For sure! There have been many bucks I've passed due to recognizing them right off the bat. I study them hard. Many of them would have been shot at in that 20 second window opening had I not noticed a certain characteristic in the rack.
Knowing the caliber of deer you have helps you set your personal standard. I passed a very nice 10 pt this year twice. Both times he looked impressive and had I not known what deer he was and never gotten a picture of him, he'd probably be dead. But I already had my mind made up. The last pictures I have of him were very early December. If he makes it to next year, he will be very impressive
