Whats your first order of business this year, as far as hunting I mean?
Did you ever get your bares impacting with your feathered shafts at 20 or 30 yards? To really fine tune, if you can pull it off, as you get closer to tune, you can shoot them at like 50 yards. That will REALLY tell you whats going on. The Olympians shoot there bares with their fletched at 90 meters....
At that point though, you will get a flyer now and again because of release issues....release has to be about perfect to get good flight at long distances with bare shafts.
