 That's the vapor trail. That's what you see whenever you're in a high humidity day. That's why as a sniper and a counter sniper, you always have your shooter and your spotter. Your spotter is there to ensure that when you pull the trigger and you come off target because of the recoil, that he's able to follow the vapor trail to see whether or not you impacted target or to be able to make the necessary corrections for you to get on target. So that's what you're witnessing when you're seeing that line. That's the vapor trail that is coming off of the round itself. And I agree with Pete, this is after the actual graze itself.
