I have a hoyt rx1 turbo that I had dialed in, I recently waxed the string. today before shooting I slid my nock point down a hair by slightly working back and forth with pliers to get it to just barely touch the top of my d-loop. my first two shots at 50 where pretty good, but I heard a little noise. my third arrow when shot hit probably 15-20 yards before the target, two more additional arrow followed suite. I check to make sure my drop away was working correctly and it appeared it was( rest cord is served in and impossible to move). not knowing what else to try I worked my nock point back to where I started. after this I was hitting a tad high and to the right at 20 and 30 yards. after a few more shots the string "seemed to settle back in" and I was hitting dead center. I'm happy it is shooting better, but doing want to have a failure like this in the field. anybody have any other ideas what could have happened or what I need to check? thanks
