Quick Answer
When zeroing a rifle under field conditions, it's essential to use a consistent method, account for temperature changes, and verify your results with multiple shots. Start by ensuring your rifle is properly sighted in and adjusted for your specific optic and ammunition. Use a shooting bench or a stable rest to minimize movement.
Finding a Suitable Zeroing Location
When zeroing your rifle under field conditions, look for a flat, stable area with minimal wind and no obstacles that could interfere with your shots. Ideally, this location should be at least 100 yards away from any potential obstacles, such as buildings or trees, and should have a clear line of sight to your target. If you’re in a dense forest, try to find a clearing or a spot with minimal foliage.
Understanding Temperature and Elevation Changes
Temperature and elevation changes can significantly affect your rifle’s accuracy, so it’s crucial to account for these factors when zeroing. For every 10 degrees Fahrenheit change in temperature, your rifle’s zero will shift by approximately 1 inch at 100 yards. Similarly, for every 1,000 feet of elevation change, your rifle’s zero will shift by approximately 3.36 inches at 100 yards. Make sure to adjust your zero accordingly to ensure accurate shots.
Using Multiple Shots for Verification
To ensure accurate results, use multiple shots to verify your zero. Take three to five shots at your target, making sure to adjust your aim between each shot to account for any movement. Once you’ve fired the required number of shots, measure the impact points and adjust your zero as needed. It’s also essential to verify your zero at different distances to ensure your rifle is accurate at various ranges.
