generally, if you shoot at an animal and miss just over their back while shooting instinctively,
it's because you didn't keep focused on a small spot you wanted to hit, and instead you were looking at the entire chest area instead of a small dime size spot on the chest.
I have been there,done that before myself. :eek:
I find stump shooting is the best training method for me to tune-in to picking small spots and keeping my focus.
One other thing, hold your form when the bow goes off and don't 'peek' to see where you hit until after the arrow is in the target/deer!
