I'm using 1:7" twist but I guess the question is the same for all twist rates.
How much change of point of impact do rifles have for different weight bullets?
Stereotypical info says 1:9" shoots the lighter weight better and 1:7" imparts the needed spin to stabilize the heavier bullets.
What is your POI change when shooting the poorer weight (for your rifle)?
Is it typical? Low and left? High and right? Or?
