I shoot the 100 grain mag tricks. I shot my first ones yesterday and each shot sounded like wind was catching them and making a hissing sound to the target. They flew perfect, but the hissing threw me off. I have them screwed on tight and all blades are in. What could the problem be. Is their a certain way to line the blades witht he fletchings. I shot my tightpoints and no sound. Anyone have this problem with the 4-blades...
