[QUOTE="Shawn Carlock, post: 219421, member: 4"] Len the real problem is when you change locations. If I shoot at my local range the pressure will run 27-28, if I go to my hunting area it runs 23-25. If you are shooting BC challenged bullets or extreme distances it makes a big difference. In the end it is one of the many things to add to the compounding errors list. A little off on BAR, a little off in elevation, cosine of .94 instead of .96, then add in some wind components and scratch your head why you missed. [/QUOTE]
