This is my deer rifle so it only gets out of the safe when I get drawn for deer. But I noticed that last two years when I go to range to make sure everything is good before I head out I have to re-zero scope. This year off several inches at 100 yards. I live in AZ (very minimal humidity) and guns are kept in safe in AC house (even less humidity). I zeroed it last year when went hunting and it has sat in safe since then. That is why I am thinking that it is the optics. I should have new scope in 3-5 business days then I will mount it and find out.
Thanks all for the recommendations
