My two cents: Bullets have a rotational motion, which causes a bullet to "bend." Unfortunately for Hollywood, this bending does not occur at close distances. At ranges approaching and exceeding one mile, bullets will bend slightly. They bend enough that you cannot accurately plot them within a certain radius (a matter of inches). But you never hear about 2-mile shots. Aside from having to arc your shot severely, the parabolic rotation of the bullet becomes so much that the grouping radius is now a matter of feet. In other words, EXTREME long-shots are near-impossible due to the "bending" of a bullet. Now, for pistols, the limitations of the weapon (short barrel, less rifling, bullet dynamics) make it so that the accuracy and effective range come into question long before parabolic rotation ever does.
