The kind I used was pretty popular with centerfire BR shooters, but as I said, it didn't seem to work well for me with airgun BR, esp at fifty yards. Of course it predicted that winds from right will blow you left, and vice-versa, but the quartering head and tailwinds often seemed to give conflicting results in the effects of raising and lowering hits.
I shoot in wind all the time, ad it comes from all different directions. I tried to like the chart I had, but in the end, abandoned it. Like many shooters I see, I tend to just pick one or two flag conditions that I think will be around for awhile and learn where I'm hitting when I see em. Trying to learn a LOT of conditions for the day usually doesn't work ok for me. Most of us prefer a headwind, even a strong one, to a full 90degree crosswind, even a light one.
