Hmmm I'm thinking something might be askew (catch the punn?) with ur cones as mine are flying very well indeed. I just have not had the chance to test them against the normal ones with the cones right to the end of the skewer shaft to see if one type shoots better than the other. But I sure like the shaft out the back for pushing them down into the bore consistently. I am liking them.I love it! I have found though that the darts I make with the cone down the shaft so that the end of the skewer sticks out ... do not fly right. But if the cone is right at the end of the skewer I have no problems. Any ideas on that?
