My arrows are cork screwing at least 7 out of 10 or more shots.  My arrows are Arrow Dynamic Trad Lites 30".
  My bow is a DAS Dalaa with Carbon Max Limbs (Med) 50#.  Shooting from a rest with plunger.  Draw length is 29"

   I have only been shooting this bow for a few weeks and just can't seem get the arrows flying good.  I can get them to group good but, the cork screwing will not stop.  Anyone have any suggestions?

sounds like the spine and nocking point is off.

Have you bare shaft tuned?

Had the same thing happen with AD Trads when nocking point was too low.
