How Often Should I Test Different Ammo for Accuracy?

Regular Ammunition Testing

Testing ammunition regularly is crucial for maintaining accuracy in your rifle. This is especially true if you use a bolt-action rifle, as the bolt head and chamber can become overly worn, affecting accuracy. Aim to test different ammo every 100-200 rounds, depending on the frequency of use. For instance, if you hunt frequently, you may need to test ammo every 100 rounds. However, if you only go hunting a few times a year, testing every 200 rounds might be sufficient.

Choosing the Right Ammunition for Testing

When selecting ammo for accuracy testing, look for high-quality, match-grade cartridges that are designed for your specific rifle. A good starting point is to choose ammo with a bullet weight that is within 10 grains of the original load you are using. For example, if you are using 150-grain bullets, test 140-grain or 160-grain bullets. This will help you identify any potential issues with the original load and give you a baseline for comparison.

Interpreting Test Results

When testing different ammo, pay attention to the group size and shape. A well-aimed, well-cued shot should land within 1-2 inches of the center of the target. If the group is larger than expected, consider adjusting your rifle’s zero, checking the ammunition for proper seating, or inspecting the rifle’s barrel for signs of wear. Keep a record of your test results to track any changes in your rifle’s performance over time, allowing you to make informed decisions about ammunition selection and rifle maintenance.
