Herco powder, a popular choice among reloaders, offers excellent performance across various calibers and applications. However, safe and effective reloading with Herco, or any powder, necessitates precise adherence to proven load data. This guide delves into the intricacies of Herco powder load data, emphasizing safety, accuracy, and best practices for responsible reloading.
Understanding Herco Powder
Herco is a relatively fast-burning, extruded powder known for its versatility. Its characteristics make it suitable for handgun cartridges and some rifle rounds, particularly those with shorter barrels. However, its burn rate necessitates careful attention to detail during the reloading process. Improper load data can lead to dangerously high pressures, potentially resulting in firearm damage or injury.
Key Properties of Herco Powder:
- Burn Rate: Relatively fast
- Applications: Primarily handguns, some rifle cartridges
- Versatility: Suitable for a range of bullet weights and calibers (but always consult load data specific to your chosen cartridge and bullet)
- Availability: Widely available from reputable reloading supply companies.
Finding Reliable Herco Load Data
Locating accurate and up-to-date load data is paramount for safe reloading. Never attempt to use data from unreliable sources or extrapolate data from different powders or calibers. The consequences can be catastrophic.
Reputable Sources of Herco Load Data:
- Powder Manufacturer's Data: The most reliable source is the official load data published by the powder manufacturer themselves (Herco's parent company). This data undergoes rigorous testing and ensures safety and performance within specific parameters. Always prioritize this information.
- Reputable Reloading Manuals: Established reloading manuals from companies like Lyman, Hornady, Sierra, and others, provide extensively tested load data from various powder manufacturers. These manuals are valuable resources for experienced and novice reloaders alike.
- Online Forums (Use Caution): While online forums can offer anecdotal information and experiences, they should never replace official manufacturer data or established reloading manuals. Treat any information found online with extreme caution and always verify with a trusted source before use.
Safe Reloading Practices with Herco Powder:
Beyond simply finding the right load data, consistent and meticulous reloading practices are crucial for safety:
- Cleanliness: Maintain a clean and organized reloading workspace. Powder contamination can significantly impact performance and safety.
- Consistent Measurement: Employ a reliable powder measure and double-check every charge. Inconsistencies in powder charges are a major source of pressure variations.
- Proper Case Preparation: Ensure cases are properly sized, cleaned, and primed. Improper case preparation can lead to pressure spikes.
- Careful Seating Depth: Use a bullet seating die to consistently set bullet depth. This is critical for consistent chamber pressures.
- Start Low, Work Up (Slowly): Always start with the minimum charge weight listed in the load data. Work up gradually, meticulously documenting each step. Chronograph readings can assist in gauging pressure, but visual inspection for signs of excessive pressure is also crucial.
- Never exceed Maximum Loads: Exceeding maximum load data is extremely dangerous and should never be attempted.
- Regular Inspection: Regularly inspect your firearm for signs of excessive pressure, such as flattened primers, excessively bulged cases, or unusual sounds during firing.
Interpreting Herco Load Data Charts:
Load data charts typically list the following information:
- Caliber: The specific cartridge for which the data applies.
- Bullet Weight: The weight of the projectile used.
- Powder Charge (grains): The weight of Herco powder to use.
- Primer Type: The type of primer recommended.
- COL (Cartridge Overall Length): The overall length of the loaded cartridge.
- Velocity (fps): The expected muzzle velocity.
- Pressure (psi): The expected chamber pressure. This is often omitted for handguns but critical for rifles.
