ORIGINAL: the bees knees

Tight groups are fine and dandy for fancy shootin matches, but a deer wont know if you hit 1.1654" off your "true" aiming point...
They will know however if you cut up their lungs or heart.
Groups are for practice anyway, you "Rarely" get a deer to stand perfectly still while you punch 4 arrows in a 2" circle at any yardage. If you can consistently hit a Vital area size target, nothing else matters.
