Are your arrows tuned? What I mean is, when you screw on your broadheads, spin the arrow. Does the BH wobble? If so, you'll need to do some work there.
Also, I noticed you are shooting 500's @ 28"....At what poundage?
Very good point,the broadheads must spin true to fly true.
Broadhead flight is why one should never use cheap carbons and should also use helical feathers IMO.
