Seems to be vertical stringing. Almost like two levels, an upper and lower There are a few things that cause this. Rifle grip or scope/mounts that are loose or broken are often the culprits.
I see the same thing with the two groups.
I wonder of the lower group are the first shots and and the upper group is with a warmer barrel?
And yes, the first thing I would try is to pull the scope and mounts off, check them closely, and remount the scope.
