This guide provides comprehensive information on loading data for the .223 Remington cartridge using Hodgdon H335 powder. Safety is paramount when reloading ammunition; always consult your reloading manual and follow its instructions precisely. This information is for educational purposes only and should not be considered a substitute for professional guidance. Always double-check your measurements and procedures before loading.
Understanding the Components
Before diving into load data, let's review the key components involved in reloading .223 Remington ammunition:
- Case: The .223 Remington case is a bottlenecked cartridge case, typically made of brass. Proper case preparation (cleaning, resizing, and priming) is crucial for consistent and safe performance.
- Primer: Small rifle primers are used in .223 Remington reloading. The primer ignites the powder, initiating the combustion process. Using the incorrect primer type can lead to dangerous situations.
- Powder: Hodgdon H335 is a popular extruded powder known for its consistent burning rate and suitability for a range of .223 Remington loads. Accurate powder measurement is critical for safe and consistent results. Never substitute powders without consulting loading manuals.
- Bullet: Bullet weight and type significantly influence the ballistics of your load. Popular choices include various weights and designs, from full metal jacket (FMJ) to hollow point (HP) and match-grade bullets.
Hodgdon H335 Load Data for .223 Remington
The following table presents sample load data for .223 Remington using Hodgdon H335 powder. This is not an exhaustive list and should only be considered a starting point. Always refer to the most current Hodgdon reloading manual for the most up-to-date and comprehensive data. Remember to always start at the minimum charge weight and work your way up slowly, carefully monitoring pressure signs. Never exceed the maximum charge weight.
| Bullet Weight (grains) | Bullet Type | Powder Charge (grains) | COL (inches) | Primer | Notes |
|---|---|---|---|---|---|
| 55 | FMJ | 24.0 - 25.0 | 2.260 | Small Rifle | Start low, work up |
| 62 | FMJ | 23.0 - 24.0 | 2.260 | Small Rifle | Start low, work up |
| 77 | SMK | 21.5 - 22.5 | 2.260 | Small Rifle | Match grade bullet, start low |
COL refers to Cartridge Overall Length. This is the total length of the loaded cartridge. Maintaining consistent COL is vital for accurate and safe performance.
Understanding the Table
Each row in the table represents a potential load. The bullet weight, type, powder charge, and COL are all critical factors. The "Notes" column provides additional guidance, emphasizing the importance of starting with the minimum charge weight and working up gradually.
Safety Precautions: Absolutely Essential!
- Always wear safety glasses and hearing protection while reloading.
- Never exceed the maximum listed charge weight. Overloading can cause catastrophic equipment failure and serious injury.
- Use a reliable powder scale to ensure accurate powder measurements.
- Inspect your cases and bullets for defects before loading.
- Store your ammunition in a cool, dry place away from children and pets.
- Regularly clean your reloading equipment to maintain accuracy and safety.
- Consult your reloading manual for detailed instructions and safety precautions.
- Understand the signs of excessive pressure: These include flattened primers, excessive case expansion, and unusual sounds or recoil. If you observe any of these signs, immediately stop loading and investigate the cause.
Factors Affecting Load Data
Several factors can influence the optimal load data for your specific setup:
- Bullet Type: Different bullet designs (FMJ, HP, etc.) have varying ballistic coefficients and may require adjustments to the powder charge.
- Case Manufacturer: Variations in case capacity between manufacturers can affect pressure.
- Powder Lot: Even within the same powder type, variations in powder lots can exist.
- Environmental Conditions: Temperature and humidity can affect powder performance.
Always carefully monitor your loads for signs of excessive pressure and adjust your load data accordingly.
Troubleshooting and Further Resources
