The Effects Of Temperature and Altitude In Long Range Shooting

Effects Of Temperature and Altitude Long Range Shooting

Temperature and Altitude are related in that they both affect air density and therefore the ballistic performance of a bullet. Lower altitudes and lower temperatures result in denser air, therefore more drag on the bullet and more bullet drop. Conversely, higher altitudes and higher temperatures result in thinner air, therefore less drag on the bullet and less bullet drop. When bullet manufacturers test their bullets, to ensure they are comparing apples to apples they use a standard which has been adopted across the industry at: Sea level; 78% humidity; 59 degrees Fahrenheit; and Barometric Pressure of 29.92. Here we present...
