RE: Bare shaft tuning results...(8in. right = ?)
You also need to make sure that the arrow perfectly bisects the berger hole and your nock is set so the arrow is dead level. This should give you flat nock travel. I had a bare shaft that was hitting 8" left and this fixed the problem for me....I got this information straight from the Mathews techs.
Despite popular belief.....left to right problems can also be attributed to nock height.
