A friend of mine entered his car driver's side with his 30-06 pointed toward the floor on passenger side. It went off and shot a hole in the floor and the right front tire. He had a hard time explaining this to his brother, whose car he had borrowed. Not sure it was a 700, but I think it was.
He shouldn't have even touched the car with a loaded rifle. His fault! If he was hunting, he probably broke the law, whether intentional or not.
