In the long-distance ring, temperature plays a much bigger role than simply how comfortable you are while shooting.
How does air temperature affect bullet trajectory?
- Ambient air temperature has an inverse effect on air density.
- This can create a balancing effect in elevation change.
- The change in air temperature can affect bullet drop measured in inches at some ranges.
- Air temperature also effects powders, making them burn hotter and faster.
As a refresher from the last few columns, the reason your bullet falls more by the time it reaches a 900-yard target than it does for a 100-yard target is because it was exposed to gravity longer. Therefore, the longer it takes to reach the target, the more gravity and wind will move the bullet off of its original path.
