Forgive me for speaking out of turn. I have shot at 1k and am by no means even a fair judge of wind, but the "old timers" I have spoken with at the range don't like the wind behind them. I guess if the wind is one side of your face or the other, even out to 1k, you can tell when to shoot and where to hold. But if it's blowing from behind, they tell me you don't know what it's going to do. This is in prone 1k shooting. I would guess BR is a little different.
With that high of BC and the Velocity your running it, a 10 mile per hour tail wind will only move you 1" to 2" if that.
Not a major concern if the wind stays constant and you had a spotter round or sighter period to watch what happens to the bullet.
That's only one click from a 1/8th MOA scope or 1 1/4" impact change at 1000 yards.
Not really that much to worry about if your Longrange hunting at 1000 yards.
