Did you do the paper tuning or some guy at the pro shop?

Did you group tune?

Did you do a walk back tune?

Did you spin check your arrows to see if they had any wobble in them?

Have you checked for string creep?

I for one put no faith in paper tuning and if I do shoot through paper it is only a starting point of the tuning process.

Go to Eastons site and download their tuning guide.
