I want to thank everyone for the responses to this thread. I shot a 200 in an NRA match in Rexburg Idaho a couple of weeks ago. In Rexburg wind is a major factor and the first time I shot at this range I thought this is the worst place on earth for a 1000 yard range. After a few matches, I learned like the wind. With 20 shots per string I thought it would be impossible in Rexburg.
