Leupold Vari x III --- Tracking problem
I just got this scope and it was used , and i put on a kenton knob. Im starting to think im having some tracking ussues . i sighhted in my 200 yard right on,,, then rotated shot from some different distances., when i came back to 200 and rotated my knob to the 200 mark.. it shot about 2 inches low, my velositys are with in 20 fps, my scope didnt move.. what could be causing this? has anyone else had this problem and what can i do to fix it., im taking this scope on a hunt in 2 weeks and im very frustrated, I didnt try dialing past my yardage yet, then back. i heard this helps but i dont know why?? any advice wouldbe great!
