[QUOTE="mattj, post: 254957, member: 8758"] I'm pretty certain that is not correct (and maybe a true optics guru can jump in here and explain it better than I can)... but when you sight in the scope (and use proper parallax adjustment) on the horizontal axis, you are making an angular adjustment to the horizontal sight plane so that it is parallel to the horizontal barrel plane. By dialing the scope in you ARE syncronizing the sight and shooting planes. As long as you can dial the scope enough to get the reticle "sighted in" (and still have the adjustment range you need to dial windage), the "plumbness" to the bore axis really doesn't matter. Now what you can't correct for is horizontal offset -- but its effect is so miniscule compared to the angular factors that it becomes insignificant. -Matt [/QUOTE]
