[QUOTE="Litehiker, post: 1680019, member: 54178"] Wild Bill, What do you mean by "setting" a parallax knob? The factory "sets" the parallax knob for infinity and we scope owners live with what the factory has given us, and in a quality scope that is virtually always correct. Yes many [I]parallax/target focus[/I] knobs do have yardage of meter numbers on them and those are almost always "ballpark" numbers and not exact. And many parallax knobs only have dots on them, the manufacturer realizing the numbered knobs always lie a bit. As the OP stated, parallax target focus adjustment is to get the reticle and target [I]in the same focal plane. [/I][U]This means when the parallax knob is set properly you get no "parallax effect" (of the reticle moving around on the target) by moving your head slightly back and forth or up and down when viewing the target.[/U] As I stated earlier, to be sure you are not having a parallax problem (misplaced reticle on the target) [I]keep a perfect circle of shadow around the edge of the scope. [/I]This means you eye is centered. Eric B. [/QUOTE]
