When the hammer strikes it comes against the force of the air in the cylinder and lets out a slug of air. As the cylinder pressure reduces the hammer will let a bigger slug of air through.This results in a higher point of impact. This change shouldn't happen in a regulated rifle as the regulator should keep the pressure even!.
What regulator pressure is your gauge showing?
The way forward is to do a full chrono string with weighed pellets. Fill to 210 bar and record the shots.
