I'm still unconvinced that it is relevant to us in Field Target in the .177 calibre at the typical FT distances.

I am still open to being converted however, and even though I have never seen anything discernible in my own shooting in wind, that is not a definitive proof to me that it is not occurring. It just means I have not observed it, or it is insignificant.

In the field of long range air rifle shooting this may well be significant, and if 100 yard shooting does take off, it will be important to know.

The wind speed was fluctuating between 2 to 6mph. I was using a portable anemometer.
I have from time to time experienced the Magnus Effect a 55 yards but because POI was going the wrong way to conventional thought, I assumed it was some technique error on my part.

As to.177, 16 joule/12ft lb, 100 yard Target Competition.
I think it could be a very interesting.
I think it is the equivalent of 1000 yards with .308/7.62 without the cost.
A bit like F Class for air rifles.
There is nothing impossible to those who will try!
