[QUOTE="ENGUNEER, post: 2624795, member: 69255"] Since there is a lot of discussion about the vapor trail here, I will write a quick note about it. There sometimes may be a vapor trail due to condensing water vapor but there is always a big effect that happens as the air travels through the oblique shock wave caused by the bullet. As this happens, the atmospheric air is compressed and the index of refraction of the air changes. This refraction change causes the bullet to look like a flying lens which distorts the light passing through it. That will be seen whether there is condensation or not. [/QUOTE]
