Doug, I'd need a pretty big tarp to be universally helpful. Since I'm shooting different guns, the landing zones for the brass vary with the guns' different ejection behaviors, and the bearings and distances from where I'm standing are all over the place. If I'm shooting my Thompson or M1 Carbine, I'll use a tarp because I'm usually set up back farther than for pistol shooting, on more standard length and texture of lawn. and it helps a lot. But for the trampled/mowed area, my recovery success is sufficient to forgo the hassle of messing with the tarp. If I decide to shoot, I can just go out and do it.

A while ago, before the grass was somewhat tamed, I fiddled with a screened structure made from old sliding door screens. It had a roof and a right hand side and was mounted on a parts rack on wheels I used to use for spray painting small things I could suspend form it. A small tarp on the ground completed the setup. I was still amazed both by how the brass could hide, and how different pistols' ejection groupings could somehow circumvent whatever capturing power was created.

I have a metal detector that I tuned to brass cases, but since this was basically a farm, the false positives made it not viable.

Everyone else with a similar range probably has an approach to the problem of disappearing brass, and I'd be interested in hearing about them and how they work.
