I just got an SWFA SS 16x fixed mil/mil scope. My question is this. I got the scope mounted and rough bore sighted it with my laser bore sighter. Had to run it up a few clicks to zero the dot and reticle and am headed for the range tomorrow. These things come with no directions so I assume that once I get it zeroed on paper I just loosen and then re-tighten the turret screws to my zero mark?
