I can't find the post anymore, but I recall reading on one of these forums somewhere that there are ranges that consider all fired brass to be theirs. Kind of like the divine right of kings, or something they discovered in the Constitution that had previously escaped notice, like a penumbra.
Well, screw that. If I bought it, it's mine. It continues to be mine even though my gun just flung it a few feet away (or, in the case of my Luger, just hit me in the forehead with it.) If it's lying a few feet away and it can reasonably be assumed to have come from my gun, and nobody else claims it, I do intend to pick it up.
I'm fairly sure that Oakdale, which I belong to, does not have any such policy. But are there places that actually do have such a rule? And if so, please name them so I can avoid giving them any of my business.
