The .223 Remington cartridge remains incredibly popular for a multitude of reasons: its versatility, accuracy, and affordability make it a favorite among target shooters, hunters, and those seeking self-defense options. H335 powder is a common and effective propellant often chosen for .223 Remington loads. This guide delves into the intricacies of H335 load data for the .223 Remington, emphasizing safety, accuracy, and responsible reloading practices.
Understanding the Importance of Accurate Load Data
Before we dive into specific H335 load data, it's crucial to understand the paramount importance of using reliable and accurate information. Improper load data can lead to dangerous pressure spikes, potentially causing damage to your firearm, injury, or even death. Never deviate from published data without a thorough understanding of reloading principles and extensive experience.
This information is for educational purposes only. Always consult multiple, reputable sources of load data before attempting to reload ammunition. The load data presented below is for illustrative purposes only and should not be considered a substitute for information from your chosen manual.
Key Factors Affecting H335 Load Data in .223 Remington
Several factors significantly influence the optimal H335 load for your .223 Remington:
-
Bullet Weight: Heavier bullets generally require more powder to achieve optimal velocity. The bullet's weight is a cornerstone of your load development.
-
Bullet Type: Full metal jacket (FMJ), jacketed hollow point (JHP), and soft point (SP) bullets all have different ballistic coefficients and may require slightly different powder charges.
-
Case Capacity: Variations in case capacity between different manufacturers can affect pressure. Consistent case preparation is crucial.
-
Primer Type: Different primers can influence ignition and pressure. Small variations in primer type can necessitate slight adjustments to powder charge.
-
Rifle Barrel Length: Barrel length significantly impacts velocity. A longer barrel generally yields higher velocities.
-
Environmental Conditions: Temperature and humidity can affect powder burn rate and pressure.
Sample H335 Load Data (Illustrative Only - NOT for use!)
The following data is purely illustrative and should never be used for reloading. It is crucial to consult your own reloading manual and adjust based on your specific components and equipment.

| Bullet Weight (grains) | Bullet Type | H335 Powder Charge (grains) | Primer Type | COL (inches) | Notes |
|---|---|---|---|---|---|
| 55 | FMJ | 24.0 | Small Rifle | 2.260 | This is NOT a real load. Do not use. |
| 62 | JHP | 25.0 | Small Rifle | 2.250 | This is NOT a real load. Do not use. |
| 77 | SP | 26.5 | Small Rifle | 2.240 | This is NOT a real load. Do not use. |
Responsible Reloading Practices
Safe and effective reloading demands attention to detail and adherence to best practices:
-
Start Low, Work Up: Always begin with the minimum charge listed in your chosen reloading manual and gradually increase in small increments, carefully observing for any signs of excessive pressure.
-
Accurate Measurements: Invest in a high-quality powder scale and meticulously measure each powder charge. Consistency is key to safety and accuracy.
-
Proper Case Preparation: Thoroughly clean, inspect, and size your brass to ensure consistent performance.
-
Use a Loading Manual: Consult multiple, reputable reloading manuals from trusted manufacturers. Never rely on online sources alone.
-
Regular Equipment Maintenance: Ensure your reloading equipment is functioning properly and calibrated correctly.
-
Safety First: Always wear appropriate safety glasses and hearing protection when reloading.
Conclusion: The Importance of Diligence
Reloading .223 Remington ammunition with H335 powder can be a rewarding experience, offering cost savings and the ability to tailor loads to your specific needs. However, it's crucial to approach this practice with respect and diligence. The information provided here is purely for educational purposes, and the responsibility for safe reloading rests entirely with the reloader. Always consult multiple, reputable sources of load data and follow established safety procedures.
