Last nights visit with Mike to his vast Lambing farm, produced a Dog and Vixen, Vixen very heavy so a good result ... After a chat with the farmer, and in between the gusting rain flurries, we did our usual check zero, but as we were unable to gain the ground where we normally set targets due to the very wet conditions, we chose a 150 Yard option very slightly downhill, and across a small stream that runs down a gully, about 30 yards from the targets, When you print an inch and a half left of intended fall of shot when shooting with the wind behind you, it demonstrates the violence of the gusts hitting the gully & rising up leftwards, So when you miss that sitting bib shot consider what that nasty gusting stuff is doing.
