Like Rob, when I used to shoot 3d constantly and every day, I had all the confidence in the world with long shots. I could consistently hold 3-4" groups at 70 yards. That' s what I practiced at. Now that I don' t have the opportunity to do that, I try to limit my shots to 30-35 yards on deer. I can also tell you my confidence level was wayyyyy higher when I used to shoot like that. I could guess within a yard or two out to about 50 yards. Now I catch myself occasionally second guessing myself on yardages. That' s why I bought a laser rangefinder.
