LOL hawgz...well the speed of sound is 1100fps and since even a REALLY FAST bow only clocks in around 300fps dont you think it stands to reason that the SOUND will get to the deer 4 times faster than the ARROW?

I once saw a video where they studied string jumping...dont quote me on this becuz my memory aint what it used to be...I think it may have been in Primos' Truth series. Shooting 300fps at less than 18 yards even an alert deer has a hard time jumping the string. At distances of 18 yards or more deer have quick enuff reaction times to jump even the fastest bow.
