I got a new Black Ice the other day sat it up and went out side to shoot it at 65lb with a 28 3/4 axis 400 with is on the light side, a 85 gr thunderhead and 2 inch Blazer vanes set my pin at 26 yards and broke nocks. putting field and broadhead together in a 4 inch spot out to 30 yards. One pin good for 15 to 30 yards they fly great and makes very little bow noise. Sounds like you have a tunning problem
