Scope out of dope

The scope isn't aligned with the bore.

What scope do you have on the rifle?
What rings are you using?
How are you sighting in the rifle?
What torque setting are you using for the rings?

There could be a few things that are causing your problem. Need to narrow things down to track your problem.

When shooting are you getting a group, or are you scattered?

First look at the barrel's crown for dents, burrs, abuse and if shrouded, concentricity with the shroud, etc. Then check out the barrel liner itself for straitness. Look down the chassis to see if the barrel tip point to the right and the scope rail strait. If all is good there, maybe swap the orientation 180° on the two scope mounts to see if anything changes.

so just my experience.. rws 34 and a rws 48.. this was probably 30 years ago, but it wouldn't work at all.. I actually ran out of windage and elevation.. plus the scope moved.. these were both springers which is what I assume you have.. back when rws was all made in Germany..
I don't remember what the mount was called but it was like a one piece clamp with the rings built in.. and so you mount base with I think it was clamped full length of the rail.. with pretty big Allen wrenches.. then a set type screw went into a recess on the rail.. then you mount the scope and have the recticals center like factory.. then there are other Allen screws that allow you to adjust the scope so you are hitting really close.. then tighten it up and just use the scope for fine adjustments..
it's been so long ago I don't remember what it was called but I think it was a rws product.. so to be clear the rings were both on the same one piece and then the clamp was under it and adjust with Allen wrenches..
maybe someone else will chime in and just know what it was called.. I also remember that the rws 34 seems like it had a lot of barrel droop and this part will adjust to compensate..

I've got one of those sitting in my airgun shed. I think I remember it being called a RWS C mount. I bought it back in around 1992 for a rws 34 .177.

Is that a Beeman _S_500, a spring piston breakbarrel? If so your barrel might be bent. Fortunately, it is easy to bend back more straight, or so it points in a more helpful direction. Look up "bending a barrel" or ask here.

If the mount or bases can be reversed try that. Meaning if the screw heads are on the right can you turn it so they are on the left. I have had that work. Only other thing if the gun is not damaged many scopes have less windage adjustments than elevation. If you roll the scope so elevation becomes windage you might make it. No, I never did it but I saw it done and with a very high priced scope.
