I shot a 3 shot group at 2000yards yesterday that only had 11 inches of vertical and made the group size. I had 9.5 min of left windage in the scope. I may be starting to catch on.I shot two. One was a 4 shot and one was a 3 shot. I haven't shot this rifle much at 1000 yards to save barrel. I built this rifle to shoot 2000 yards. I shot at 2000 yards yesterday. One 3 shot group was 17 inches and one was 20 inches. I was very happy. I had the bad verticle at 1800 yards and I think most of it was from the conditions. I was shooting in a 8 0'clock wind of about 3 to 5 mph.
