The 6.5 Creedmoor cartridge has rapidly gained popularity among long-range shooters and hunters, renowned for its accuracy, mild recoil, and excellent ballistic coefficient. H4350 powder is a favorite among reloaders for this caliber, offering impressive performance and consistent results. However, it's crucial to remember that reloading ammunition can be dangerous if not performed correctly. Always consult your reloading manual and prioritize safety. This guide provides general information and should not be considered a substitute for safe reloading practices.
Understanding H4350 and its Suitability for 6.5 Creedmoor
Hodgdon H4350 is a relatively slow-burning, extruded powder known for its excellent metering characteristics and suitability for a wide range of cartridges. Its burn rate makes it an ideal choice for the 6.5 Creedmoor, providing consistent accuracy and velocity across different bullet weights. Its performance shines particularly well with heavier bullets, commonly used in long-range shooting.
Key Considerations Before Reloading
Before diving into specific load data, let's address some crucial aspects:
- Safety First: Always wear safety glasses and hearing protection. Ensure adequate ventilation. Never exceed the maximum recommended charge weight specified in your reloading manual.
- Your Reloading Manual: This guide offers general information. Always refer to your specific reloading manual for the most accurate and safe load data for your chosen components. The data below serves as a starting point only.
- Components: The performance of your loads will vary depending on your chosen primers, bullets, and brass. Consistency in these components is key for achieving repeatable accuracy.
- Scale Accuracy: Using a precise reloading scale is paramount. Even minor inconsistencies in powder charge can significantly impact accuracy and safety.
- Progressive vs. Single-Stage Press: The type of press you use will influence your reloading workflow but won't affect the safety or accuracy of the final product.
Sample 6.5 Creedmoor Load Data with H4350 (Starting Loads Only)
Disclaimer: The following load data is for informational purposes only. It is a general guideline and should not be considered definitive. Always confirm load data with your specific reloading manual and components before reloading.
| Bullet Weight (grains) | Bullet Type | Powder (H4350, grains) | Primer | COL (inches) | Notes |
|---|---|---|---|---|---|
| 140 | Match Grade | 42.0 | Fed 210M | 2.800 | Starting Load - Work up gradually |
| 140 | Hunting | 43.0 | Win LR Primer | 2.800 | Starting Load - Work up gradually |
| 143 | Match Grade | 41.5 | CCI 200 | 2.800 | Starting Load - Work up gradually |
| 147 | Match Grade | 40.5 | Fed 210M | 2.800 | Starting Load - Work up gradually |
COL refers to Cartridge Overall Length. This measurement should be verified using your specific bullet and case components. Slight variations are normal.
Working Up Loads Safely
Working up to a safe and accurate load is a crucial step. Never jump to maximum loads. This is a gradual process involving:
- Starting Low: Begin with the minimum powder charge listed in your manual or a reputable source.
- Incremental Increases: Gradually increase the powder charge in small increments (0.3 grains at a time).
- Careful Observation: Pay close attention to pressure signs during firing. Excessive pressure signs include flattened primers, overly hard bolt lift, or unusual sounds.
- Accuracy Testing: After each increment, test the accuracy of your loads at the range.
- Note-Taking: Maintain meticulous records of your load data, including bullet weight, powder charge, primer type, and accuracy results.
Factors Influencing Load Performance
Several factors beyond the core components can affect your results:
- Case Capacity: Variations in brass capacity can subtly influence performance. Consistent case preparation is important.
- Environmental Conditions: Temperature and humidity can affect powder burn rate.
- Rifle Characteristics: Your specific rifle’s barrel characteristics and headspace can play a role in final accuracy and performance.
Conclusion
Reloading 6.5 Creedmoor ammunition with H4350 can be rewarding for those seeking precision and control over their ammunition. However, it necessitates meticulous attention to detail, safety precautions, and a thorough understanding of reloading practices. Always refer to your reloading manual and prioritize safety above all else. Remember, this information is intended as a general guide. Consult your reloading manual before attempting to reload any ammunition.
