How to Zero a Scope – Easy In-Depth Guide with Tips, Advice, & More

How to Zero a Scope

How to Zero a scope is one of the most commonly asked questions when it comes to hunting and shooting.

Keeping in mind how important it is, we have decided to cover each and everything you need to know about zeroing your scope. 

So, let’s get started.

How to Zero a Rifle Scope

When you aim for your gun, you want to make sure that the bullet hits the target dead center. This is called zeroing your rifle.

You need to know how to zero a rifle before you can use it effectively. Read this article to learn about the basics of zeroing a rifle.

Point of Impact (POI) is the place where the bullet hits the target. Point of Aim (POA) is the place where you aim the rifle.

The turret is used to help you aim. They should be marked with hash marks and numbers. They should turn when you move them around.

A click means that you’ve turned the turret by one click. You should be able to feel each click. There may be some scopes that have more clicks per turn or some that have fewer clicks per turn. Most scopes have 0.1 mil clicks.

For example, if you’re using a .50-200mm rifle scope, then you’d use a turret that goes from -0.5 mil to +0.5 mil.

Whatever unit you choose, stick with it. Keep your units consistent so you don’t have to convert after conversions.

Bullets fired level to the ground will hit the ground at exactly the same time.

Gravity is a force that pulls objects towards the earth. We use this force to make things fall down. To aim at an object, we must first set our sights on it. Then we adjust the angle of the gun until the bullet hits the target.

MPBR is the range that a rifle can shoot with minimal angle change.

Deer hunting requires a lot of practice. You need to learn how to use a gun properly. A hunter must know what kind of ammunition he needs, and how to load it into a gun. He should also know how to aim and shoot accurately. And finally, he must know how to hunt safely.

This is also how military zeroes work, normally called Battlesights. 25/300-meter and 36/300-yard are the US Army and U.S. Marine Corps standards for 5.56mm NATO and work the same as an MPBR. An MPRB only works when you have good data and shoot the same ammo consistently.

You should always use the right ammo for your rifle. If you shoot a.30-06 M2 Ball cartridge, you’ll get a different result than if you shoot a.308 Winchester round. And if you shoot an ELD-X bullet, you won’t see any difference in accuracy than if you shot a standard lead core bullet

This is a 40 MOA 1911 rail on this Bergara.22LR rifle. For centerfire 20 MOA accuracy is pretty common, for Rimfire 20-40 MOAs can be found. You can’t really tell just by looking, but this is an 80 MOA 1911 rail on a Bergara.22LR.

Generally, I would recommend that if you want to shoot a gun, you should just go out and buy one. You might be able to borrow one from someone else, but there are probably many different types of guns available. Some people may prefer one type over another.

However, if you can’t get a gun, you could always use something else instead.

All of them are pretty quick but painful. Some people prefer them over others. I’ve tried many different types of scopes and have slowly built up what I like best.

The No Tech Method

Your rifle should be aimed at the center of the bullseye. You should shoot the center of the target when aiming. When shooting, your bullet should hit the center of the target.

Using a bipod and a rear pouch is the best way to get accurate shots. You should use a shooting bench, shooting rest, or bipods. Use whatever you want as long as you’re supported.

This method is very easy to do. You should aim to get a perfect shot at a target. If you miss, try again. When you’re ready, fire! Your bullet should go straight into the center of the target.

It takes a firm and steady aim. You must shoot at the center of the bull’s eye to make sure you hit the center. When you first start shooting, you might need to adjust your sights. After you’ve done this a few times, you’ll know what adjustments you need to make. At 25 yards, you should be able to move your target back to where you want your final zero.

Math and counting are used as a way to help people learn how to shoot better. This is a great way to teach someone how to use a gun without having them get shot.

For each adjustment, there is a multiplier. So, if you adjust by 1 MOA, then multiply by 4. You get 4×14 MOA. To add another adjustment, simply add the two numbers together. In this case, you’d add the two numbers together, which equals 8 MOA. Then, multiply by 4 again. This time, you get 16×464 MOA.

This method requires you to count out how many clicks you need to move the crosshairs over the target. So if you want to shoot at 100 yards, you’d need to count out 100 clicks. You then add or subtract those clicks depending on whether you’re shooting right or left.

The Low Tech Method

A boresight is an accessory used to align a firearm’s barrel to the point of aim. This allows for more accurate shooting.

There are many options for cheap laser sights. You can get them for as low as $20. We have tons of information about those here. Just follow the instructions and make sure you’re using the right type of bore sight.

How to Sight In a Scope in Steps

You need to zero your rifle before you shoot it. To do this, you’ll use a laser rangefinder.

  1. First, make sure your rifle is unloaded.
  2. Next, place the rifle on a solid surface.
  3. Then, aim the rifle at a distant object (like a wall).
  4. Finally, turn the power up to high and press the trigger.

A red dot should appear on the screen. This is your zero point. Now you’re ready to go!

Get on Paper With a Boresighter

Get your rifle on paper before you go hunting. You should use a collimator or laser bore sight to align your barrel and scope.

