I would also suggest spinning the arrows as posted above.
A/C/C's can bend.

a question about a dropzone rest
i bought a dropzone about 4 weeks ago and it was shooting good till now it is very unconsistant i was shooting 6 a/c/c's arrows at 50 yards and 3 went into a three hit the center of the target and the other 3 were about 5-8 inches from the other three. when i shot the 3 arrows that did not group the rest made a diffrent noise than normal. i can't figure out whats wrong it shoot well sometimes and somtimes it just plain sucks.
