I am working on tuning a Mathew’s Switchback after a string change. I have been working on removing a nock left bare shaft. I am right handed. I’ve got my bare shaft grouping with my field points, but my broadheads are impacting about a foot right. In the photos the broadhead hit is indicated by the blue arrow. I know I still have a very slight nock left but I’m not if that is enough to cause the broadhead to be so far off. It’s been a long day of shooting, hence the open 20 yard group!
