View Full Version : How to Zero a Rifle Scope

Putting a scope on a rifle does not guarantee any accuracy unless you Zero it properly, this is how you can do that.

First of all you need to set a firm foundation by fitting the scope mounts and scope onto the rifle perfectly:

Put the scope mounts on the rifle first with the top brackets removed. Just like this:

http://img6.imageshack.us/img6/7568/83097355.jpg (http://www.postimage.org/)

Tighten them into place using 1/2 turns at the time so that they sit solid and level as best as is possible, i.e., the downward pressure is as equal as possible. At this stage don't tighten them fully as you might want to slide them up and down a little.

Now take scope and place it on top of the open rifle mounts.

Position the eyepiece by sliding the scope back and forwards. You may have to move one or both rings to get this right.
Position the rings so the scopes eyepiece will be the correct distance from your shooting eye when the gun is held naturally.
This is usually between 2 and 3 inches from the eyepiece lens, but it is the spot at which the image in the scope appears as full and bright as it gets.
To see what this looks like, move your head back and forth along the stock, as you look through the scope with both eyes open.
Then, position your head on the cheek piece where you want it to be and move the scope back and forth until the image appears bright and full.
Make sure the windage and elevation turrets are positioned correctly - Elevation (up and down cross-hair adjustment) on top and windage (left and right movement) to the right.


Then put the top mount brackets on and tighten - Tighten them until the scope is held secure but can still be rotated with your hand (Not very tight)


Now align the vertical cross-hair with both eyes open and the gun held naturally to your shoulder. Rotate the scope until the vertical reticle seems to bisect the gun perfectly.
OK? Yes - Now tighten the base of the rings securely to the gun top (NOT the top rings yet, that's next)


Now it's time to tighten the top cap rings. You need to take this carefully and slowly as it's a critical step. It's not hard, just be patient.
Tighten each screw partially, then move to the next one and go around the pattern of screws many times, rather than tightening each screw all the way on the first try.
You will put even tension on the caps and be less likely to dent the scope tube this way.
If there are two screws on the side of the ring, tighten only one, then tighten the one on the opposite corner of the other side of the cap (see graphic below).
Leave the other two screws for the moment and tighten two screws on the other ring next.
Then come back to mount one and tighten the two screws you left loose.
Then back to the other ring and keep rotating until the scope is secure.
It takes less tightening that you might think. They need be firm not as tight as possible. Err on the side of too loose, rather than too tight.

This is the order of screw tighten in the case of a double screw mount. If you have a single screw each side then do it as 1 - 4 - 5 - 8 (you get my drift I hope) basically you want pressure to be as even as possible throughout the process and not risk damaging the tube of having uneven pressure on one side that will make zeroing more difficult.

Air rifles can be zeroed in by shooting at a pellet target card or card in a trap at only 10 feet.

To do it this way you MUST wear safety glasses and ricochets ARE going to happen 100% definite. Also make sure that anyone else with you has them on too.

If you don't have safety glasses get some! If you don't and are impatient to get going (sighs) then try this method but extended distance to 30 feet or more.

Now it's time to zero the scope for shooting:

1- Adopt your standard prone/lie down shooting position.

Prone is the best way as if you test shoot from standing or kneeling positions you waver more and it's harder to do a "true test".

Make sure your windage and elevation turrets are ready for adjusting i.e., caps removed.

2- Draw 1 or 2 small dots on a piece of cardboard about 6.5cm apart vertically.
There's no precision to this step. You just want enough room on the target so no shots are lost. At 10 feet, they can't go too far.

If your scope has parallax adjustment, adjust it as close as it will go. If it has variable power, adjust it as low as it will go.

The aim point will probably be a little fuzzy at this distance.

Aim at the top dot. Expect your first shot to be as much below the dot as the center of your scope is above your gun barrel. If that's 7cm then that's how low the shot should go.

Then take another shot using the same aim point - this is to confirm the aim point as good as you can.

http://img6.imageshack.us/img6/9521/30123263.jpg (http://www.postimage.org/)

3 - Keeping in mind where your first 2 shots went adjust the windage and elevation turrets .
At only 10 feet this will take a lot of clicks.

Your objective is to get your shots in line with the lower target dot. Keep shooting and adjusting until you get there.

http://img6.imageshack.us/img6/6364/15008467.jpg (http://www.postimage.org/)

4- Now it's time to get serious. Move the target out to 10 metres (33 or so feet)
Take more shots and see where they land.

