Zeroing a rifle scope, also known as "sighting in," is the process of ensuring that the scope aligns with the rifle barrel, enabling the shooter to accurately aim at the target. Here are the basic steps for quickly zeroing a scope:

Preparation: Make sure your rifle is stably positioned, preferably using a shooting rest or other support to minimize movement.

Initial Shooting: In a safe shooting area, set up a target at a fixed distance (usually 100 yards). Shoot several times to determine the current calibration of the scope.

Adjusting the Scope: Based on the results of your initial shooting, adjust the scope's horizontal and vertical knobs. These knobs usually count in clicks, with each click corresponding to a specific angle change.

If the bullet is to the left, adjust to the right.

If the bullet is to the right, adjust to the left.

If the bullet is high, adjust downward.

If the bullet is low, adjust upward.

Repeated Testing: After making adjustments, shoot again and observe where the bullets land. Repeat this process until your shots accurately hit the center of the target.

Remember the Settings: Once the scope is zeroed, remember the current settings for quick adjustment or verification in the future.

Practice and Verification: Practice shooting at different distances and under various environmental conditions to verify and familiarize yourself with your scope settings.

Please note that safety is always the primary consideration in shooting activities. Ensure that all applicable safety rules and legal requirements are followed when performing these steps. If you are a beginner, it's advisable to do this under the guidance of someone experienced.
