Reading updraft/downdrafts

[thelongranger]

Looking for any material or articles on reading updraft and downdrafts for elr shooting. There's not much out there online.

I'm shooting across a narrow, steep canyon at 400m bang on for the first target and the second target is at 417m.

I occasionally get unexpected flyers either above or below the target. I am aware that it can be ammo related and take that into consideration.

This tends to occur if I don't shoot with the wind direction or intensity being absolutely the same around me, and from what I judge the wind is doing by watching the trees , brush and grass around the target. Between the two, I try to interpolate and make a swag about what the wind is doing. I need to be better.

Have you done the math on the elevation variable at 400m that your ammo's velocity extreme spread will cause?

 

[thelongranger]

Yup.

The boyz were playing at 500 meters yesterday with a .22 CZ after the centerfire session.
The big strike is a random hit from a 308.
MANY minutes up and POUI up on the berm to boot- they ran out of turret after 300! LOL
