RE: Are some bucks impossible to kill????
There was a very good article on this very subject in one of the magazines I read a few months ago. I can't remember which one, but I think it was either Deer & Deer Hunting or Bowhunting World. Anyway, the article stated that after a deer reaches a certain age, usually 5.5 to 6.5 years old, it does not engage in the chasing of does during the rut. It will breed maybe 2-3 does per season and does not fight or chase, mostly because at that age it does not have to. In areas that receive any significant hunting pressure these bucks are almost exclusively nocturnal and are definitely nocturnal during hunting season. So, by this line of thoughta buck that fits this description is theoreticallyimpossible to kill...legally, that is.
BM, the buck you are referring too would be very difficult to hunt and kill, but not impossible. If he moves during daylight hours you can get him. You will most likely have to abandon traditional hunting methods (i.e. treestands, or ground blinds) and employ some more unconventional methods. One might be a pit blind very close to a trail that is used in the brush. Another might be a stalk through the corn (if allowed by the landowner). As Atlas said you would have to wait for the perfect conditions, but I think you could get him. And if you did, what a trophy he would be regardless of size.
