Not trying to thread-crap but let's not forget a hiker dressed in black was misidentified, shot and killed by a hunter in skagit a few years ago this way. If memory serves the range was reported as like 140 yards. One life lost and many lives destroyed including the 14 year old hunter, and the hikers young kids.
Using your scope attached to your rifle to look around and identify game is not acceptable.
It is a nice buck.
