I think the biggest part of it is mind games, but I don't know how to fix it. The other night I stood at 26 yards and put five arrows in a row into the 3 inch circle on my target, then the next round I stood at 30 yards, and I could not hold steady on the target like at 26. When i get to 30, my sight is bigger than the circlce I am aiming at, so maybe thats the problem.
Whatever the problem is, I don't like it. I just take care of the problem by not shooting from 30 yards.
