Never had a deer jump or move out of the way of a bullet. 3000 fps is almost 3 times faster than the speed of sound. I never had one resond to the flash ether. But I did have one jump out of the way of an arrow. I had a doe looking at me while I had the bow drawed back. Could not hold it any longer so I let it go. It was about 30 yard shot. She was quick enough to move out of the way of the arrow
. The hardest thing to shoot with a bow is a squirrel! The best way to get a squirrel is when it is not looking at you and you may have a chance. I shot at a squirrel one time while he was pointed away from me at 10 yards. When he heard the sound of the bow he spun around and cought the arrow in the chest. They are that fast!