Boresighters help shooters line up their rifles quickly and accurately. This is done by lining up the bore of the gun with the center of the crosshairs. By doing this, the shooter can see exactly what he/she sees through the barrel.

After the adjustment, the shooter moves back to the starting point (50 yards) and makes another adjustment. The process continues until the dot appears perfectly aligned with the center of the target. At this point, the shooter is ready to fire.

Make Your Ammo Decision

Determine which load you plan on using before proceeding to the zero process. If you zero at 100 yards and plan to hunt with a different load, your point of impact might be off. You should also consider how far away you want to hunt. At 100 yards, you’ll get better accuracy than if you were shooting at 200 yards.

Shoot groups first. Don’t worry about being perfect until later.

A 100-yard zero is usually used when shooting at close range. When using a rifle, a 100 yard zero puts the bullet dead center at around 200 yards. This is the perfect distance for shooting dangerous game.

Use Good Shooting Technique

To get the most accurate zero you should be using a rest that doesn’t allow for any human error. You should also be taking your time when sighting in the gun. Your best bet is to use a rest that allows for minimal movement and to take your time when adjusting the sight.

When you’re shooting from a bench rest position, you should make sure that your rifle is properly supported by sandbags or other supports. You should also be careful about how much pressure you put on your rifle while aiming. Your supporting hand should be used to support the rifle, and your trigger finger should be the forward-most contact point. After firing a few rounds, you should check your rifle to see if it still holds zero.

Cold and Clean Rifle Barrel

A rifle scope should be adjusted when you first use it. After that, it should be left alone until you need to adjust it. Cleaning the barrel helps to ensure that the bullet hits the target. You shouldn’t change the zero after firing 20 rounds.

You should always check your zero before firing. Your rifle may have lost its zero while traveling.

Double Check Then Check Again

Bipods are great tools when used correctly. Some rifles won’t shoot well with them, though. When using a bipod, make sure to aim at the center of mass of the target.

You should check your zero before starting your trip. It may be hard to see your scope in the dark, so use headlights or flashlights. Don’t forget to check your zero before shooting.

How to Train and Practice Shooting Without Live Ammo

In this book, author Richard Nance teaches you how to train and practice shooting without live ammo. He also explains why you should never use live ammunition when practicing your marksmanship skills.

What is Zeroing?

When you buy sights for your rifle, you can’t just toss them on, aim and fire, and expect a bull’s eye. You must adjust the sights so your point-of-aim (POA) matches the point-of-impact (POI) at any given distance. This is called “zeroing” the sight. In other words, there will be zero differences between the two points.

To do this, you need to use a tool called a “sighting device”. A sighting device allows you to see exactly where your POA should be at any given distance. Sighting devices come in many different forms, but most consist of a front lens and a rear lens separated by some kind of prism. Through the lenses, you can see an image of the target.

The image is then projected onto the prism, which splits the light into two beams. The left beam passes through the prism and strikes the front lens, while the right beam goes straight through the prism and strikes directly on the rear lens. By looking through both lenses simultaneously, you can see where the center of the target lies.

Then, you simply move the front lens until the image of the target appears centered on the rear lens. Now, when you aim your rifle, the image of the target will appear perfectly centered on the rear lens, allowing you to accurately hit targets at any distance.

How does it work?

You need to first determine where the rounds are impacting (POIs). The best way to achieve that is by aiming at the center of a large paper target, pulling the trigger, recording where the round landed, then adjusting the sights if necessary.

If the round landed high and right of where you aimed, adjust the sights higher and right. This adjusts point of impact down and right to match the bullet’s actual impact. Basically, you should wind up aiming at the exact spot where your bullet actually impacted.



Reticles measure angles by using angular measurements. Adjusting POA makes a bigger change in POI when the target is farther away. This means that reticles work better at longer distances.

The size of the circle is proportional to the distance to the target, as you can see here. The angle’s width increases proportionally as distance increases. This means that if your target is 100 yards away, then the angle’s width is 2 inches wide. But if your target is 300 yards away, then the width of the angle is 6 inches wide.

A reticle is a device used by a rifleman or marksman to measure the horizontal distance between him and his target. It consists of two parallel lines marked off in inches. The first line represents the point of aim, and the second line represents the point of impact. When the shooter aims at a specific spot, he adjusts the position of the crosshair until it touches the top of the second line. He then fires.

MRAD Turrets

MRAD turrets provide 0.1 mils per click. How does this relate to actual measurements? A scope’s reticle can be measured by the number of horizontal and vertical dots, lines, or a gridded pattern. Subtensions are the exposed knobs located on the body of the rifle scope. They control the elevation and windage of the reticle.


Milliradians use the metric system. They measure distances in millimeters (1mm 10m) and angles in degrees (0°360°). In this case, the distance between the shooter and target was about 0.5mm or 0.05 inches.

