Help un-confuse me!

OK I am working with a 300WSM and have my load worked up. I entered everything into the LoadBase 3.0 program to get my bullet drops. I printed one version with the 'Linear' information that tells me that at 500 yards with a 200 yard zero, the bullet will drop 34.7" The other way I did it was in the MOA mode. At 500 yards, it is telling me that it will drop 6.6 MOA.

Now I realize that for all intensive purposes that a MOA can be assumed to be 1" at 100 yards, 2" @ 200 yards and so on.

Now this is where I am getting a little confused. The scope I have a Leupold Vari-XII 4-12 AO. It was made around 1997-1998, so it doesn't have the 1/4" clicks. It uses the smooth rotating elevation and windage adjustments. It just says MOA on it, and as far as I can figure is scaled for 1/2 MOA.



So my question is:
To zero the scope in for a 500 yard shot, do I move the elevation about 6.5 marks to correspond the 6.6 MOAs, or do I move it about 35 marks for the 34.7 inches?

    You're going to move it 6.5 moa, not 6.5 marks. Each mark on that scope is a 1/2".

    so right now it is set at the 2.5 mark. Where would it be set at for 6.5 MOA?

    Turn it up to position 9, which is mid-way between the numbered 8 and 10. The individual dashes represent .5moa. 2 dashes = 1 moa

    Are you looking at the windage turret or elevation? Should read "U < 0 > D" shouldn't it? JohnnyK.

    Just a correction: it is "for all intents and purposes."
