I'll give you two examples from this past season. The first buck, I aimed at the top of his heart at 22 yards...at the shot he ducked and turned making the hit high and forward, if you guys remember that thread....

What you don't know is later in the week I missed a second huge 8 point becuase I aimed low for compensation...will never do it again. I had a beautiful 8 scamper buy..would have been my largest, at 42 yards....I grunted and stopped him and he hooked a tree aggressively...he then looked my way and not seeing any other deer he tucked his tail and started back the way he came...he stopped with his head behind a tree, I ranged him, 42 yards, tucked my 40 under his heart anticipating his duck/drop and I watched my arrow go just under his heart and miss...he never moved, never heard the bow dispite his nervous condition...had I aimed at the top of the heart...perfect shot...I'll never compensate again.
