6.5 PRC .5moa at 100 to 4 at 200?

My experience dealing with mirage has been different. Mirage doesn't affect POI, it effects my ability to see a stationary target. (POA) Once the mirage gets to the point where the bullseye appears to be dancing all over the backboard, I turn the magnification down. Reducing the magnification minimizes the amount that the bullseye appears to be moving.

I've had very good results with reducing the magnification and maintaining a better hold when the mirage makes life difficult. Mirage is one of the reasons that I shoot at 8am, which is when our firing line opens. Even on a hot day, we'll get a few hours to shoot before the mirage is problematic.

Not POI (Point of Impact), I stated POA (Point of Aim).

You are correct that mirage does not affect POI. but it absolutely can affect POA.

Measure your twist rate. Parallax from 100 to 200 wont do that bad.

I'd like to see patterns on 100 and 200 yd targets of OP.
