First off,centershot is way more important than bulletholes for good groups but bullet holes do become fairly important when considering broadhead flight at speeds and penetration.



Your problem looks to be an arrow that is underspined.Second possibility is torque.Try backing your poundage down to 60#'s and see if the bow will bullethole with centershot set.If it does you have a choice between shooting at 60#'s or buying some 340's and going back to 65#'s.

If this doesn't fix it then torque is most likely the issue and you need to try and correct it.It isn't absolutely a neccesity to eliminate torque to shoot well but tuning is easier.


I am in agreement with the others on group tuning but in my case,I usually get bulletholes with my setups when I get the bow and arrow combo right and after group tuning.
