Wind reading is a personal evaluation of what you see on the target. When you are considering what conditions have the most effect on your load then the shooter must fire a shot on the target and receive information back that he or she is reading the condition, there is no particular flag to read or row.
Mirage has a big part in short range shooting and to have your scope focused on the mirage causing you the most effect is challenging for new shooters.
Conditions travel in and out of parameters like a sine wave it is up to the shooter to choose when to shoot and more importantly when to stop. You have to shoot with both eye's open and train your eyes to swap focus at will.
To be able to consistently learn from wind and build skill set up you have to make sure your rifle and set up and your ability to get accurate shots off in whatever time you have identified as your condition stabilises for.
There are two main ways to shoot a condition -
Pick the condition fire 1 or 2 shots evaluate then continue
Run a condition time the condition on your timer if the condition looks consistent for 10- 12 seconds then this is how long you have to fire your string.
Being able to shoot in the wind relies heavily in how you set your rifle up and where you have your gear laid out on the bench for instance. I set my gear up exactly the same every time, string ammo in the holder sighters in the box on the left-hand side, timer on the left at the end of the bench so I can see the time clearly whilst aiming on the stock or firing.
Even the way you crowed the rifle has an impact on your ability to view flags and thus gather condition information.
Benchrest shooting is very very lucky with flags and where you place them is so important.
good shooting to all
