Yesterday at the out door range I was getting up to an inch of drift due to the swirling and variable wind. I was using a BAS r10 .22 firing JSB Exact Express 14.35grs @ 600ft/s. The grouping was acceptable up to 30 Yards but from there on it was anyone's guess. The wind was also lifting the pellets high from 40 Yards with up to a 2" elevation @ 75 Yards. This was the first time that I experienced the effects of such swirling wind. The met office had predicted gusting of around 20+ miles an hour which I believe was correct. I guess if this happens in a real shooting situation, one might as well pack up and go home as there is no way a sub 12 rifle could cope with this kind of wind. The guys using .177 were also affected but not to the same degree.
