I realize this is a couple year old thread but I’m having a similar grouping issue with a new T3X in 7MM-08. Took the stock off and noticed I had the same wear marks as this. Did you ever address the rings in the stock? Were you able to get your groups tightened up? Thanks!I pulled it apart tonight. The recoil lug looks fine. However there’s a shiny spot on each side of the barrel where the stock is contacting it. The finish is worn from it rubbing under recoil.
Anyone think this could be the issue?
