Seems to my way of thinking that if you aren't in front of the line, you aren't on the range. I also can't think of any range I've ever been on where it was okay to move weapons around behind the line when the range was hot. In my mind, when a range is hot, all weapons are treated as loaded...it's only when a range is cold that they can be moved. Maybe he was just antsy because folks were down range servicing targets at the time?
"Certainly there is no hunting like the hunting of man and those who have hunted armed men long enough and liked it, never really care for anything else thereafter." -Ernest Hemingway, On The Blue Water: A Gulf Stream Letter
