First thing I ever shot with an arrow was a Jake at 30 with a 405 fps bolt and an enormous mech ( 4 inches I think, swat). Blood trail for like 175 yards but we never did find it. Yup, turkey blood trail. Sucked, but we all know it's going to happen. My point is really that things can and will go wrong with a crossbow too. I don't think anyone here would take sloppy shots or anything, just saying.
Edit: let me take the heat on a less than awesome shot, I'm not trying to make excuses for me either
