On the military ch. a US sniper was know for shooting bad guys running across street at 500-600 yrds. He also had alot of practice, Years later they tracked sniper down and recreated the shot, it was cold winter day w/15 mph cross wind, range 600, target moving as fast as human run, both dirrections. Results shot 1, miss, shot 2 10 ring, shot 3 think was 8 ring, torso hit anyway. I COULD tell his old arm coach was impressed, sai that guy is a shooter. In the Shooters Bible, Jack O' Connor, practiced on running jack rabbits on a regular basis, and shot running deer out to 300 on a regular basis. My neighbor down the street son shot moving target pellet gun in our local club, I USED TO WATCH HIM, when I was at pistol club, he woud shot 10 rings moving, but you use a aiming point on paper for the lead, offhand, he almost made olyimpic team. Even with this said I CALL bs on the guy
