I was looking up scope tracking and on some of the long range power burner forums there were a couple people who repair scopes and they said a majority of the repairs are the internals of the scope when they’ve cranked the scope all the way down to zero their scopes at -20 to -30 moa. THE PROBLEM IS they leave them there and the springs set or break altogether. Which results in crappy tracking as you can imagine. They recommend, and it makes sense, to return the reticle to neutral to store it. Then rotate to zero for the shooting session. FYI
