How to Boresight a Crossbow Scope – Step-by-Step Guide & Tips

Boresighting a crossbow scope is easy if you know the steps…

Which we will cover in this article.

Let’s get started!

Getting Started

You’ll need your crossbow, a scope, a scope’s user manual, an appropriate screwdriver, a crossbow rest, four or more arrows, some kind of target, and binoculars.

You should attach your scope to your crossbow before shooting. Instructions are included in the user manual.

First Test

You will need to use a crossbow and a scope to shoot targets. Aiming through a scope is done by drawing back the string and seating an arrow in the flight rails.

Shoot the target with the tip of your index fingers. Check if you hit the bullseye by moving to check it, or use binoculars.

You’re aiming at the center of the bullseye, but you can also aim at any other point within the circle. The topmost dot indicates a target 20 yards away. Additional dots increase the distance by 10 yards.

Boresighting your crossbow requires realigning the flight rail to match the target. You can do this by using a rangefinder or measuring the distance to the target.

You must shoot your arrows into the center of the bulls-eye.

Making Adjustments

Adjusting windage and elevation refers to adjusting the distance to the sides and up/down of your crossbow. Your adjustments should be made based on the results of your test shots. Move the windage adjustment knob to the right if your shot was pulled to the right. Move the windage knob to the left if your shot was pulled too far to the left.

Most scopes will adjust by ¼” of an inch at 20 yds for each click you hear while turning the adjustment knob with a screwdriver (or similar tool). You can estimate or measure the distance from where your arrow hits to the bullseye to determine how much to turn the windage knob to get the desired aim point.

Elevation and Windage knobs are used to adjust the point of impact. The elevation knob raises or lowers the bullet by an inch while the windage knob moves the bullet left or right by 1/2″. Both knobs should be replaced after adjusting them.

Range Compensation Reticles

You should be aiming at a target at about 50 yards away. Your chronograph should measure the speed of your arrows at around 300 fps.

You must dial in the result, follow the instructions in your manual closely.

How To Sight a Crossbow?

When aiming for a crossbow, you need to know what kind of arrow you’re using. A heavier arrow will fly farther than a lighter arrow. Arrows weigh different amounts because they come in different sizes. To figure out how much an arrow weighs, use this formula: (weight of arrow) x 0.0045 pounds. For example, a 25-pound arrow weighs about 1/2 ounce.

Crossbows are weapons used by archers to shoot arrows. To sight a crossbow, you need to adjust the scope. You must know how to do this correctly. A beginner may think that there is something wrong with the scope, but in reality, it’s perfectly fine.

You should zero out the top dot or reticule for a specific distance. This means aligning the top dot or reticular for your desired shooting distance. Once you’ve done this, the other dots and reticles will automatically line up for their respective distances.

Elevation Windage Adjustment Knobs

There are two knobs on the sides of every scope. You use them to aim your crossbow.

Adjustment knobs are covered by protective plastic caps, which must be removed to make adjustments. There are markings on each knob indicating the direction you need to rotate the knob to adjust in a specific plane. Left-most photo shows elevation adjustments and requires turning clockwise to raise the arrow point of impact, and anti-clockwise to lower it. The right-most photo shows windage adjustments, which require turning clockwise to increase the right side of the sight and anti-clockwise when adjusting the left side. Remember to put the caps back on after you’re done making adjustments.

The adjustment knob clicks as you turn them. 1 click 1/2 inch at 100 yards.

A crossbow uses bolts or arrows to shoot at targets. Crossbows are used by archers to hunt games. You should know how many clicks you need to make before you can fire an arrow.

Step By Step Sighting Your Crossbow

You need to use a shooting aid when using your crossbow. Otherwise, your accuracy may suffer.

Basic crossbow shooting aid is a crossbow shooting aid.

Step one

You should aim at the center of the bulls-eye, then shoot three arrows.

The target was hit by 3 arrows. The arrows were placed too far to the right and down.

Step two

The distance from the center of the bull’s eye to the top of the bullseye is 3/4″ (19 mm). To get an accurate shot, you must adjust the position of your bow by 19mm to the left and down.

You will remove the protective cap off the scope adjustment knobs, and make the appropriate changes to the adjustments. We said earlier that a single ‘click’ of your adjustment knob will change the arrow’s impact point by 1/20″ if shooting from a 20 yards distance. We also determined that we’d have to move the arrows 1″ up, and 2″ right.

Here is what you do: Adjustment knobs should be turned counterclockwise to move them up or down. Turning them clockwise moves them to the left or right.

Step three

You line up for the shot. Align your top dot/reticles with the bulls-eyes. Shoot three arrows. The first arrow hits the center bullseye. The second arrow hits the outer left bullseye. The third arrow misses the target completely.

Four Things to Keep in Mind

Sighting a crossbow takes about 10-30 minutes. You’ll need to adjust the knobs until you get the right aim. When your skill improves, you’ll be able to shoot better.

You should always make sure to put the plastic caps back on the adjustment knobs after using them. If you do this, then you won’t ever lose them. If you don’t, then you might end up losing them.

Your crossbow should be aimed at the center of the target, and you should practice shooting until you can consistently place an arrow into the bullseye. You may need to adjust your scope or sight depending on how far away you are from the target.

Arrows are pointed straight ahead, but the person shooting them doesn’t know how to hold the bow properly. He shoots too far away from the target and misses every time. Tight groups are better than loose ones.

Please make sure to work a little bit on your arrow grouping so that your crossbow sighting procedure makes sense.
