Remount the scope and get the shot on paper at 20 yards moving it to zero as suggested.
Shoot several groups at the highest magnification, if a variable magnification scope.
Switch to the lowest magnification and repeat. The shots should group in the same place. If not, it may be faulty.
Yse a bench and be careful that you are not canting the rifle to one side or the other.
Another thing to check is that the scope rings are not up against the adjustment knobs as sometimes they can deform the tube resulting in really screwed cross hairs.
after you get the scope try different brand of ammo as certain rifles are sometimes fussy. If you are getting decent shot groups, that is a triangle, but too open for your likes , it is time to switch ammo.
I have a 10-22 and it loves CCI mini mags and Blazers but will throw some other brands all over the place.
