using target knobs?
I was shooting a few days ago,and adjusted the elevation knob to hit at longer ranges. When I returned the elevation knob to the zero mark,the gun was shooting low at 100yds (the orginal zero distance). Should you turn the knob past the zero mark,then back to zero? The Scope is a Sightron SIII 6.5X24X42 Mil Dot. It's supposed to have the "Exact Trac" feature. It didn't however, shift the windage, it just shot lower than orginally set. Any advice will be appreciated. Ron
