I don't know if 1,000 yds BR is like short range BR, but for our F-Class matches at MCB, Quantico, VA (Open (mechanical rest) and F/TR (bipod)), we sure don't have wind flags all along the route of bullet travel. I can tell you that without flags, neither BR nor F-Class shooters will set records at MCB, Quantico, VA after about 10:00am. The wind always comes up and often the flags at target #1 and target #50 are blowing at each other. You actually need mirage to help with the wind at distances between target and shooter. Wind shoots through the road cutting across the 600 yd line and you have to watch the mirage on the asphalt and tops of the trees at that distance. If you can put rounds down ranage between 0800 and 1000, you've got a chance.
I'm not even sure life would be any better if we did have wind meters every 100 yards or so. They would be so contradictory they may be hard to interpret.
Also, again I'm not sure about 1,000 yd BR, but NO MUZZLE BREAKS in F-Class.