A minute of angle is divided into 21,600 equal divisions. One MOA equals one inch at 100 yards. This means that one MOA is.25 inches at 25 yards, two inches at 200 yards, three inches at 300 yards, etc. In this example, you would need to adjust your aim up by two minutes of angle to close your two-inch gap at 100 yards.

Which Reticle Should I Pick?

MOA is the most popular reticle and turret combination for most shooters. It’s easy to calculate ballistic data in mils. Americans prefer using inches, feet, and yds over cm and m.

Zero Stop Turrets

Zero stops are used on rifles today because of ease of use. A zero stop allows the shooter to quickly adjust the gun to zero without having to move the turret.

Adjusting the Turrets

All scopes have turrets that move the POA left/right, up/down and in/out. Some scopes also have turrets that move the reticle out of focus. To achieve clarity, you should use the last two turrets.

This scope’s reticle has 1/2 MOA tick marks. Our rounds landed 3 MOA right, 2 MOA high. That means we need to adjust our scope by 3″ right and 2″. On a quarter-click, that translates into 12 ticks right and 8 ticks up.

A.25 MOA round lands about 5 MOA (or 1.25″) low and about 2 MOA (or 0.50″) left. That translates into 20 clicks down or 8 clicks left to zero point of aim. MRAD scopes have mil dot reticles. In this case, we used 0.25-mil suspensions.

We use our mil dots to determine the distance to the target. We then calculate how many clicks away it is. Then we subtract the number of clicks from the number of mils to get the distance.

This gives us the range. We also know the height of the target. We then convert the range to inches by multiplying by.001.

Windage Turret in a Videogame

The Windage Turret is a weapon in the video game Star Wars: Knights of the Old Republic. It was created by Obsidian Entertainment and released on December 12, 2007 for Microsoft Windows and PlayStation 3. The windage turret is one of the only weapons in the game that has an adjustable scope. When activated, the windage turret will rotate around its center axis until it reaches the desired position.

Zeroing Without a Reticle

The gun sight is replaced by a grid square. We use a different method to measure the distance of the target.

A rifle sighted target measures 1 inch or 1 cm square. You aim center mass, and then count the number of squares off-center. This tells you how far away your shot was from being dead on.

Tools and Equipment

A proper zeroing method requires a stable support, a solid bench, and a steady hand.

A solid rest is critical when zeroing your scope. You need a range that allows you to set up a shot at 25 yards and 100yards. Use a target that is large and easy to see at 100 yards. Have a grid pattern so you know exactly how to align your rifle.

A plumb bob is useful when aiming a gun because it helps you aim straight. You need to be careful though, because if you move the plumb bob too much, you might accidentally shoot someone else.

Bore Sighting

This seems like some mystical procedure. It is really nothing more than taking the upper receiver off your rifle and removing the charging handle and bolt assembly.

Set up the rifle using sand bags or a front rest and a rear bag. Anchor the rifle into place. Look through the scope. Is there an error in the reticle? Turn the elevation and windage until the reticle is aligned with the target. Make sure the rifle does not move during adjustments. Check again to be sure the rifle is still level.

When you’re using a rifle, make sure that the bore and reticle line up. This means that when you aim at something, the bullet hole should be right over the center of the target. For example, if you were aiming at a deer, you’d want the bullet hole to be over the heart.

First Shots

First shots should be made at 25 yards. Shooting at this distance will eliminate any errors caused by elevation or windage. All of your shots should hit something somewhere.

After firing the first shot, the bullet hole should still be visible. Turn the turrets until the reticule is centered over the bullet hole. Then fire another shot. The second shot should go into the same hole as the first.

Your group is too big. You need to adjust your scope.

Adjustments Along the Way

Your rifle is now ready to fire. You’ve already zeroed the scope and set up the scope to match your target. Now you’re ready to shoot.

Know Your Click Values

You must first determine how far apart your shots are going to be. Then you need to adjust the scope accordingly. A scope may have an engraving on the turret indicating the amount of clicks per inch. For example, ‘1 Click ¼MOA’.

That means that each click on this scope will move the point of aim by ¼ MOA. So if the group size is 2 inches low, then 8 clicks up will be needed to center the group.

This scope will move the point-of-impact 1/4″ for every click at 100 yds. Some scopes will have ¼ MOA adjustments. Some will be calibrated to move MILS.

MOA’s and MILS – What does it mean?

MOA is a unit of angle. At 100 yards, MOA is about 1″ tall. At 300 yards, MOA is 3″.

A shooter should always know what type of reticle he or she is using. In this case, the shooter should know that the reticle used by the gun does not allow for a 1/2-dot holdover. This means that the shooter must hold the weapon at least 1/2-dot higher than the distance to the target.

Why Zeroing a Scope Important?

If you don’t do this, you could end up damaging your gun.


You’re excited to use that scope, but you need to zero it out first.

Otherwise, you’ll think that your scope is junk when it’s actually working perfectly.

Hopefully, this guide helped walk you through everything you needed to know to zero your scope, and reinforced the importance of this process.

So, the next time you shoot, you’ll know that your scope is going to be perfect.
