I don't know how your ranges are set up or what you can take with you, but I have made a brass catcher out of a cheap canvas bag from Atwoods (a ranching store) and some scrap wood I had lying around. I had to shoot from a bench with it as it sat on the bench, but it caught probably 99% of the brass thrown at it. I plan on building another one out of PVC and a tarp that can be used while standing. It's a cheap and simple project that really anyone could do. Those who can't get down and pick through the grass for brass like they used to might find a something like this useful. The PVC design would also make it easy to disassemble for storage and transport.
