I have had to hunt with a crossbow for the last 6 to 7 years and have killed probably 20 deer with them. For me, deer do jump the string much worse than a compound due to the noise. But, the magic number for me is around 26 yards. Less than that and the bolt is there before they can react. More than that and I risk a bad hit as the deer will be moving. Thus, I limit myself to 26 yards shots or less. Really pretty simple to figure out with a little experience.
