K22 - I didn’t ask and I didn’t see in your original post how many shots were fired before you shot those groups? Did you go right to group shooting when you switched from S&B to RWS? Like I mentioned a new bore typically takes 20-30 shots for the best accuracy to show and typically 10-20 between types of ammo (including different lots). This is assuming that no other typical issues were the culprit (besides some of the common ones mentioned and I know you know what was the wind like). Don’t be to discouraged - it will shoot for you and I haven’t met too many .22s that weren’t a project of some sort!

I've heard that switching ammo requires several rounds to settle the barrel back in, but I rarely do that. I've noticed that it makes a difference but not as much as some claim, leastwise not in mine. Then again, none of mine are target rifles.
