That small caliber is really affected by wind, it will be double value if you where sitting next to a 300wsm at1000, but it is very accurate, depending on range, you want to know wind at many locations on way 1000 is far.I shot with a friend today that had to do a 30'' windage and I THOUGHT IT WAS CALM. I f you have room, or a berm or something, set up sighter that you can watch for impact, spotter in a good scope.This will help combat wind , shot first thing in day, calm , and beat the mirage,look for it in scope. We used clay pigeon for siter. easy to see, sheet of osb with butcher paper is good backer for shots. I f conditions good send them quick so wind has least impact on group, have fun.
