well i like my alumiunms but they are heavy (479) grains. so i bought some beman ics black carbon hunters arrows cut to 27.5 inch. iam shooting 71# draw and according to bow jackson hunting page they weigth 411 grians i like to shoot 6 grian per pound draw weight. will these arrows be alright for 1 3/4" expandable broadheads and still get real good penatration.. iam shoot bowtech might mite 29 inch draw and 71#
If you bow is tuned and the arrow is flying properly 71lb should be plenty of umph to get good penetration. Right now you're at about 5.78gpi.Thats retty close to 6gpi
