    Are you sure you are adjusting properly?
    Since you already twirled the knobs, you will have to start over and make sure your scope crosshairs are centered in the tube.
    1. Put the gun on a bench or vice or sandbags.
    2. Loosen the rings and look through the scope as you rotate the scope. Adjust elevation and windage until the crosshair center stays fixed as you rotate.
    3. Look through your iron sights and line the barrel down range to a spot at infinity.
    4. If the scope is not in the same spot or anywhere near it, the rings are out of alignment because the scope crosshairs are now centered with respect to the outside of the tube and the rings.
    5. Use your iron sights to point at a bullseye at about 50 feet. Make sure the scope sights in somewhere near the bullseye.
    6. Use the scope to shoot 5 shots aimed at the same spot on the bullseye. Don't chase the holes, just aim at the same spot for each shot.
    7. Steady the gun and point the scope to the center of the bullseye and while looking through the scope at the target, ADJUST THE CROSSHAIR TOWARD THE CENTER OF THE SHOT PATTERN, NOT ACCORDING TO THE ARROWS ON THE DIALS. Do this with the gun locked in the same position as much as possible. A gun vice works best, but pressing down on the gun using sandbags as a rest with one hand while dialing with the other is OK. DO ONLY ONE AXIS AT A TIME.
    8. Go back to step 6 and shoot again
    9. Once you are zeroed in at 50 feet, you should only have to adjust the elevation when going out to 25 yards or 50 yards. The windage should not have to move unless there is a stiff wind on the range.

    Just make sure it really is the scope that is bad. You certainly don't want to go out and buy a $100-$200 scope only to find out it was the mounts or the sighting-in process that was wrong.

      I am having some issues zeroing in my Tasco Walmart special scope and weaver rings for 22s on my new 795. Iron sights shoot just fine (I tend to shoot a bit to the right but I think that's just me) but with the scope I shoot about six feet low and a foot to the right. I have the elevation pegged all the way to its highest setting and all the way to the left (still shoots a foot to the right). I have checked the crown and it has the status quo "Its Friday at beer thirty and I want to go home" job. Would this cause the scope to be completely wacko but shoot fine with the iron sights? Help?
      Scope must be bad. Elevation is normally 1/4" per click @ 100 yds. At 50 yds it is 1/8". So 6 feet (72 inches) low means that you need to adjust the elevation about 288 clicks to get it to zero. There is not that much adjustment in any scope made on this planet. Take the scope back and get another. Walmart has the centerpoint scopes (I have one) and its decent for the price. Mueller is better but more expensive and not available at WM.
