<span style="text-decoration: underline">Equipment</span>: Nightforce base, ultralight rings, 5.5-22 NXS on R700 .308
I just came back from the range - I was punching paper at 100m just checking my zero and also working on trigger technique - anyway, it was going fine when all of a sudden I was all over paper - no significant wind, no particular shooting errors that could cause massive scatter... I started a fresh target (above) aiming ONLY at the far left square..
<span style="font-weight: bold">I did a dry fire or two with the crosshairs on target and the reticle was jumping everywhere!</span> I jiggled the scope/mounts and it was obvious the base was loose and was shifting around.
Now, this happened once before very recently: I got the rifle back from the gun smith and I just figured the smith loosened the base when he took the barrel off to turn it for a brake. I torqued the base back down at the specified 15 inch/lbs using a torque wrench but clearly the same issue has popped up again.
So..
Has this ever happened to anyone and(/or if not) what would you recommend to remedy this problem? Am I missing something? It has not come loose like this before going to the smith which is weird.
Some guys at the range said either just torque the screws down harder or use a locktight glue or whatever to secure the screws. I'm hesitant to overtorque the screws from the prescribed 15 inch/lbs or permanently lock the screws with glue but this loose rail stuff has to be fixed.
Feel free to voice what you think I should do.
