alright bowhunting gurus, i need you assistance once again. i tightened down every screw my fossil bow has, and did some more target shooting. at 10, 15, 20, and 25 yards i am right on, but at 30, 35, and 40 yards i am shooting 10 inches to a foot left. what could be causing this? when i put the new sight on, if i was going to be off at longer range, i would be off at a shorter range. could i maybe just be off a little bit, and it's not going to show at close range? i wanted to ask yall before i went messing with something else on my bow. my bow is a bear whitetail, the arrows are carbon wolverines and beman hawk carbons. i get the same result with both brands. i am using 2" blazer fletchings, and 125 grain target points. the bow is set at 50 pounds, if all that matters. and the sight is a truglo 3 pin sight, rest is a whisker biscuit. thanks!
