I just built an AR-10, did some load development this weekend. Very happy with the results, 1/2 inch groups @ 100. Couldn't be more impressed. I just have a little bit of a problem. I shot in a competition yesterday, 350 yards, 5 stages of 5 rounds, 25 rounds total. 4 out of the 5 stages, my first shot was a flyer at 11 o'clock, about 8 inches high and 8 inches to the left. The rest of my shots grouped within 3 inches or so at center mass. Basically I had 21 rounds center mass, and 4 rounds at 11 0'clock.
Am I seeing the typical shooter error here?
