I have a 2010 Fire Cat 29" draw weight @61 lbs and I have been experiencing nocks falling out in flight. This has happened with both Gold tip 5575 expedition hunters and 5575 XT hunters. I'm not opposed to gluing the nocks in but that seems to be simply masking the problem. The nocks don't appear loose and today I was shooting XThunters for the first time . On the last 3 D target # 15 the nock came out on the way to the tatrget. I had hoped switching to the XT hunters would correct the problem. Any thoughts would be appreciated.
