I got a doe a few years ago lasered at 63 yards but I wont do it again. it was a stalking situation and that was the absolute closest I could get provided the cover I had available. Very light wind coming directly towards me, she was in an open grassy area with her head down munching, perfect broadside shot. Still she heard it and reacted more than I anticipated, by the time the arrow arrived at its destination she had turned away and the arrow entered her rear leg on the left side and stuck into her shoulderblade on the right side, made a big mess of her insides and she didnt go far, maybe 60 yards, but it was a lot messier cleaning job than Im used to with my bow, green stinky shit everwhere and she broke my arrow when she was running also which I wasnt happy about. Farthest I will go now is 40 yards and prefer 20.
