Now we have for you a solution and it's free.
Quick Zero Tool

I designed the Quick Zero tool with air gunners in mind. This is a very simple approach to zeroing your air rifle and scope in less then 4 shots. Yes less then 4 shoots. Just follow the following instructions. It works with all air rifles, rifles and pistols irrispective of power.
The important is to know the scope MOA see on turrets or scope manual.

1. Identify our scope MOA. There are 3 kinds available 1/2" MOA , 1/4" MOA and 1/8" MOA.
2. Download the reference table according to your scope (below).
3. Decide on the zeroing distance. Normally 35 meters is standard zeroing range for FT and HFT or 25 meters for BR.
4. Set up a target with one point of aim at the zeroing distance, measure the distance with a measuring tape or a range finder.
5. Set up your air rifle on a bench and use a good rifle rest.
6. Make sure that your pellets are weighed in. Pellet weight difference changes POI.
7. If you are zeroing a PCP make sure it is zeroed at the Heart of Fill when it gives the most constant shots.
8. If you mounted a new scope center the turrets. Turn the turret in one direction until it locks, start turning the opposite way and count the number of turns until it locks. Then divide by 2 and place the turret in the middle.
9. Now shoot a group of 3 shots aiming at the aim point of the target.
10. Go to the target and measure in centimeters the vertical offset from aim point (Elevation) and the horizontal offset from the target (Windage) and take note of the are above or below the aim point and to the left or to the right of the aim point.
11. Go back to the bench and take out the Quick Zero Sheet.
12. Lets work on the Elevation. Find the nearest offset in centimeters in the offset column.
13. From the zero range columns find your zero range and move down the coloumn until you interest on the offset distance. Read that number. That is the amount of click you need to click your elevation turret to go on target. If your point of impact was higher then the target then you need to move your turret down, if your point of impact was lower then that target then you need to move up.
14. Identify the Elevation turret and start clicking in.
15. For Windage repeat steps 12 to 14. Remember if your shots fell to the left then you must click to the right and if the shots fell to the right of the target then click to the left.
16. Once you set the turrets, shoot an other group and your pellets will strike the point of aim.
17. If you want to fine tune go an re measure. The charts allow you to fine tune up to 1mm but this depends on the scope type and scope MOA.

Download 1/2" MOA Quick Zero Chart

Download 1/4" MOA Quick Zero Chart

Download 1/8" MOA Quick Zero Chart

Scope 1/8"MOA
Zero Distance 35 meters.

3 Shot group measurements from target center.
Elevation 5.5 cm high
Windage 6.75 cm left

Elevation 45 clicks DOWN
Windage 55 clicks RIGHT

The tool ranges for offsets from 0.05cm to 15cm. Should your point of impact is offset more then these value with centered turrets then it is advisable to shim your scope first, otherwise you can be too much off the central focal point of your scope.There is no magic this is all mathematics based on the MOA principles. I hope you will like this tool.
