Normally, I’d tell you the only real challenge with long-range shooting is the wind, that we have elevation figured out, thanks to the sophisticated ballistic calculators. But at 2,000 yards, that doesn’t hold true. Since muzzle velocity will vary from shot to shot, so will the vertical portion of the bullet’s trajectory. It isn’t usual with good factory ammo (or handloads, for that matter) to have a 30 fps spread in MV over 10 shots. At 1,000 yards, that hardly matters. A shift in MV of 10 fps, for instance, translates to just an inch or two difference in vertical with the 300 PRC. At 2,000 yards, it is a different story: That same 10 fps shift changes the vertical impact by 14 inches or more.
