I'm a member of the outdoor range here and since it's outdoor several people seem unconcerned with picking up their casings. I want to recover mine but when my Mini-14 for example throws them 10 or 12 feet into the grass among other casings it gets pretty tedious finding the warm one. There has to be a better way.

I also have a 9mm auto loader I'd like to recover casings from but the pistol range is all but carpeted with casings in the grass so that's the same story.

Is there a way to set up a bag or something of the sort to catch them? I've seen bags that mount onto the sides of ARs but I don't really see that working with my Mini-14 due to how far the bolt will move and I'm pretty sure that a bag wouldn't work on the pistol, either.
