perfect height but all over the place right and left.

I just put a Whisker Biscuit on my bow and it is shooting bullet holes at 3-5 yards.

I shoot fingers and xx78's 2213 27' 60# draw High Country Ultra Pro Series Solo (Matthews) cam.
One shot is right three inches, the next is left four!

Season opens in a few weeks and I am about to have a fit!

Anyone have a clue to this problem?

The pro shop is not an option as there is only one in this area and when they get stumped they call ME!
