On those very few occasions that I must use a public shooting range I recall seeing dozens of customers wading thru brass rolling around all over the place. Or sit next to a guy who buys a new box of ammo, shoots the whole box and neatly puts all the empties back in the box, walks away. Or friends of mine that shoot, actually bragging about all the brass they left on the floor. My shooting box always weighs more coming home than it did going there in the first place. Again .....waste not/want not.