In this example they went off to the right a bit too much so adjust the windage (left and right) dial and few clicks - not so many are needed at this longer distance. Experiment.

http://img6.imageshack.us/img6/1134/68380807.jpg (http://www.postimage.org/)

5- One you're aligned correctly at the horizontal level at 10 metres it's time to get the vertical zero sorted out.
Your shot pattern should look like this now (see point 4)

At longer distance your shots will rise but stay in line side to side.

http://img6.imageshack.us/img6/9489/80307909.jpg (http://www.postimage.org/)

6- Now move the target out to 20-30 metres and shoot 5 shots.
If you know what your standard - average shooting range is then set your target at that range.

They should all be pretty close on the top dot now.

Make any small tweaks to bring them closer to the dot and you're about done.

http://img6.imageshack.us/img6/8518/52915667.jpg (http://www.postimage.org/)

You now know that at less than this range your shots will fall lower than the aim point so you can mentally adjust your aim to compensate.

Also, at about 5 metres further away the pellet will again fall lower than the aim point, so you can adjust again.
It's trial and error basically but with testing you'll get to where you need to be and be able to trust that your shots will go where it says they will! This may take some time and a lot of shots. Be patient!

A TASCO 3x9x40 should do the trick @ Rs. 3,000 - 3,500.

Is it available here, and does its manual mention it to be an air rifle scope? Many people are not aware that powerful spring air rifles like the Shadow 1000 are actually capable of damaging scopes which are built for magnum rifles, due to the unique recoil action of the air gun. If it is not specifically made for air rifles, it might work on lower powered ones, but will soon get damaged by the more powerful ones.

I've gone through a couple of scopes on the Shadow 1000. Despite all the careful tightening and zeroing, it was only able to hold up for a few shots (~10-15) before going off zero.

Btw, what kind of reticule does the Tasco have (simple wire cross, Mil dot, Duplex, etc)?

People might have bad experience with it but I have three in use for more than a year now and not having an issue with any of them. One is on a .22lr rifle as well.

nice to see people have good knowlde of scope on this forum

there is one small loop hole that can realy help you zero you high power sniper rifles and tahts call bore sight zeroing
after doing this you weapon will not be 100% zero but you can save 5 rounds out of 10 to zero it at bulls eye

how after mounting the scaope as the author has told you take out the bolt of your weapon
place the weapon at a firm fixture
take a thread and a tape and make a cross on the end of you muzzel with the thread this is a critical part so it has to be done almost perfectely


once you have managed to do that view at the bulls eye placed at 100 meters through the barrel place the rifle in such a way htat the cross of the thread on the barrel ends are at the bulls eyes
now view through the scope

most prob its crossair is at some other place
using the diles of the scope bring that on the bulls but remember do not move the rifle even a micro mm while doing all this
once you have done it and the cross of the muzzel and the cross of the scope at at same place shoot chance are that your shooting very very close to the bulls which you see in you scope now you can zero it using the authers way it will save you time nad ammo

DK, how about placing a small toy laser light in side the barrel and then view it from the scope, this will be more advance and effective too, isnt it?

KageFox

might work on high power guns, but I think not on low powered rifles and airguns

Unless using the boresighters similar to the ones below, the process explained by darrakhan works for bot-action rifles (by removing the bolt) and break-barrel shotguns (for dot & holographic sights). This process will not work for semi-auto or automatic rifles, pump-action or semi-auto shotguns.

Chinese scopes usually loose their zero after only a few shots. There lenses are also not top of the line, they are pok for .22 as it has a very low recoil. You get what you pay for.

Some one said we invest in 100K gun but want a scope for 3K only, rather it should be the reverse, and the results would be far better than the first combo.

No toy laser sight will help you as they are all (almost) off-centered.

@Conleal Carry... Suggestion of a TASCO (Chinese) scope was in context of KageFox's specific requirement for his airgun. Considering the guns value, effective range & application, I don't see any better suggestion. If there is, kindly update us. As for loosing zero, I have been with these scopes for hundreds of bullets & thousands of pellets.... they are still as perfect as new. This is my personal observation & experience.

I checked out the Tasco scope (Rs. 2500) vs a Bushnell (Rs. 7500). There is no comparasion. The clarity alone is worlds apart.

Thank you Abbas and everybody for appreciation. I'm glad that members took interest.

I once had the opportunity to look through an original SWAROVSKI scope, and believe me they are the greatest. Their lenses are the best in the world, followed by Leupold and Bushnel.

Check out Schmidt & Bender and Kahles sometime, you will be pleasantly surprised. Once you have seen through the premium European brands, you will not want anything else ever again.

German scopes including Schoenfeld , Schmidt & Bender, Kahles from Austria are among the top but Swarovski from Austria is way ahead of them all, no wonder they sell for US$ 2000 ~ 3000.
