I agree with kansaswiderack, there to many uncontrolable variables that can be magnified with a long shot. I personally will not shoot past 30 yds when in the field. I am a very capable shot out to about 60 yards at the range, but there are just too many things that can go wrong. Like the deer taking a step or that little twig you can't see but that will deflect your arrow enough for a bad shot.
