Reset to factory settings

you can put a 11mmto weaver adapter,the put a tall ring set on the adapter. That will be pretty high.Now the idea is to keep the scope closer to the barrel for the trajectory, But you got to do whatever needs to be done! Happy shooting! Be Safe!

There are several potential problems that could be causing this. The most likely are:

misaligned rings
misaligned ring bases
misaligned ring base screw holes
Bent scope

other potential issues
bad scope
bent barrel
poor action bedding (putting enough pressure on the barrel that it throws the bullet to the right, unlikely)

The first 4 are most likely and can be checked by using a different scope. If you have the same issue with the new scope, then look to the rings and mounts as your probable issue.

this is a good guide:

this is an excellent article on zeroing a scope.

You will have to shim the scope, use a piece of 35 mm film, It works good, 2 if you need it, if you at extreme measures, you will have to shim the base. You can look through the barrel of a bolt action rifle and see what you will hit at 100 yards, just prop up the rifle in a box or a vise, site down the bore at a target, mailbox, streetlight, then bring the scope to that point, check your barrel again. This will put you on paper at 100 yards. Hope this helps.

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.

iv had this problem many times before,,,its more likley to be a bad set of mounts not inline with the barrel,,, if you have ran out of windage adjustment,, to get over it i use a strip of 35mm film inside the scope mount to push the scope over a bit,,, but a new set of mounts would be the best way forwards

Mount the rifle with the scope and make a mark on the backstop right where the crosshairs are pointed at

Shoot several times, several shots will surley jolt the scope some.

If the crosshairs have moved much past your mark then this would indicate the scope is the issue.

If the crosshairs are still pretty well centered to the mark, its not the scope.

If at the same time your grouping looks terrible, and your scope still is on the mark, and the gun is WELL mounted, then the issue is with the accuracy of the rifle.
Make sure the rifle is mounted good for this to ba accurate .
Hope this helps

Sounds like you want to "re-sight" in your rifle. Make sure mounts are okay and tight. Look down barrel and then thru scope and eyeball windage and elevation adjustments so the scope seems to be fairly in line.

Clean barrel if it needs it.

For basic sight in, start at 25 yards with a large(3 to 4 feet) cardboard or wood backdrop around target (bullseye). Fire at target. Once done, look through scope and position rifle such that the shot mark you created is dead zero. Hold rifle very steady and you or buddy move windage and elevation adjustments until scope moves dead zero back toward original target (bullseye). Fine tune from there. Air cool rifle between rounds. Once dead eye, fire another round or two to check grouping. Check your ballistics (sometimes on ammo box) to see how height at 25 yards affects your desired dead on target (100 yards, 150 yards, 250 yards etc.). Adjust accordingly. Example: you may need to sight in at an inch high at 25 yards, depending on your dead on target distance..

Always remove sling from barrel when sighting in.

Try to sight in at similar temperature as you intended shooting temperatures, if possible.

If not black powder, avoid cleaning barrel between sight in and hunt/competition unless you note bad buildup inside.

If you change ammo, understand that that may affect performance. Once a preferred ammo is found, some even try to buy a decent quantity with the same lot number on the boxes if storage allows for such.

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.
