[QUOTE="DavidleeCole, post: 1715044, member: 85306"] Air density has a great effect on bullet drop as the closer to sea level the harder it is for the bullet to push through the air and wind. Adversely the higher up the mountain you go the less dense the air is and its easier for the bullet to push through. With my 300 Whby mag at 500 yards going from 95 degrees at 450 feet elevation and 29.5 inhg my drop is 1.1 mil and going to 50 degrees at 6000 feet and 24.0 inhg my drop is 1.0 mil a little over 2 inches. As stated in an earlier post it's not that much. However when you take into vertical dispersion due to velocity variations from extreme spread and your systems group size and the size of target you may slip outside the vital zone. Some medium game is around 7 inches and large game around 10 inches. For me I like to take in everything I can to get as accurate fire solution as possible. So I should be the limiting factor not my system. [/QUOTE]
