Will a loose nock cause erratic arrow flight? I have a Death wish longbow that had perfect arrow flight. The arrow rest was wearing out so I replaced it. Same size and thickness. Nothing else changed. Now I can't get good arrow flight. I tried thicker and thinner arrow plates. Tried to retune the bow, raised and lowered the brace height and nock, one adjustment at a time. Still arrows wagging left/right, mainly tail kicking left. I'm running out of ideas, so I thought it might be loose nocks. Any help will be appreciated.
