Thread: Difference between ballistic chart and real word results

This all goes to show that theory is pretty good, but not infallible. There are far too many variables to take into account (wind, temperature, humidity, altitude, barrel manufacturing tolerances, bore wear, case neck tension, case manufacture tolerances, chamber dimensions, etc.) that make it impossible for theory to be exact, just near enough. The exact results can only be ascertained by actual shooting, bearing in mind that there are even more variables to consider to achieve consistent results. Top-level target shooters only seek to minimise the variables on any given day as they realise that it is impossible to eliminate them.
