Before you delve into setting a crossbow scope, you should get to know what it is made up of, to make your journey an easy one 

Components of A CrossBow Scope

The crossbow scope has dots, reticles, elevation, and windage adjustments which help in making striking a target an easy task

Dots And Reticles 

They are located inside the lens of the scope. When you look through the scope of your crossbow, you would see some lines, dots, or patterns. They are the marks used by shooters in measuring the distance, aiming, and pointing to the target. 

To differentiate between the two, the dots are the red dots, while the optical scopes are the reticles. 

There are majorly two kinds of dots. The single red dot is represented at 20 yards. However, when you may want to shoot a distance longer than 20yards, you will have to hold the dot higher. 

The triple red dot is the kind of red dot scope used for long distances. It works perfectly well when there are elevation, wind, and movement situations. 

The reticle on the other hand has different types. 

The basic reticle spots about  20 yards distance. It has crosshairs that show when you need to take a longer shot if moved upward. 

The Multi / Truplex reticle has tiny dots located at the crosshairs’ intersection. The scope aids your aiming. Also in terms of crosshairs, it has horizontal and vertical crosshairs. 

The focal plane reticle, also known as the mil-based reticle is popularly known as a tactical scope. It comes as both first and second-place reticle. 

Also, there is the Bullet Drop Compensating (BDC) reticle, which is mostly used for its external, weather, and accuracy features. 

Elevation and Windage 

They are found in a close section of the scope. Again, when you take a look at your scope, you’d see some adjustment knobs that are covered by caps for protection purposes. Within the caps are the elevation and windage adjustment options. 

Look closely at the side, you’d find the windage knob. It is used for making the POI (point of impact) move either right or left directions. 

Also, take a look at the top of the scope, you’d find the adjustment knobs for elevation. It helps the shooter in adjusting the bolt of the crossbow’s point of impact in upward and downward directions. 

The Adjustment processes of An elevation and windage. 

Remove the caps covering the knobs and turn them in any direction. In doing so, you’d hear clicks. Each click helps in telling the archer how far they have gone in the adjustment. The clicks are usually expressed in MOA( Minutes of angle). 

How to Calculate The Click of Windage and Elevation

When you turn the knobs, one click shows that it has adjusted for ¼ inches at a distance of 100 yards. Therefore it means that one click stands for 1/20 inches at a distance of 20yards. 

 

However, this calculation varies from scope to scope. It is therefore advised to go through the instruction manual of your scope properly before you start your adjustment.

When it comes to reading the lines on a crossbow scope, the first thing you should know is that in most scopes, the first line is usually 20 yards distance. For such scope, the next line will be 30 yards, because scopes increase at a range of 10yards. Therefore, the formula is Line1 =20 yards, line 2= 30 yards, line 3 = 40 yards, and so on. However, some scopes are calibrated differently following a certain speed. For a bow that shoots at a range of 350 fps, 30 yards would be 27 yards. This is majorly because of speed frequency.
