I have recently got back into archery and just got my wife a bow. the question i got is 3 deg helical shootin through wb could that cause problems with arrow flight. she took my old arrows and had them fletched before she found bow she wanted. she is shooting a bear apprentice 23 dl and 38 dw. the fletches are 1.75 inches long. She can burn the target up at 10 yards but every now and then shoots 4'' to the left think that's cause pulls on the shot. but when she goes out to twenty yards shoots some left and most bout 6'' to the right. so we tried to paper tune it but tear is different every shot. just wondering if the helical could be causing the problem or what Yall think?
