Introduction
Benefits of Reloading
Reloading ammunition is more than just a hobby; it’s a craft. It offers firearm enthusiasts a unique opportunity to tailor their ammunition to their specific needs, maximizing performance and accuracy. Beyond the customization aspect, reloading can lead to significant cost savings over time, especially for those who shoot frequently. The ability to experiment with different bullet weights, powder types, and primers opens up a world of possibilities for precision shooting and hunting. But the path to successful reloading starts with knowledge and respect for the craft.
Safety First
At the heart of safe and effective reloading lies a commitment to using reliable load data and adhering to strict safety protocols. This means carefully consulting reputable sources, understanding the properties of each component, and meticulously following established procedures. Neglecting these principles can lead to dangerous outcomes, including firearm damage or, even worse, personal injury.
Introducing Accurate 4064
This article delves into a widely-respected propellant for reloading, Accurate 4064 powder. Renowned for its versatility, Accurate 4064 offers excellent performance across a range of calibers, making it a favorite among reloaders seeking accuracy and consistency.
Article Purpose
The aim of this guide is to provide reloaders with detailed and accessible load data specifically for Accurate 4064 powder.

Understanding Accurate 4064 Powder
Powder Characteristics
Accurate 4064 powder is a double-base, extruded propellant known for its excellent consistency and accuracy potential. Its grain shape is that of a stick, which meters well through most powder measures. This powder is typically used for heavier bullet weights in several cartridges. Its burn rate is considered to be in the medium-slow range, which makes it suitable for a wide array of rifle cartridges. This gives reloaders the versatility to choose from a diverse range of bullet weights for their specific shooting requirements.
Performance and Accuracy
Many shooters and hunters look to this powder because it is known for being able to produce tight groups at varying distances. Its ability to efficiently utilize the energy from the cartridge can result in minimal velocity variations, leading to more predictable bullet trajectories and reduced wind drift.
Recommended Calibers
While Accurate 4064 is versatile, it really shines in specific cartridges.
It is particularly well-suited for cartridges such as:
- .308 Winchester
- .22-250 Remington
- 6.5 Creedmoor
- .30-06 Springfield
Advantages and Disadvantages
The advantages of using Accurate 4064 include its consistent performance across a range of temperatures, making it reliable in various shooting environments. Also, it provides accuracy, a benefit desired by all shooters.
However, it also has some possible disadvantages. It may not be the optimal choice for very light bullets in some cartridges. Also, the specific loading information available for certain cartridges may be limited.
Load Data Sources
When gathering load data, always consult reputable sources such as the manufacturer’s website, well-established reloading manuals (such as those produced by Speer, Hodgdon, or Sierra), and other trusted sources. These sources provide load data that has been carefully tested and proven safe.
Safety First: Reloading Precautions
Safety is paramount when it comes to reloading ammunition. It is critical to adhere to a set of safety precautions to protect yourself and others from harm and to prevent damage to your firearms.
Eye Protection
Always wear safety glasses. Reloading can involve the potential for stray particles, sparks, and even the accidental ejection of components, making eye protection an absolute necessity.
Gloves
Use gloves. Reloading operations involve handling chemicals and components that may be irritating or harmful if they come into contact with your skin. Gloves provide a protective barrier.
Storage
Proper storage is essential. Keep powder in its original container, away from direct sunlight, heat, and moisture. Store powder in a cool, dry place. Be sure that powder and primers are kept separate from each other, and never store them with flammables.
Case Inspection
Inspect cases before reloading. Check for cracks, dents, or other signs of damage. Properly prepare cases by trimming them to the correct length, chamfering, and deburring the case mouth.
Precise Measurements
Accuracy in all measurements is required. Use a calibrated powder scale and appropriate measuring tools to ensure precise and repeatable powder charges. Slight variations can dramatically impact performance and safety.
Overpressure Indicators
Learn to recognize the signs of overpressure. These indicators can include flattened primers, difficult bolt extraction, and case head expansion. If you observe any of these signs, immediately cease reloading and evaluate your load data and equipment.
Start Low, Work Up
Always begin with the minimum recommended powder charge and gradually increase the charge weight. This allows you to safely determine the optimal load for your firearm. Never exceed the maximum recommended charge listed in your reloading manual or from the powder manufacturer.
Avoid Cross-Contamination
Keep your powder and other reloading components separate and organized to prevent accidental mixing. A mistake in powder choice can have devastating results.
Safe Environment
Work in a well-ventilated area, away from flammable materials. Avoid distractions and focus on the task at hand.
Documentation
Meticulously document every aspect of your reloading process. Record the powder used, bullet weight, primer type, and powder charge for each load. This information is crucial for reproducing your loads and troubleshooting any problems.

Factors Affecting Accuracy and Performance
Achieving the best accuracy and performance requires attention to detail throughout the reloading process. Several factors can significantly impact your results.
Bullet Selection
Choosing the correct bullet weight and type for your rifle’s barrel twist rate is critical. A bullet that’s too heavy or too light for your twist rate may not stabilize properly, leading to poor accuracy. Consider the intended use; bullets made for hunting will have a different design from bullets for long-range target shooting.
Seating Depth
Seating depth refers to the distance the bullet is seated inside the case. It can affect both accuracy and pressure. Adjusting the seating depth by small increments, especially in conjunction with powder charge adjustments, can fine-tune groups.
Primer Selection
Different primers can have slightly different burn rates and ignition characteristics. Experimenting with different primer types can sometimes improve accuracy. The primer type should also be appropriate for the powder charge and the cartridge.
Environmental Conditions
Temperature and altitude can affect ballistics. Hotter temperatures can increase pressure, while higher altitudes can affect bullet trajectory. Be aware of these factors and adjust your loads accordingly, especially for long-range shooting.
Consistent Reloading
The most critical factor for achieving consistent performance is consistent reloading practices. Always use the same procedures, the same tools, and pay attention to every detail. Any inconsistency in the reloading process can negatively affect the outcome.
Tips for Troubleshooting
Even with meticulous attention to detail, problems can occur. Recognizing the signs of trouble is an important skill.
Excessive Pressure
Signs of excessive pressure include flattened primers, difficult bolt lift, and case head expansion. If any of these are present, stop reloading immediately and investigate the cause. It could be a problem with your powder charge, case preparation, or a combination of factors.
Accuracy Issues
If you’re experiencing grouping problems, make adjustments, while following safety protocol, to the powder charge and seating depth. Sometimes, a different primer might help improve the accuracy.
Adjusting Powder Charges
Minor adjustments to the powder charge can help optimize performance. However, always work within safe limits. If your load is consistently under-performing, try slightly increasing the powder charge. If the groups are opening up or if pressure signs begin to appear, reduce the charge.
Consulting Experts
If you’re struggling with reloading issues, don’t hesitate to consult a qualified reloading expert. They can often provide valuable insight and help you diagnose problems.
