Hi guys, thanks for all the replies and info, my bow setup is a darton vapor, draw length is 29 and i'am shooting 63 pounds, through paper i shoot perfect bullet holes and i can keep 3 inch groups out to 40 yards, this only started happening when i went to carbon arrows fletched with feathers, i took a few arrows and fletched them with vanes to lower my foc and it seemed to help some, my aluminum arrows are 10.2 foc and seem to fly alot better and have less drop off than the carbon arrows, and the bow is shooting 267 through a chronograph.thanks again for all the replies.
