Abiding by the law and he is indeed, at that point, considered an antlerless deer, I would kill him and let the taxi do his magic. I'm sure your game departmant has figured this late season antler shed into their season dates and quota numbers (isn't it about the deer and not the horns from a conservationist's point of view). Would you have shot him if you didn't see his antlers drop and the horn weren't there? The law is the law. Where have youerrored by killing an antlerless deer? What you do after the fact is your business, right? If he was good enough to shoot on day one,isn't hegood enough late in the season? You were given a "factored" in bonus, IMO. Ethically, I do not see any reason why you shouldn't or wouldn't capitalize on it.If I were looking for a "book" deer, I would naturally pass.
