Harry, I like the challenge of 1000 yard shooting and attended the Long Range Firing School at Camp Perry twice when Middleton Tompkins was holding it and the Marine Scout Snipers were not deployed and were able to be our volunteer line coaches. One of the things Mid said was that he didn't feel there was any value to having sight adjustments finer than 1/2 moa at 1000 yards. The wind changed too fast to fuss with finer adjustments, so you just learned to hold off slightly if you saw a sign that you needed to allow for a 1/4 moa difference or so. Minute of groundhog just doesn't happen out there, even if the mirage would let you make one out through a scope, much less at a mile. The imagination is a mighty thing.
