Hodgdon HP-38 is a popular powder choice for handgun reloaders, known for its versatility and consistent performance. However, it's crucial to understand that this information is for educational purposes only and should not be considered a substitute for official loading manuals. Always consult the latest edition of the Hodgdon reloading manual and other reputable sources before attempting any reloading. Improper reloading practices can lead to serious injury or death.
Understanding Hodgdon HP-38
HP-38 is a spherical propellant, meaning its grains are round. This contributes to its relatively consistent burning rate and reduced pressure spikes compared to extruded powders. This makes it a good choice for a variety of cartridges, but especially those where consistent pressure is paramount. It's frequently used in .38 Special, .357 Magnum, and other handgun cartridges. Its relatively low-to-medium burn rate makes it suitable for both light and heavier bullet weights.
Key Considerations Before Reloading with HP-38
Before you even think about starting, remember these vital points:
- Safety First: Reloading is inherently dangerous. Careless practices can lead to catastrophic consequences. Always wear appropriate safety glasses and hearing protection.
- Proper Equipment: Invest in high-quality reloading equipment that's in good working order. A faulty press or inaccurate scale can lead to dangerous overloads.
- Accurate Measurement: Precise powder measurement is critical. Use a reliable powder scale and double-check your measurements. Even slight variations can significantly impact pressure.
- Start Low, Work Up: Begin with the minimum charge listed in the Hodgdon manual and work your way up gradually, carefully monitoring pressure signs. Never exceed the maximum listed charge.
- Case Preparation: Thoroughly clean, inspect, and resize your brass before loading. Debris or damaged cases can negatively impact performance and safety.
- Bullet Selection: Ensure your bullets are properly sized and lubricated for your chosen cartridge.
Finding Reliable HP-38 Load Data
The most reliable source of load data is the official Hodgdon Reloading Manual. This manual provides detailed information on safe and effective loads for a wide range of cartridges and bullet weights using HP-38 powder. You can typically find this manual online through their official website, or at most sporting goods stores that carry reloading supplies.
Beyond Hodgdon's manual, you might also consult other reputable sources, such as:
- Alliant Powder Manuals: Alliant is another major powder manufacturer with potentially overlapping data.
- AccurateShooter.com: This online resource frequently features reloading articles and information.
- Local Reloading Clubs: Connecting with experienced reloaders can offer valuable tips and advice.
Remember: Never mix and match data from different sources. Always stick to the manufacturer's recommended load data for your specific components.
Understanding Load Data Charts
Load data charts typically list the following information:
- Cartridge: The specific cartridge being loaded (e.g., .38 Special).
- Bullet Weight: The weight of the bullet in grains (e.g., 158 gr).
- Powder Charge: The weight of HP-38 powder in grains. This is the most critical piece of information.
- Primer: The type of primer to use (e.g., CCI Small Pistol).
- COL (Case Overall Length): The maximum overall length of the loaded cartridge.
- Pressure: The pressure generated by the load in PSI (pounds per square inch). This should be carefully monitored.
Safety Precautions: A Final Reminder
Reloading is a rewarding hobby, but safety should always be your top priority. Always follow these guidelines:
- Never exceed maximum load data.
- Double-check your measurements.
- Inspect your loaded ammunition carefully.
- Store your ammunition properly.
- Never handle loaded ammunition carelessly.
