Andy,

What you are describing sounds a lot like Jim Higginbottom's 5-5-5 marksmanship drill. 5 shots, 5 yards, 5" square target. He specifies low ready start you fire as fast as you can keeping all five shots in the square. You add ten seconds to your time for each hit outside the square. The goal is to do it in 3 seconds or less.

The reason for low ready Jim says you are already way behind the curve if your gun is still in it's holster when the fight starts.
