pulled back to full draw, released, POWWW, gold tip nock broke, that got my attention, luckily no damage to my brand new Bob Lee Ultimate or me. checked everything on the bow out real good, saw no issues so shot another arrow, carbon express that is, after hearing of nock problems on the gold tips and then having one, I might be done with them. never want that to happen again. I have been shooting bows for 37 years and that was my first time I ever had one blow up, and I didnt like it one bit. I always inspect my nocks before I start shooting also, saw no problems with this one, until POWWWW.
