upper body strength or those new to firearms.
- Good Accuracy: Despite being a light load powder, Trail Boss often provides acceptable accuracy levels for target shooting.
- Suitable for Large Calibers: Trail Boss is well-suited for larger handgun calibers that often require heavier bullet weights.
Trail Boss Reloading Data: A Word of Caution
Disclaimer: The data presented below is for informational purposes only and should not be considered a substitute for reloading manuals or data from reputable sources like Alliant Powder's website. Always cross-reference with your reloading manual and use the data specific to your components (bullets, primers, cases). Improper reloading can lead to serious injury or death.
Sample Trail Boss Reloading Data (Illustrative Only – DO NOT USE WITHOUT VERIFYING WITH YOUR MANUAL)
The following table provides example data. Always verify with your specific manual and components. Note: These are examples and may not be suitable for your specific firearm.
| Caliber | Bullet Weight (grains) | Case | Primer | Trail Boss (volume – not weight) | COL (inches) | Notes |
|---|---|---|---|---|---|---|
| .38 Special | 158 gr LSWC | New | Small Pistol | ~ 1/4 case | 1.57 | For example - check manual! |
| .357 Magnum | 125 gr JHP | New | Small Pistol | ~ 1/3 case | 1.57 | Start low and work up. |
| .44 Special | 240 gr SWC | New | Large Pistol | ~ 1/2 case | 1.57 | For example - check manual! |
| .45 Colt | 250 gr RNFP | New | Large Pistol | ~ 1/3 to 1/2 case | 1.57 | Loads will vary widely depending on case capacity, your firearm, and bullet weight. |
Understanding the Table:
- Caliber: The specific firearm cartridge.
- Bullet Weight: The weight of the projectile in grains.
- Case: New brass is preferred for consistent results.
- Primer: Type of primer to be used.
- Trail Boss: The approximate volume of Trail Boss to use. This is a volume measurement, not a weight measurement. This is where using a powder measure designed for Trail Boss is critical.
- COL: Cartridge Overall Length – the total length of the loaded cartridge. Measure this carefully.
- Notes: Additional information on precautions and recommendations.
Step-by-Step Reloading with Trail Boss (General Outline – Always consult your manual)
- Gather Supplies: Assemble all necessary reloading equipment: a reloading press, dies, powder measure (specifically designed for volume measurement, if possible), cases, bullets, primers, scale, and safety glasses.
- Prepare Cases: Resize, clean, and deprime your brass cases.
- Charge Cases: Use a powder measure to dispense the appropriate volume of Trail Boss into each case. Do not weigh charges with Trail Boss; it's a volume-based powder.
- Seat Primers: Carefully seat a primer in each case.
- Seat Bullets: Use the bullet seating die to seat the bullets to the correct overall length (COL) specified in your reloading data.
- Inspect Rounds: Carefully inspect each loaded round for any defects or inconsistencies.
- Test Fire: Start with a small number of rounds and carefully check for function and accuracy. Gradually increase the number of rounds as confidence builds. Always start with minimum loads and work up.
Conclusion: Safe and Responsible Reloading
Trail Boss offers a unique and safe approach to reloading for light handgun loads. However, the key to success is careful attention to detail, use of appropriate reloading data, and safe reloading practices. Always prioritize safety and consult your manual before commencing any reloading activity. Remember to double-check all measurements and to regularly clean and maintain your equipment. Enjoy the rewarding experience of reloading, but never compromise safety.
