Yes I have had scoped do the same thing cant explain why that,s when i got it back to where it should be I started bore sighting after it was right and keeping a record of position and believe it if i don,t use a particular rifle for some time some will move not all .
Did you check the focus control for parallax?
Yes mate I did give it a good oil before putting away, but I dry patched it all out before firing the 200m shots, then put it away again for a week as is.
What I don't understand is the massive difference in 7 days sitting untouched. I treat it like it's made from egg shells, the biggest impact it ever gets is the tiny recoil from the mild .223 loads I use.
I also spent the time when I first installed it, testing to generate range notes for 100, 200 and 300m, so I just have to consult them to know what to dial up for each range and that has served me well until now. All other variables removed, Occum's Razor has it looking like some internal drama or turret problem.
As the turrets are easily swapped I'm hoping that is the culprit.

Yes mate, I checked them all after the 200m last week were unusual. All tight, none apparently broken.
I'm going to pull everything apart today and put it back together from scratch, rings, rails, scope out of rings. Can't make it any worse.
What really put the wind up me was dialing six quarter inch clicks up and seeing it impact 18 inches low.
