The only people who care about the technical aspects of shooting are shooters. If the movie is too technical, attendance will suffer, because the regular folks don't care. Still, some things annoy me. When the hero in "Shooter" shot the soup can with his .408 CheyTac, the muzzle blast would have blown his poor dog right off that rock. It takes time for a bullet to reach a long range target, so when the shot is made from the point of view of the target, the sound of the muzzle blast should follow sometime later than the sound of the bullet impact. Same with explosions, if you see something blow up in the distance, the sound comes later. When the hero makes a successful long range shot, please make it look like he's trying, unlike the Quiggly bucket shot. As for shooting at a mile, if I can zero my rifle to hit 80" high at 100, I'll be close, so provided I account for wind speed, and direction, spin drift, mirage, coriolis, temperature, elevation, humidity, rifle cant, velocity spread, errors in range estimation, and variances in bullet BCs, there's nothing to it!!!!
