AR increases the number of adult buck that survive tthe first few days of buck seaon ,only to be harvested as anterless deer later in the season.
Very rare. Most bucks shed around the beginning of Feb. I have routinely seen bucks with racks in early March. Deer hunting in PA ends the middle of January. The number of bucks that shed in time to be taken as antlerless would be even less significant than the occasional forkie taken by a junior hunter.
