Good, standard picatinny rings RTZ very well when mounted correctly and torqued the same each time.
This was testing RTZ last year for a back up scope. Warne Mountaintech rings. 5 shots pre removal.

Then 5 shots removing the scope between each shot, and only using a witness mark to reattach- not torquing correctly for the first 4 shots. The far right shot was not even looking at the witness mark, just quickly screwing it on and tightening.

But, the Hawkins pic rings did not RTZ by witness mark. 5x shots on top of the red square before removing, then removing scope and reattaching. 5 shots 1 MOA/.3 mils to the right.

In this case, it may have legitimately been the scope with stress that was changed when mounting and remounting- I don’t know. But, for this hunt the Hawkins which hold zero well, were on the rifle, and the backup scope was in the MountainTech rings.
