Understanding H335 Powder and the .223 Remington
Hodgdon H335 is a popular extruded powder known for its excellent metering characteristics and suitability for various rifle cartridges, including the .223 Remington. It's a medium-burning powder, making it ideal for producing moderate to high velocities with consistent accuracy. The .223 Remington, a widely used cartridge for both hunting and target shooting, benefits greatly from H335's properties.
Choosing the Right Components for Your H335 .223 Loads
Before diving into load data, selecting the correct components is crucial. Factors like bullet weight, type, and case manufacturer can all affect the final load's performance and safety.
-
Bullets: Bullet weight significantly influences the required powder charge. H335 works well with a wide range of bullet weights, from 50 to 77 grains. Common choices include:
- 55-grain FMJ (Full Metal Jacket) - Good for target practice and plinking.
- 62-grain FMJ - A popular choice for general purpose shooting.
- 77-grain SMK (Sierra MatchKing) - Designed for long-range accuracy.
-
Cases: Use new or once-fired cases that are properly cleaned and inspected for any damage. Consistent case dimensions are crucial for reliable reloading.
-
Primers: Small rifle primers are typically used with H335 in .223 Remington loads. Choose a reputable brand like CCI, Federal, or Winchester.
-
Powder: Use only Hodgdon H335 powder. Ensure it's properly stored in a cool, dry place, and avoid cross-contamination with other powders.

The table below illustrates sample load data. Remember that these are samples and may not be suitable for your specific components.
| Bullet Weight (grains) | Bullet Type | Powder Charge (grains) | Primer | COL (inches) | Notes |
|---|---|---|---|---|---|
| 55 | FMJ | 24.0 - 25.0 | Small Rifle | 2.260 | Start low, work up carefully |
| 62 | FMJ | 23.0 - 24.0 | Small Rifle | 2.260 | Start low, work up carefully |
| 77 | SMK | 21.0 - 22.0 | Small Rifle | 2.260 | Start low, work up carefully |
COL refers to Cartridge Overall Length. Precise COL is crucial for optimal accuracy and safe function.
Understanding the Importance of Working Up Loads
"Start low and work up" is a fundamental reloading principle. Begin with the minimum powder charge listed in your manual, fire a few rounds, and carefully inspect the cases for any signs of pressure. Gradually increase the charge in small increments (0.1 to 0.3 grains) while closely monitoring pressure signs. Pressure signs can include flattened primers, excessive case expansion, or unusually loud reports. If you observe any pressure signs, immediately stop and reduce the charge.
Safety Precautions: A Critical Reminder
- Always wear safety glasses and hearing protection when reloading and shooting.
- Never mix powders.
- Store powder in a cool, dry place.
- Never exceed maximum loads.
- Inspect cases and bullets before loading.
- Clean your equipment regularly.
- Consult your reloading manual for detailed instructions and safety precautions.
- Follow all local and state laws regarding ammunition.
Case Study: Achieving Optimal Accuracy with H335
A fellow reloader, using a 62-grain FMJ bullet with H335, found that a powder charge of 23.5 grains provided the best accuracy in his rifle. He meticulously documented his loading process, keeping accurate records of his charges and results. This demonstrates the importance of experimentation and careful record-keeping to optimize your loads for your specific firearm.
Conclusion: Safe and Accurate Reloading with H335
