Well, at my club, I put up a sheet of black fabric screen on the 4x4 roof support closest to where I am shooting. All my brass hits the screen and falls down. If I don't use it, my downloaded brass only goes a couple of feet to the right. I do this with the hard to find cases like .32 ACP, 9x18 and, when I owned them, TT33 and CZ52.
About the CZ52. Back in the '70's when I got my first one, the soviet ammo supposedly was for the PPsh and threw brass to hell and gone!
Later, we learned to make cases out of 5.56 cases (using expensive custom RCBS dies) 
and didn't want to loose our brass. We used to put a 15x20 painters tarp about 15 feet at our 4 o'clock position to catch the brass. 
I'm sure glad I don't own those things anymore. ( my eyes couldn't see the front sight anymore anyway.
