One thing, when a high powered rifle is fired in your direction, you will hear the lead go by first and then you will hear the report of the rifle. I had an uncle shoot at a deer and he didn' t know that I was just over a small rise from the deer. I heard the bullet go over head first and then I heard the report of the rifle. He actually fired three times at the deer, but the third bullet hit the deer, the other two went directly over my head.
