My buddy has a z6 2.5-15x56 b t. Model . When he was sighting it in he had to max it out to the right to be on at 100 yds but at 2-300 it still shot to the left 5-7 inches according to my friend!! While we were fiddling with it we discovered that they was only slightly over 2 complete turns of adjustment !! Left to right. Approx 2 1/4 turns!! Is this the norm for this optic or should it be more??? Help. Tribb
