Re: target knobs like \"best of the west\"
Go to the Leupold website, and click on the Custom Shop. I sent them my Vari-X III in 4.5X14X40, and had them install a target turret, and then a custom Bbullet Drop Compensator for the ballistics of my .308. It works great. Once you have your baseline zero (I only have access to a 100 yard range), you set the 100 yard index line on 100 and tighten the Allen head set screw. You're now good to go out to 1000 yards, assuming you gave Leupold the correct ballistic info.
