Every shooter must zero in their scope correctly if they expect to achieve high accuracy levels. This post will cover a few different methods on how to zero a scope at 100 yards, without shooting groups, and for a total factory reset.
Zeroing in your scope requires an active awareness of your environment and a functional understanding of the following factors:
Zeroing in your scope will help ensure that you’re not too far up, down, or to either side by using the correct number of MOA clicks.
As mentioned above, the process varies slightly depending on the type of firearm you have and your preferences (e.g., do you want to zero without shooting, or do you prefer firing groups?). Below are some of the most common ways to sight in a scope.
The most common way to zero a rifle scope at 100 yards is to use a trial-and-error method. This entails an approximate initial adjustment to start things off, then firing groups and making more precise adjustments based on your observations until you’ve got it right.
Follow these steps below to use this style of zeroing in:
You might not always have the opportunity to fire a few rounds as you’re zeroing your scope. (Or you simply may not want to.)
This process shares a few similarities with the one above. The main difference is that you’ll almost certainly need a laser. Without this tool, you’ll have quite a bit of difficulty sighting in without shooting.
Follow these steps below to conserve your ammunition while zeroing in:
Keep in mind that you may not need to install a laser separately. Lots of scopes come with a built-in laser, but they are often more expensive.
A time may come when you need to reset your scope to wipe your slate clean, essentially. You may have gone a bit too far with past adjustments, leading to excessive wear on the scope’s inner components.
If you suspect this is the case, try using the steps below to return your scope to its factory settings before zeroing in again:
Zeroing your scope is quite easy, even without shooting your weapon. All it takes is a sound understanding of how the windage and elevation work together when adjusted by the current number of clicks per MOA.
Refer to this guide the next time you’re sighting in for accurate shots (especially if you need to factory reset it to prevent excess wear).
