That has been my experience as well mobow. I live and hunt out west and I'll shoot at 40 yards but don't think the heavy arrows handicap me at that distance. In the past I used a different set up for antelope, if you have ever shot one they are like hitting a piece of tissue paper. I went with light, small diameter carbons and expandable heads. When I was sighting in I found that I really didn't need to move my sight. Shooting at a 4 inch spot both the heavy and light arrows were in the spot. The difference was only a couple of inches. I've since went back to my heavier arrows for all hunting. I shoot around 485 grains. If my yardage is off by 10 yards either way I'll still be in the kill zone.
