I bought the T3 lite in 338 and know I've blown out a piece of the front scope mount twice. The back mount is also shifting on me so I can't eject my shell and it's also obviously moving my scope. It was put on both times by a gunsmith, so I believe they should have been tight enough. Anyone have this same problem with the Tikka factory mounts on a 338? What would you recommend? I'm going to Alaska in August and time is becoming an issue.
