I purchased 2 tikkas last year. 243 and 308 .nice and light easy on my bad shoulders. The 308 stock rings would not hold my scope the scope was walking forward after every shot. I ended up putting a little sticker in front of forward scope ring and you could actually see it moving away after ever shot. Of coarse this happened 1 week before my Colorado trip. cabelas did mount the scope the first time Bushnell legend hd. I also tried a dnz did the same thing. I ended up 2 days before trip putting a thin layer of liquid electrical tape on rings and remounted. It has not moved at all. But in my mind it is still not right. I called Bushnell tech support they said never heard of it. Kind of think that was BS cause u Google it and I am not the first person with problem
