Finding reliable and safe load data for H110 powder is crucial for responsible reloading. This comprehensive guide provides information on using H110, emphasizing safety and accuracy. Always consult your reloading manual and manufacturer's data before attempting any reloading.

Understanding H110 Powder
H110, also known as Winchester 296, is a relatively slow-burning, magnum pistol powder. It's known for its excellent accuracy and performance in large-bore magnum cartridges, particularly those with heavier bullets. Its characteristics make it less suitable for smaller pistol calibers or lighter bullet weights. Its slower burn rate requires a larger case capacity to function optimally.
Key Characteristics of H110:
- Slow-burning: This is a key feature, making it ideal for magnum cartridges but unsuitable for others.
- Magnum pistol cartridges: Its primary application is in cartridges like .44 Magnum, .454 Casull, and .480 Ruger.
- Heavy bullet weights: It performs best with heavier bullets where its burn rate is optimized.
- High pressure: H110 produces high pressures; therefore, precise measurement and adherence to load data are paramount.
Finding Reliable H110 Load Data
Safety is paramount. Never deviate from published load data unless you have extensive reloading experience and the proper equipment, such as a pressure gauge.
Where to find reputable load data:
- Your reloading manual: This is the most important source. Always start here. Look for load data specific to your chosen caliber, bullet weight, and primer type.
- Powder manufacturer's website: Winchester (the manufacturer of H110) provides data on their website, though it's often presented in a broader context of their other products.
- Reputable reloading handbooks: Several publishers offer comprehensive reloading guides with extensive load data.
- Online forums (with caution): While online forums can be helpful for discussions, never rely solely on user-submitted data. Always cross-reference with official sources.
Factors Affecting H110 Load Data
Several factors influence the appropriate H110 load for your specific application:
- Caliber: The cartridge's case capacity significantly impacts the correct powder charge.
- Bullet weight: Heavier bullets generally require slightly more powder than lighter bullets.
- Primer type: Different primers can slightly influence pressure, so using the recommended primer type is crucial.
- Case brand and condition: Case volume can vary slightly between manufacturers and with case condition. Using consistent cases is vital.
- Altitude: Higher altitudes can affect powder burn rates, potentially requiring minor adjustments to load data. Consult your manual for altitude adjustments.
Safety Precautions When Using H110
- Always wear safety glasses: This should be a non-negotiable part of your reloading process.
- Work in a well-ventilated area: Gunpowder produces fumes; proper ventilation is essential.
- Use a powder scale: Accurately measure your powder charges. Never estimate.
- Double-check your work: Verify your powder charge and bullet seating depth before loading each round.
- Never mix powders: Never mix different types of gunpowder.
- Proper case preparation: Inspect and prepare your brass meticulously to ensure consistent performance.
- Understand your equipment: Ensure your reloading equipment is in good working order and you are proficient in its use.
Conclusion
Reloading with H110 can be rewarding, providing highly accurate ammunition. However, it's crucial to prioritize safety and precision. Always consult multiple reputable sources of load data before reloading and meticulously follow all safety precautions. Remember that this information is for educational purposes only and does not replace the necessity of consulting official manuals and data. Safe and accurate reloading practices are essential for your safety and the safety of others.
