So a doe came down the trail and didn't notice you. That part is good. Then you decided to make noise and all that. WHY???? You're on a well used trail. It's the time of year for bucks to be wandering. Just let nature take it's course. No need to go making artificial noises without seeing a deer. That doe passing by was the best thing that could happen. That buck wasn't following your call. And then you put him on alert after he shows(on his own) and you feel a need to grunt at him. He was following the does scent. don't put him on alert at 20 yards... just shoot him.
