Quick Answer
Maintain the zero on your hunting rifle after a trip by checking the sight alignment and trigger pull, then shooting a few rounds to verify the accuracy. This process typically involves checking the scope's reticle and ensuring the rifle is at the same temperature as when it was previously zeroed. If necessary, make adjustments to the scope or rifle.
Re-establishing Sight Alignment
When you return from a trip, it’s essential to re-establish the sight alignment on your hunting rifle. Check the scope’s reticle to ensure it’s still properly aligned with the rifle’s barrel. This can be done by looking through the scope and identifying the crosshairs or reticle marks. If necessary, make adjustments to the scope’s windage (left-right) or elevation (up-down) turrets to re-align the reticle with the rifle’s barrel. Typically, you’ll want to make small adjustments of 1-2 MOA (minutes of angle) at a time.
Trigger Pull and Rifle Temperature
Before re-zeroing your rifle, ensure the trigger pull is consistent and the rifle is at the same temperature as when it was previously zeroed. A temperature change can affect the rifle’s accuracy and zero. Allow the rifle to acclimate to room temperature (around 70-75°F) for at least 30 minutes before shooting. This will help prevent any temperature-related issues that may affect the zero.
Re-zeroing the Rifle
To re-zero the rifle, shoot a few rounds at a target or a zeroing board, using the same ammunition and conditions as when the rifle was initially zeroed. Check the impact points to see if they’re on target. If the shots are off, make adjustments to the scope or rifle as needed. Start by making small adjustments (1-2 MOA) and check the impact points after each adjustment. This will help you re-establish the zero quickly and accurately.
