Thinking that my arrow weight may be a little on the light side for hunting but dont know if I am figuring it right. I am using Easton Epic C2 400 carbon arrows cut 28.5 inches, 100 grain fixed broadheads/ field points. Eastons web site says they weigh 8.17 grains per inch. My bow is a Hoyt Ultrasport and my draw weight is 60 lbs. Any help/info would be appreciated.
