I am also getting this mark on the wrap, about 7" or so from the knock throat. I did the Adock tuning with 3 bare shafts, 3 fletched and got them all hitting in the same area(moving my nock). I put a broad head on the arrow and noticed at close range, the arrows seem to be kicking. I went to the paper and was getting a 5" diagonal tear. My nocking point was off my square, which stops at 5/8". Adding 125grs to the front, along with bringing my single nock down to 5/8" got me perfect holes in the paper. Out shooting in the yard after the paper tune, Im seeing a down range kick in the arrows. After reading this thread, my nocks might be a bit loose, and I will try a double nock set. My nocks arent filed, so I might have to try to heat them in warm water and pinch em a bit?
thanks for the tips!
