#94 - Using Mirage to Read Wind
00:48:50 | Bryan and Francis discuss some of the effects they see around making better shots in one of the toughest conditions shooters face: mirage. From strategies to deal with mirage to some of the effects on sight picture, the pair go deep dive into shooting in high mirage conditions.
Thank you for the superb podcast on mirage. Now I can predict when it will occur and use it to my advantage rather than be ruled by it.
It still takes some trial and error to determine how much affect it’s having in any scenario, but just knowing it’s a potential issue is good for diagnostics.

It sounds like you both have experienced vertical mirage effects from .25 – 1.25 MOA at 1000 yds. Would the MOA magnitude be the same from 100 yds to 1000 yds? This concept also implies that the only way to remove this effect (rain, sun & distance to ground) would be to have a machine rest or very stable bench rest and not re-aim between shots. Is this how the benchrest shooters make such small groups?
Good questions. I think the image shift occurs in relation to where the air density gradient is. For example, if you’re looking thru a gradient at 600 yards, but your target is at 1200, you may see no offset up until 600, then see a fixed MOA shift beyond that. I’m speculating here on what makes sense because this is still a new area of research for us.
Take care,
