Can I Trust My Zero Settings Over a Long Hunting Season?

Zero Retention and Maintenance

A well-maintained rifle zero can last for years, but it’s essential to check and adjust your zero regularly, especially if you use your rifle consistently over a long hunting season. This involves shooting your rifle at various ranges and checking the point of impact (POI) on your target. If your POI is off by more than 1-2 inches at 100 yards, it’s a good idea to re-zero your rifle.

Temperature and Environmental Factors

Temperature fluctuations can significantly affect your rifle’s accuracy, and humidity can also impact your scope’s reticle. It’s essential to consider these factors when shooting your rifle, especially in extreme environments. A temperature change of 20-30 degrees Fahrenheit can affect your rifle’s accuracy by up to 2-3 MOA (minutes of angle). This may not seem significant, but it can add up over time, especially if you’re shooting at longer ranges.

Zeroing Techniques

When zeroing your rifle, it’s essential to use a consistent and repeatable process. This involves shooting at a target with a known range and adjusting your scope’s elevation and windage until your POI matches the target. It’s also crucial to use a high-quality target and scope, as well as a consistent shooting technique. A good zeroing technique involves shooting 3-5 groups at different ranges and checking the POI, making adjustments as needed, until your groups are tight and consistent. This may involve re-zeroing your rifle multiple times over the course of a hunting season, especially if you’re shooting in different environments.
