Finding accurate load data for IMR 4064 powder is crucial for safe and effective reloading. This isn't something to take lightly; improper loads can lead to serious injury or damage to your firearm. This guide will help you understand where to find reliable data and what factors influence your specific load. Always prioritize safety and double-check your work.
Understanding the Importance of Accurate Load Data
IMR 4064 is a popular, versatile powder known for its suitability in a wide range of cartridges. However, its versatility also means that load data varies significantly depending on the cartridge, bullet weight, and other factors. Using inaccurate data can result in:
- Squib loads: A squib load is a cartridge where the powder charge is insufficient to fully propel the bullet. This can lead to a dangerous obstruction in the barrel.
- Overpressure: An excessive powder charge can cause dangerously high pressure within the firearm, potentially damaging the firearm or causing injury.
- Inconsistent accuracy: Incorrect loads often lead to poor accuracy and inconsistent performance.
Where to Find Reliable 4064 Load Data
Never rely on internet forums or unverified sources for load data. Always consult reputable sources that provide meticulously tested and verified information. These include:
- The Powder Manufacturer's Website (Hodgdon): Hodgdon, the manufacturer of IMR 4064, is the most trustworthy source for load data. Their website provides extensive data covering a range of cartridges and bullet weights. This should be your primary source.
- Reloading Manuals: Major reloading manual publishers like Lyman, Hornady, and Sierra meticulously test and compile load data. These manuals are excellent resources and offer detailed explanations.
- Independent Reloading Publications: Some reputable firearms magazines and publications also publish thoroughly tested load data. Always verify the source's credibility.
Factors Influencing Your 4064 Load
Several factors determine the appropriate powder charge for your specific reloading needs:
- Cartridge: The cartridge's case capacity directly impacts the maximum safe powder charge. A larger capacity case allows for a larger charge, while a smaller case requires a smaller charge.
- Bullet Weight: Heavier bullets generally require more powder to achieve optimal velocity.
- Bullet Type: Different bullet designs (e.g., jacketed, lead, hollow point) can influence pressure and accuracy.
- Primer Type: While less impactful than other factors, primer type can slightly affect pressure.
- Rifle/Handgun: The firearm itself plays a role. Always use load data specific to the type of firearm you are using.
Steps to Safe Reloading with IMR 4064
- Consult multiple reliable sources: Don't rely on a single source. Compare data from several reputable manuals and the manufacturer's website.
- Start low and work up: Begin with the minimum charge listed in your chosen data source. Gradually increase the charge in small increments (0.1-0.2 grains), carefully documenting each load.
- Chronograph your loads: A chronograph measures the velocity of your rounds, helping you fine-tune your loads for accuracy and optimal performance.
- Always inspect your cases: Check for any signs of overpressure after firing, such as flattened primers, excessive case expansion, or unusual signs of wear.
- Never exceed maximum load data: Always stay within the recommended maximum load listed in your source. Exceeding this limit is extremely dangerous.
