I'm thinking you won't know for sure if it's your rings, scope, bore alignment with the breech or wandering fps until you get the chrony. Once you can test for a consistent shot string then look at the other parts.
If it's just your windage(left to right) likely your scope axis is off compared to your bore axis. Vertical stringing is usually variations if speed, but not always. Well, good luck with your rifle, the R10 is a sweet gun when properly set up.
