I hope all of doing great
I have Diana chaser rifle kit it's awesome gun accurate and lightweight but I have an issue with scopes
The thing is no matter what scope I used  same thing happened ( I don't the problem is my gun or just me 🤔) okay so I have 4x20 scope you know the light ones that also cheap as well also I have borrowed my brother scope ( hawke 3-9x40) also I bought new victo 2-6x32 scope
All three scope the same thing happened
What happened is when I shoot from 10 m I adjust the scope on bullseye and I hit the target very well like 4 pellets within (1/2 or 3/4 in) but when I move further and shoot from 20 m the pellet hit above the target about 3.5 inches !!!!! Also at this distance the pellet group is good as well ( about 1 inch 3 pellets) but as I said it goes higher And as I told you this thing happened with all 3 scopes
In my knowledge the pellet should goes lower as the distance is farther but what I am experiencing here the pellet go higher!!???

So what I missing here?

This sketch shows what other replies have shown, basically the gun is tilted up if the zero is at 10 yards (1st) zero, then the pellet sails above the zero at further distance till the pellet falls to the 2nd zero, and the pellet continues to fall past the 2nd zero IF the gun is shooting "on the level"...............


I purposely sight in my springers at or within about 1/8" of the apex of the pellet flight, then I only need to "hold over" at all distances closer or further than my zero (LOL, that way I don't need to also remember "hold under".........
When I used a .177 R9 with 7.9 grain CPLs at 900ish fps using a 4-16x40 Bushnell Elite 4200 I found that a I had a near zero at 16 and far zero at 50 yards. When practicing at my brother's place for field target we would shoot targets from 10 yards to 55 yards using only "hold on" or "hold over" using symbols marked on pvc tape stuck to my AO............


Most ft marked their AO or side wheel with actual "sharp focus distances" and referred to a "dope sheet" to know how many clicks up or down to set the scope for each shot...........

Since I only shot hunter class field target "clicking on" wasn't allowed so all aiming was done using "hold over or hold under", plus my brother and I would hunt squirrels in the West Virginia woods using our .177 R9s we continued using only holdover for practice. Also, we would stalk within our "near/far distance zero" so there was no need for using a "cheat sheet" to be within a "minute of squirrel head" accuracy. LOL, at this distance most squirrels wouldn't give us the time to consult a "cheat seat" and "clicking on" before they scrambled away!

We used to shoot at field target course outside Harrisonburg, Va  that ft range would occasionally arrange pest control shoots at local farms. My brother and I attended one of those pest control shoots and at the end of the day there were bunches of starlings and English sparrows taken by the half dozen THAGC members that attended. My brother and I took over 1/2 of them using holdover. LOL, one of the attendees using his high zoot field target rig and dope sheet told us that he would set up to take a shot and see a puff of feathers through his scope where my brother or I already hit the bird by simply using holdover.

Anywhoo, the first task in setting up you scope is to shoot a target from 10 yards to about 50 yards and shoot several pellets at a bull from each distance using your preferred zero. Years ago I made up this target using a CAD program................

Here is the result of my shooting 5 CPLs at each bull using my 30 yard zero. I wasn't oo concerned about the tightness of the groups, only an approximation of the needed holdover at each range.......
