If sound travels at 1,096 feet per second, and the bullet at 2,700 FPS, he never heard the gun go off. I myself have heard bullets going thru the trees, and then later I hear the bang.
One time when fishing about 1/4 to 1/2 mile off shore there was a roofer working on a house, and every time he hit the nail the sound came later as he was picking up the hammer.
