Ive usually always dumped them on the ground doing reloads or not, as thats how reloading them goes. Muzzle up and dump. At least they are more or less in groups where you dumped them, so find one, and you usually find them all. I usually switch to shooting revolvers more when there is snow on the ground, or at least powder or snow without a crust. Still a PITA with the crust, as the cases freeze to it. And you tend to break up the crust as you move around shooting and trying to recover the brass, depending on how thick it is.
