I voted for the 6 inch group as a worst case scenario(i can do it on my worst day).Shooting at a target on a nice calm day with all the time in the world to hold and release is no problem but put a big buck in place of that target when he's on the move with his nose to the ground and i have to THINK i run in to a little trouble with my heart rate and adrenaline--that's what makes it the greatest way to hunt deer in my mind.Give me the same deer during rifle season and i hardly get excited about it.
