When in doubt.... strip a couple shafts and bare shaft test them... it may be as simple as adjusting your strike thickness.....
Different bows are going to test differently bro. I have a new set up that i've been playing with that is only 45# @30" & I've had good luck with 3555's shooting well out of other bows of this draw weight. So i grabbed a few fletched arrows and shot them.....It looked like i was getting good arrow flight, but.... i was getting too many unexplained fliers.... When i came off the string perfect they were dead on, but couldn't explain the fliers at all. So i went back in and got some bare shafts the same length and tip weight, and the dad burn things were flying sideways! WAY too weak.... I ended up having to go up to 5575's on this rig.... I'd check it out with bare shafts bro...
