I have my bow set at 55lbs and my arrows are for lb range 60-70. I have been shooting at my 3D target and when I shoot and watch my arrow flight the tale of my arrow flies crooked and like wobbles but it hits the target straight.....the arrows arnt hitting the target crooked. I was wondering what would be making my arrows fly like this. I am shooting 85 grain field tips and plan on shooting 85 grain montecs for season. I dont know if the tips arnt heavy enough, if the arrows arnt small enough lb range for my bow, or what. Any help appreciated THANKS!
