I have a leupold 6x18 vari-x II scope that I have mounted on a new coyote rifle. where I hunt, it is common to take shots from 250 to 350 yards. I would like to use the scope adjustments to compensate for bullet drop after geting the range on my targets with a laser rangefinder. Has anyone tried the stoney Point target knobs for scope adjustments. I would only need to move the adjusments 15 to 25 clicks at the most and the back to 0.
