Sighting In Question

[rangerhgm]

I noticed on advantagetactical.com they say that when adjusting for elevation each .002 shim will lower impact approx. 3/8" at 50 yds.

At 25 yds would the change be half as much (3/16") or twice at much (3/4")?

Half the distance, half the change. That's assuming a perfectly flat trajectory.
