Accurate long range shooting is impossible if one does not adjust for temperature with precision. In this video, Rex shows how important adjusting for ambient air temperature and for ammunition temperature really is. Want to hit drop that mule deer buck at 1000 meters? Then you will have to watch this video. Rex exposes the shortcomings of the US army Sniper Field Manual FM 23-10 on this issue. Using the .308 WIn with 168 grain BTHP MatchKings as a reference, Rex illustrates what happens with a typical long range shot when temperature is ignored. All the music, animations, and photography in this video were created by TiborasaurusRex, and unsigned artist.
