Thats a great point Paul, but not really the original point...
Yes, I was aware that the wind was going to spoil my shooting and decided to give it a try anyway.
But - at the end of the day (while it was still windy) I noticed that aiming by using pressure on the pistol grip only I greatly reduced my group size.
That's what I was really getting at. And it turns out that others have noticed the same thing with the same model.
I'm just trying to learn more about that.
