I was wondering how everybody finds there brass. I live in the country and have my range in my back yard. The problem lies in the fact that no matter how short i keep my grass mowed its a bear too find all my spent brass.I was thinking about building a backstop out of aluminum 1 in sq tubing and string a tarp in it sort of like the backstop at a ball field only on a smaller portable scale with a tarp spread on the ground. I would like to know if anybody has done this or anything like it and how well does it work. I shoot a varity of guns and buying a brass catcher for each of them is not feasible. please post any designs or ideas or sugestions.
