The rifle has been dropped. now the windage and elevation adjustment is all over the place, however when it is finally zero, it holds its setting well, how can i fix this myself
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.
Sorry, its been awhile and its past midnight: After you shoot the first mark, hold rifle steady on original bullseye, and you or buddy move scope toward the shot mark. Once aligned, re fire at bullseye and you should be very close.
Alway shoot rifle same way, as vibrations need to be same. So no matter the rest always put your hand under forearm and/between what it is resting on, unless your always shooting off a bench-rest, then use same bench-rest always.

1. Insert the Bore Stud into the Stanchion while aligning the arrows as shows. Insert the assembled scope guide into the muzzle of your rifle with the grid pattern upright.
2. Select the Aperture Cap that fits your objective rim. Place it over the objective end of your rifle scope and press until it fits flatly against the rim.
3. Using the Adjustable Scale measure the top of your rifle scope tube to the center of the rifle bore as follows: Open the rifle breach. Rest the upper arm of the scale on the scope tube before or behind the windage and elevation turrets. The scale markings should be facing towards you reading vertically and ascending from bottom to top. Slide the lower end of the scale up or down until it is touching the center point of the bore. On center fire rifles the center point will be the firing pin. On rimfire models the center will be the shell extractor. Read the number that corresponds to the indicator marked "CF". Make a note of the reading.
4. Aim the rifle toward a light, flatly lit area such as a wall or open sky. Caution: Do Not Look At The Sun As Permanent Eye Injury Could Result.
5. While keeping the riflescope at the right distance to see the full field of view, sight through it on the grid pattern. Move the stanchion right or left until the bold centerline is parallel to the vertical reticule wire. Turn the windage dial right or left until the vertical reticule is aligned with the grid centerline.
6. Use the reading from the scale to align the horizontal reticule wire. Find the numbered horizontal grid line that corresponds to the number on the scale. Turn the elevation dial right or left until the horizontal reticule wire aligns with this corresponding grid line.
7. To make your final zeroing adjustments remove the scope guide from the bore of your rifle.
WARNING: FIREING YOUR RIFLE WITHOUT REMOVING THE SCOPE GUIDE MAY CAUSE DAMAGE TO YOUR RIFLE AND OR CAUSE YOU INJURY
At a range or other safe area test fire a group of three rounds of the same type ammunition at a target at least 50 yards away. Refine your scope alignment by adjusting the windage and elevation dials. Move to your desired distance from the target and test fire another group and make your final windage and elevation adjustments.
8. Restore the stud tension by pressing the end of the spring.
