Buddy one good thing about this situation yougot yourself into is that others may learn from it as well.

The reason most of the long time crossbow hunters limit their shots at deer to under 40 yards (most are actually shorter than 40) is not that you can't be successful at the greater yardage, but because you might come onto this situation every once in a while. A 75 % success at the greater distances means you can potentually wound every forth deer. The deer does not even have to hear the bow going off, the arrow makes alot of noise durring flight as well as the deer might just move on it's own in normal movement.

Lets all hope we all learn from this and you get another crack at this buck.
