How to Zero a Scope: a Beginner's Guide

07 March 2025, EuroOptic|Scopes

A riflescope can be a game changer when it comes to increasing accuracy and providing a clear view of your target–if you zero your scope properly. Zeroing a scope is kind of like tuning a guitar, making it an unskippable step if you want to really make music in the field. For new users, zeroing a scope can be a bit confusing. Read on to learn the basic steps of how to zero a scope.

Consider Ammunition and Bore Sighting

When zeroing a scope, use the ammunition that you plan to eventually use in the field. Different types of ammunition will have different trajectories, depending on projectile shape and weight, gun powder volume, and more.
﻿
If you zero in a scope with one type of ammunition but then switch to a different type, you will likely discover that accuracy may be off.
﻿
Another important consideration is the option to just use a laser bore sighter, which is perhaps the fastest way to zero a scope. In short, this process involves aligning your scope with the help of a laser. If you don’t have a laser bore sighter, you may be able to take your riflescope to a local sporting goods store and ask them to help you. In lieu of a bore sight, you can easily zero a scope on your own.

Mount Your Scope and Head to the Range

Ensure that your scope is mounted properly and determine where you will go to zero it. You’ll want to go somewhere where you can safely shoot and evaluate your accuracy, like a shooting range. A bullseye-style target will be particularly helpful. Wherever you go, be sure to follow the rules and regulations of the range you visit. 
﻿
Zeroing a scope at 100 yards is a good place to start. Set up your rifle on a shooting bench, on a bag, or otherwise arrange it so that the weapon stays steady, eliminating the possibility of user-error. Magnification is not important when you zero a scope, so choose a magnification level at which you are comfortable.

Take Test Shots and Adjust as Needed

Take Test Shots and Adjust as Needed

Load the rifle, and take three test shots. Three shots are enough to confirm that the first and second shots weren’t just a coincidence; if all three are in roughly the same spot, you know that’s an accurate reading of the scope’s current configuration.
﻿
Evaluate the accuracy of your shots, using binoculars if necessary. Now you can adjust the elevation (the vertical adjustment) and windage (the horizontal adjustment) of your scope using its turrets. Refer to the manual of your specific scope to determine exactly how to use the turrets or otherwise adjust. Usually it’s a good idea to adjust the scope in small increments each time, potentially just a few clicks of the turrets.
﻿
Repeat the process until you’re satisfied that the scope is zeroed properly. Continue to take three shots, safely examine the target, and adjust the turrets. Consider zeroing the scope from multiple distances–specifically the distances at which you are most likely to shoot. Always keep range safety in mind as you move about and configure at different distances.
