Ok. Did you shoot as it came from the factory? I don't own an X3 but from what I read from the owner's manual, it comes from the factory with six shims. Neutral, or #2 is what should be on it now. If the pattern is ok for elevation, and you don't want to change or adjust that, then to bring the pattern to the right, you'd want to replace the shim that is on it with Shim 2R2L. This will keep the elevation the same as the neutral #2, but will adjust the cast on or cast off approximately 1/8". For right-handed shooters, install this shim between the receiver and the stock with the R
facing the end of the buttstock, so its thicker side is on the left side. This casts the stock slightly to the right, away from the face of a right handed shooter. If you turn
the shim around so the L is facing the end of the buttstock, and it will cast the stock to the left. Pages 23 and 24 of the manual explain how to change the shims. Good luck!
