Mighty nice buck there.
I have shot pretty late, borderline shooting time, and everytime I have connected.
Once, I let fly at 30 yards when the buck was dead broadside. I could not see the arrow, but heard the telltale thawack of an arrow hitting the shoulder. He only ran 30 yards. When I gutted him, I found the broadhead had actually stopped in the heart, and as he ran the broadhead just cut the living daylights out of it.
If you can place the pin, take the shot, that is how I look at it.
