A friend and I were shooting at 1240 yards one day and backed off the target 500 yards so we were at about a mile with my .308. (1740 yds. to be exact) Very little wind or I don't think we'd have been able to do it. Like someone else here mentioned, it can be hard to see your misses in the dirt at that range. With 168 grain amax at 7700 ft. elevation on a warm day it was easier than I thought. We ran out of elevation adjustment on the scope and were looking at the target through the bottom of the vertical stadia on the reticle, 25 mils up alltogether. We each hit a 10'' balloon (taped to cardboard) on the 3rd shot at that range. Quite the experience, just looking to perfect it. I've since switched my 20 moa base for a 30. Still have alot to learn about wind.
