I've just picked up a 3200 10x40 for my new .223. The instructions that came with the scope in the box do not mention the target turrets I have and how to adjust them. If I 0 my scope to 300yds the elevation turret will likely end up between two of the 10moa hash mark scale. Is there a way to reset the height of the turret so that my 0 on the turret will once again line up exactly with one of the 10 moa hash marks?
