WTM45 made to comment about scope settings and it may affect yours.
On my Excal I can adjust the velocity setting of my scope so as to match the bow. I had to sight in at 20 and then adjust the setting to get hold and impact t to match at longer distances.
Same type of setup with the Ravin optics. At least the 450FPS ones.
But the magnification is changed when the dial is moved to set for different trajectory.
Not sure if the locking ring 550FPS optic on the R29X is exactly the same, in that the magnification is changed.
