Hi all.
I have a question concerning the nxs 3.5-15/50 scope.
My shooting partner has one fitted to his tikka 3 stainless light and just recently it has been playing up.
After a couple of shots the zero moves 4inches to the left. Upon re-zeroing he has then gone out and dropped foxes at 150-200 yards.
Then completely misses one next time out and again upon checking the scope is 3-4 inches out to te left.
Now I would expect a drop problem but not a sideways one.
Any experts advise what the problem could be. (not good for a £1000 scope).
He uses factory loads and
