Accurate powder measurement is essential for consistent performance. Using a powder measure ensures you get the correct amount of powder every time. Weighing a sampling of powder charges is recommended to verify that your powder measure is set correctly.
Bullet Seating Depth
When seating bullets, it’s crucial to ensure that the correct seating depth is achieved. The overall cartridge length (OAL) is defined by the reloading data, and seating the bullet to the correct depth ensures that the round chambers in the rifle correctly. Too short, and the bullet may not stabilize properly. Too long, and the round may not chamber. Maintaining consistency in seating depth will contribute to accuracy.
Suppressor Considerations
Reloading for suppressed firearms involves additional considerations, especially when using subsonic loads. Choose a powder that burns completely and consistently to avoid residue buildup in the suppressor.
Troubleshooting and Common Problems
Overpressure Indicators
Reloading carries the risk of issues. One is overpressure, which can be the result of exceeding maximum powder charges, or using an incorrect powder type. Signs of overpressure include flattened primers, primers that are beginning to flow into the firing pin hole, difficult bolt extraction, and case head separation. If you observe any of these signs, immediately stop the reloading process and disassemble the rounds.
Feeding and Extraction Problems
Problems with feeding or extraction can also occur. These may be related to the overall cartridge length, the case dimensions, or insufficient crimping. Ensure that your case meets the dimensional specifications for the cartridge and is properly crimped.
Accuracy Issues and Solutions
Accuracy can also be compromised, which could be related to several factors. The most likely factors affecting accuracy include the powder and bullet type, the powder charge, the seating depth of the bullet, and the condition of your rifle and barrel. Experiment with different loads, paying attention to groupings on the target, to see what yields the best results.
