Do you mean a situation where the mirage is so heavy the image you see of the bullseye is displaced from its actual position? Or how to infer wind speed and direction from mirage?

image you see of the bullseye is displaced from its actual position? ...that is exactly what I am dealing with at the moment

Is this with iron sights or scope and at what distance?

I would say a frame hold if it's that bad on the target black

The phenomenon that milprileb and NMC_EXP are referring to is due to refraction of the light making the image appear to be offset from its actual position. It takes an experienced eye to properly identify and correct for this phenomenon. It really isn't much of an issue at close ranges but is much more significant as the range increases. This article is very good: http://southtexasshooting.org/multim...xt/mirage.html

Pretty good article - thanks.

I agree with the author that high humidity makes the mirage worse i.e. "thicker".

Rifle scopes magnify all of the mirage between you and the target. The higher the mag, the more distortion there is.

I used to shoot a 100 yd smallbore prone league in the midwest. The firing point and targets were both low so your line of sight was very close to gound level where the mirage was thickest. On high humidity 90+ degree days it was easy to loose a lot of points due to target image displacement.

First time that happened to me it was so bad I something was wrong with the rifle. I got out position and checked to verify my sights and guard screws were tight.

800 and 1000 yards is the distance.
