Which action is NOT allowed when at the shooting range?

Storing personal belongings behind the firing line is not allowed at the shooting range because it can create safety hazards. The area behind the firing line should be kept clear to ensure that no one is inadvertently put in danger during shooting activities. When personal belongings are stored in that area, it can lead to distractions or obstruct movement, which increases the risk of accidents.

Engaging in conversations while shooting can also be problematic; however, this option doesn't point to a specific safety violation as clearly as storing items behind the firing line. Pointing the rifle at the ground is an accepted practice if done safely and with the proper control, and firing the rifle in a controlled manner is actually a fundamental safety guideline. Those practices promote responsible handling of firearms.
