So my friend and i were shooting bow, and he has an '08 firecat, like me, well we were shooting and i didnt realize he forgot to nock an arrow, but by the time i noticed, he had shot, the bow made a very loud nosie, but nothing happened, the limbs did not break, nor the cams. that same day we took it to the local bow shop, and he went over the whole thing for a day, we got a call yesterday saying the bow was completely fine. The dealer said he pulled it back, and no foul noises, but of course he had his machine pull it back. he then shot it ten times without anything wrong. Well that day he called us, we went and picked the bow up, and its shooting perfectly fine, is this normal, or does this happen once in a million?
