So when you lung shoot a deer and it runs off, do you assume you hit it solidly, and just watch it run?
Mostly yes. A good bunch of them never make more than a few steps, most not more than 30 yds. When hunting from a stand (or a perch ast Steelhead put it), and shooting at a deer 30 yds away with a rest I generally feel pretty comfortable with my shots.
If I am not confidant of the shot.. then I keep shooting until their down or I can't see them anymore.
