   Maybe old news you've already heard...   
      
   Hornady did some research on their tips, found that a flat meplat works   
   better for long range.   
      
   ===   
   The approach decreases dispersion at long range by optimizing bullet   
   tip shape to provide excellent overall drag and unrivaled   
   bullet-to-bullet consistency. Specifically, the meplat must be flat—not   
   pointed—and the diameter of the flat meplat is a specific ratio to the   
   bullet diameter. The new technology decreases the drag variation from   
   shot to shot, resulting in less dispersion at long range...
