one end is dead center in the marks and the other is of to the side a little but both are between the marks.. i shot it through paper today. i got bullet holes. i powder tuned it no fletching contact. i shot it with some diffrent arrows.. gold tip 3555s,carbon express terminator hunter 4560s,easton 2117,and easton 2315 everyone had the same point of impact side to side. i also shot with my normal arrows and payed real close attention to the bubble and my bow is level when i shoot. and i am shooting open handed and with how small the grip is on this bow there is no way i am torking it.. so i dont know what it is.
