Ive heard it called trace, vapor trail, wake, and in this area its commonly referred to as the wash.
Some guy might be heard to say that he called the shot on the wash. As a rule that same guy might be apt to say
other things in praise of himself. Some days everybody can and some days nobody can see it. Be carefull who you
listen to, especially on very long shots. Dont be affraid to ask the spotter if he (actually saw the bullet hit).
Make him answer that question. Dont be telling me im way high because thats where you last saw the bullet trail.
Sometimes its just best to quit shooting.
