is it possible to see your own vapor trails. i was out shooting the other night at a medal target out about a 180 yards and i believe i was seeing a vapor trail on the last i'm guessing 40 yards before bullet impact threw my scope. i had the sun to my back and it was just about to go down behind the mountain. the air just started to chill abit for the evening. i was using a .22 mag on a bipod and the scope was set on 9 power. i was shooting from the prone position so i could watch bullet impact threw the scope. at first i thought it was the grass moving from the energy as it went down range but the more i watched i could see it was not that. anyone else witnessed this before.
