You should not be having the degree of problems you are describing, and should at least be on the paper every time without any adjustment (if it was on last time you shot). Sounds like something besides the scope is off, like maybe the bases or rings are loose. You should be able to see the bullet holes with 9X at 100 yards with the scope too; did you adjust the eyepiece according to the directions and then lock it down? If all this checks out then maybe you need different ammo that the rifle likes better for accuracy.
