My arrows are hitting target at angle. They are striking target and knock is 2 to 3 inches to left from center. I also noticed it gets worse with repeated shots. I shoot into a layered foam target. They are carbon express terminators 4560. I am shooting 55# recurve with 29" arrows. I use 5 inch helical fletch true flight feathers. I also use 100 grain field tips and broadheads. I was considering going with cedar.
