I recently put together some goldtip series 22 pro shafts. These were going to be shot from a ProElite. I decided to test them in the hooter shooter unfletched. I put the Goldtip Pin Nock bushings in them and installed the pin nocks. At 20 yards from the hooter shooter. The all hit the same hole. This is unfletched. If you have access to one of these machines try this some time with carbons. If they are not good ones, you will see horrible groups. These arrows are not setup with 2.25 quikspins and are flying really good.
