I have a 1.5-6x42 with elevation and windage turrets - it tracks properly per a box test and routinely gets cranked up to ~11 mils and returns back to zero without problems.

My only complaint is that the knob hash marks stop at 6.5 mils (or 7 mils?) and then it has 3 or 4 clicks that are unlabeled...so a full revolution is 6.8 mils (or 7.3 mils?), which isn't an easy number to work with on the fly. [I would check the specifics of the turret but the rifle is currently off at the gunsmith for a new barrel.]
