Sounds as if the rings are slightly misaligned.was it factory drilled and tapped or was it done aftermarket.A competent gunsmith can correct this with an aligning tube'or youcan try shimming the inside of the rings with plastic shims cut from a plastic bottle.I always used plastic because it is impervious to weather.Good Luck

SOURCE: Having Trouble Dialing in New Air Rifle Scope

I had the same problem.. shimmed the rear ring by folding some aluminum foil and lining the whole bottom part of the ring. I think after all was said and done, the aluminum was about 12 slices thick. This gave me a little bit of elevation to play with.

What that means is they are not mounted correctly. The scope mounts should be square with your rifle when fitted, when the scope is placed into the mounts, it should be turned to be square with the rifle.

Firstly, make sure you do not "cant" when you shoot. That is hold the rifle at an angle instead of vertical. Once you are sure that is OK, then put it into a vice using blanket or some other soft material to protect the stock. Get the rifle perfectly square using a spirit level. There should be a flat spot on the top of the action that you can use. Once this is achieved, you loosen off the scope mounts and square the scope up to your satisfaction. Once done, tighten the mounts up and then remove from the vice.

SOURCE: while sighting in rifle with new scope the cross

Is the scope moving in the mounts? Going back and forth, left and right? If so, tighten up the screws, Or are the stadia wires themselves spinning around inside the scope? That could be a problem. The wires are fixed in a tube that is mounted at the rear, the front is at the adj screws, they push back and forth on a spring, the whole tube moves, but it is not supposed to spin. You can get to this part easy enough, but go no farther than the cross hairs. Find out what they are supposed to be attached to, or just send the whole thing back and complain. If you break the seal, they will never honor the warranty if there is one. Hope this helps.

SOURCE: CAN NOT ZERO GUN

If your Roberts been rechambered or re-barreled or even a new rifle.
A common problem is the mounts are not true to the bore.
In theory the bore must be exactly in line with the scope/mounts, but in reality a barrel will shoot to the left or right of the scope/mounts.
If you zero @ say 100yds, (this is now a point of intersection, think of 2 straight lines crossing ). Now firing before 100yd the path is on one side of the intersection of 100yds and beyond it will be to the OTHER side of the 100yd zero.
What you need is Windage adjustable rings. There are number of companies that make these.
Set scope xhairs to zero. Dial windage all the way to the right, then count clicks all the way to the left, split the clicks to right and xhairs will be about on center. Now sight in scope using Windage on rings, finish to exact with xhair adjustment, but get it as close as you can with the ring windage adjustment, then your rifle will shoot "true" it's full trajectory because now your scope is in line to the bore. A very common problem with break barrel air rifles as well.

How to use redfieeld 3x9x42 scope


Depends on the scope and rifle type to which it is attached.
I invested in an inexpensive laser bore such as this one for an AR: SightMark AccuDot Laser Bore Sight - 223 Model SM39001 (for AR-15)
Once the scope is mounted properly, and assuming you have not made any vertical or horizontal adjustments, set the rifle on a stable platform, insert the bore sight, point it at a target 50 (rimfire) to 100 (AR) yards out (works best in low light situation).
Once you have the laser centered on your target, make elevation and windage adjustments as necessary placing the scope cross hairs over the laser. Remove the bore sight and fire 3 rounds, then fine tune elevation and windage.

How to sight in crosman extreme g1 pellet rifle scope


You would sight in an air rifle scope in the same manner as any other standard scope that you might find on a rifle:

You want to secure the rifle as best you can with the sights pointed towards a target, which should be set at the desired distance.

Reduce the error of your sight adjustments either by mounting the rifle in a gun mount or simply resting the stock (not the barrel!) on a solid surface such as a table.

Make sure that the weight of the rifle is carefully supported and the **** is firmly pressed into your shoulder. Looking through the sights, aim at the very center of the target (which for your purposes can be as simple as a piece of paper with a dot drawn in the middle).

