I'm shooting a Martin Hunter 45# drawing 29.5 Shooting Axis 500 30in 100 grain insert 100 grain field point brace height at 8 1/4 not at 1/5 .
Have tried several arrow and different brace height and nock set.
I get a shelf noise and rug wear on the outside edge, It sounds like the shaft is slapping the shelf.
Any suggestions would be appreciated.
