When we used to shoot the farms it was standard practice to carry all guns pointing down, unless we had dogs with us, and then all guns up.
For me, it's not important whether they are up or down, it's whether they are allowed to "wander" past other people in between!
Far too many airgun shooters still carry their guns by the scope and therefore point them at almost everyone else on the course.
