Well, emphasis on hope for the best should be made in sgtbaker's writeup. While shooting from the hip is an impressive idea (not unlike double shooting with two pistols), the rifles and shotguns out there have sights for a reason -- one should aim by looking through the sights!

Speaking of which, "Shooting from the hip" is a phrase used to describe a person (like a politician) talking impressively and quickly, but not always accurate.
