I dont try and adjust for wind on my first shot unless I'm convinced its steady and from a known direction. Wind always changes direction in the mountains where I shoot. Making a first round hit on a windy day is as much luck as skill. What the wind is doing at the firing line is never the same as 1000 yds. I also seldom shoot with a partner but my guns are heavy enough and of small enough caliber that I can spot hits.

And like I said, you always know substention value if you keep it with your drop chart. So shoot it on whatever power you want, just reference it before you dial...
