Essential Safety Practices
Safety Equipment and Procedures
Before embarking on any reloading venture, safety must be the paramount concern. Reloading involves handling potentially dangerous materials and processes, so strict adherence to safe practices is non-negotiable. Always, without exception, wear appropriate safety glasses to protect your eyes from debris and potential explosions. Gloves are also recommended to protect your hands from chemicals and potential burns. Work in a well-ventilated area to minimize exposure to fumes and particulate matter.
Importance of Data Adherence
The cornerstone of safe reloading is meticulous adherence to established data. Always consult reputable reloading manuals published by bullet, powder, and brass manufacturers. These manuals provide detailed guidelines for safe loads based on extensive testing. Never deviate from these published data unless you are an experienced reloader and have the knowledge to analyze the effects of modifications. Starting with the minimum recommended powder charge and gradually increasing it while carefully monitoring for pressure signs is critical. Never exceed the maximum recommended loads.
The Value of a Chronograph
A chronograph is an invaluable tool for reloading. This device measures the velocity of your reloaded ammunition, allowing you to verify that your loads are performing as expected and to detect any anomalies. Observe your brass cases carefully after each shot. Signs of excessive pressure, such as flattened primers, cratered primer pockets, hard bolt lift, or ejector marks on the case head, are serious warnings that indicate the load is too hot and should be immediately reduced.
Safe Storage Practices
Proper storage of reloading components and loaded ammunition is equally important. Store powders, primers, and loaded ammunition in a cool, dry place away from direct sunlight and potential sources of ignition. Never store ammunition in a hot car or any location where temperatures may fluctuate significantly. Segregate components and loaded ammunition by type to prevent accidental mixing.
Assembling the Pieces
Brass Selection and Preparation
The quality of the components you select directly impacts the performance of your reloaded ammunition. A thoughtful approach to component selection is the foundation of superior handloads. Brass selection plays a critical role. While the .260 Remington is a relatively easy cartridge to reload, using high-quality brass will enhance accuracy and case life. Look for brass from reputable manufacturers known for consistency, like Lapua, Norma, or Peterson. Carefully prepare your brass before reloading. This includes cleaning the brass, trimming the case length to the recommended specification, deburring the case mouth, and chamfering the primer pocket. Proper brass preparation ensures consistent bullet seating and chambering. Regular trimming prevents changes in the overall length over multiple reloading cycles.
Primer Choices
The primer ignites the powder charge, initiating the firing sequence. Select a primer specifically designed for use in the .260 Remington. Small rifle primers are typically used. Ensure the primer is seated flush or slightly below the case head for optimal ignition and to prevent interference with the bolt face. Familiar brands include Federal, CCI, and Remington. Choose the primer which performs best in your rifle, and is best suited to the chosen powder.
Powder Considerations
Choosing the right powder is a pivotal decision in reloading the .260 Remington. The powder type you select will influence factors like velocity, pressure, and accuracy. For the .260 Remington, a range of powders work well. Look for powders with burn rates suitable for medium-capacity cartridges and a good balance of speed and stability. Consider powder density, which is the weight of the powder in a given volume. Denser powders often meter more consistently. Some popular choices include powders in the medium-burn-rate range like Hodgdon H4350, IMR 4451, and Reloder 17. Experiment to find the powder that provides the best combination of accuracy, velocity, and consistency in your particular rifle.
Bullet Selection
The bullet is the projectile that travels downrange and impacts your target. The .260 Remington is known for its versatility and can handle a wide range of bullet weights. The bullet weight you select will depend on your intended use. Heavier bullets generally offer better ballistic coefficients and downrange performance, making them suitable for long-range shooting and hunting. Lighter bullets may offer flatter trajectories at shorter ranges, with less wind drift. Popular choices include those from Sierra, Hornady, Berger, and Nosler. Consider the twist rate of your rifle’s barrel when selecting bullets. A faster twist rate (e.g., 1:8”) is generally required to stabilize heavier bullets effectively. Match your twist rate to the bullet weight for optimal results.

Step-by-Step Reloading Process
The reloading process is a methodical sequence of steps that require careful attention and precision. A systematic approach is key to producing safe and consistent ammunition. First, clean your brass thoroughly. Use a case cleaner and tumble the brass. Follow the specific recommendations for the cleaning method. Once cleaned, remove the spent primers from the case and resize the case to restore its dimensions. This process also de-primes the case. After resizing, you will need to prime your case. Insert a new primer into the primer pocket using a priming tool. Next, charge the case with the appropriate powder using a powder measure or a scale. Weigh each charge if required. Carefully seat the bullet into the case to the specified overall cartridge length (COAL). Finally, inspect the loaded rounds for any defects or inconsistencies before using them.
Equipment Considerations
The equipment you use for reloading can affect the quality of the final product. Ensure the right tools.
Troubleshooting Concerns
Common Reloading Issues
Reloading, while rewarding, is not without its challenges. Understanding potential problems and how to address them is critical for ensuring safety and achieving desired results. Failure to feed or extract can be caused by a variety of issues, including improper case sizing, incorrect COAL, or damaged brass. Problems with feeding can also be caused by faulty magazines. Carefully inspect each loaded round before chambering. If you experience extraction issues, check to see that the brass is properly sized and crimped.
Velocity and Pressure Issues
Inconsistent velocity is often a sign of inconsistent powder charges, poor bullet seating, or varying brass quality. Ensure your powder charges are consistent. Pay close attention to each step to identify any variables. Pressure signs can indicate potential problems. If you observe pressure signs such as flattened primers, cratered primer pockets, hard bolt lift, or ejector marks on the case head, stop shooting immediately. These signs are a warning and indicate the load is too hot. Reduce the powder charge significantly and consult a reloading manual or expert.
Maximizing Precision
Accuracy Testing Procedures
Accuracy testing is a crucial part of the reloading process. Accuracy tests will allow you to find the best loads. Use a stable shooting platform such as a benchrest or shooting vise. Focus on consistently good shooting habits. The first step is to find the best groups. Shoot three- or five-shot groups at a known distance. Start with the starting load, and then increase the powder charge gradually. Observe the group size as you increase the charge. Adjust your load as necessary. If you see signs of pressure, reduce the load.
Documenting and Refining Loads
Once you find the most accurate load, document all of your measurements and results. Record the bullet weight, powder charge, primer type, and overall cartridge length. This will allow you to reproduce the load in the future. Keep a detailed log of your reloading process.
Conclusion
The .260 Remington is a highly accurate cartridge that offers excellent performance in a variety of applications. With careful attention to detail and using the right tools, you can handload ammunition that will achieve its full potential. By mastering the art of handloading, you can tailor your ammunition to your rifle’s unique characteristics and your specific shooting needs. Remember, the key to success is a commitment to safety, a willingness to experiment, and an understanding of the fundamental principles of ballistics. Always refer to the latest reloading manuals for specific data. This will ensure safety and maximum results.
