Childers.... always check those nocks before you put an arrow on the string. Just stick your thumb nail in the nocks slot and apply a little pressure to each side. A weak or hit nock will instantly reveal itself. I also run my fingers around the outside, especially at the ends of the nock slit checking for hit's or burrs indicating a hit. It can be dangerous to shoot these half busted nocks. It can go off at weird angle endangering others and property or it can become the almost instant dry fire ruining equipment. You find a weak one immediately yank the nock and stick the arrow in your quiver upside downso you don't accidently try to shoot it.