Take time to ensure a careful shot, and be sure to avoid any shaking, utilizing the support of the mount/table (try resting the fore-grip of the stock on a roll of paper towels if you're having trouble keeping the rifle steady).

Once you are confident with the placement of the cross-hairs over the center of the target, gently squeeze (don't pull) the trigger.

Determine where the pellet struck the target, and adjust the scope accordingly; while every scope is a little different, the same basic principles for adjustment apply. Unscrew the caps on the top and side of the scope, and carefully read the markings on the adjustment dials.

If the pellet struck low, twist the dial on the top of the scope 'up' (the markings should specify clockwise/counter), and if the pellet struck high, twist in the opposite direction. If the pellet struck to the left or right, follow the same procedure for the dial on the side of the scope.

If the pellet struck low and to the side, make the vertical (up/down) adjustments first, repeat the shot, and only move on to make adjustments left/right once the pellet strikes in vertical alignment with the center of the target.

Take your time, and adjust in increments of only 2-3 clicks to start. Repeat the procedure until the pellets are striking consistently in the center of the target (if you're having a hard time remembering which shot went where, replace the target and continue.

Once you are satisfied with placement of your shot groupings on the targets, replace the dial covers on the scope.

Tips and Notes:
- In order to maintain the accuracy of your rifle, try to avoid resting the rifle on its scope and try to prevent the barrel from contact.

- Take note of your rifle's range, and be aware that the further away you place the target, the less consistent your results will be.

- Be realistic; don't attempt to sight in an air rifle at 50 yards. Remember that even with a rifle that has been professionally sighted, good results still come down to the accuracy of the shooter.

-Sight in your rifle at a range where you are confident in your own abilities; start with a closer target and only move back (i.e. sight in at a greater distance) if necessary.

CAN NOT ZERO GUN


You may try to bore sight it first. Pull the bolt and setting the gun on a good rest sight thru the barrel at a dot on the wall within ten feet. Then adjust the scope to that dot. As you adjust the scope tap the bore of the scope with a screw driver handle, tap it after each adjustment not hard, but enough to give it a sharp jolt. Once you are close here, move out to the range and shoot at 15 yards. Using a rest, again tap the scope after each adjustment. Then move out to 50 yards and you will want to be shooting high 1.5 to 2 inches here. Shoot slow keep the barrel cool and try for 2 shot groups till you have got the scope dialed in. Then move out to 100 yards for your preference of zero. Remember use the same ammo you will hunt with or at least the same bullet weight. If you can't get her to get on paper you can try to loosen the scope in the rings, one at the time once the gun is a little warm. Loosen the barrel ring first then snug it back down and then the receiver ring. If your group moved now, she was in a bind due to a cold gun at set up / installation.

the nikko stirling scope like most scopes has rubber "O" rings in them and they can go very tight on you at times all you can do is keep twisting it back and for till it frees off (it will in time) a splash of wd 40 mat free it off as well, but not very much if it gets inside the scope its finished

When adjusting for a couple of inches, the next shot is a foot off. It seems to wander all over the target.


! click is 1 inch @ 100 yards, provided you have the correct scope for the rifle.
If you are sighting in a .22 LR 40 grain match velocity bullet for 100 yards, the mid range trajectory (50 Yards) is 6" higher. The bullet has a 6" arc half way to your target. If you are sighting in a .270 with 150 grain blunt tail bullets for 250 yards, the mid range trajectory is .4 higher. It only has 4/10" arc half way.
You most match the scope to the gun, and the 1 click= 1 inch rule will apply. Otherwise, it's lock it into a righd mount, fire it and adjust the scope accordingly. If you want to change the range on the scope, it will be guesswork.
I use a Bushnell Banner 3-9X40 with BDC. If you have BDC, make sure you have the correct distance ring in for the caliber.. It will make all the difference in the world.

Hello,
I had the same problem but was able to solve it by shimming the scope mounts with a thin piece of plastic. Put it under the rear to raise the sighting and under the front to lower. I still plan to buy my son a better scope.
